Minutiae

“There’s something in the very small minutiae of life that tells us something about the big, big picture that we see every day all over the place, and so I think the more specific and creative and revelatory you are in the micro, the more powerful the macro will be.”

— Philip Seymour Hoffman

Don’t Sweat the Small Stuff ... and It’s All Small Stuff by Dr. Richard Carlson is a book I read years ago in one of my endless attempts to reduce my stress level It made a lot of sense. From his advice, “Choose Your Battles Wisely” is the phrase that has stuck with me. In raising kids or negotiating work situations, I use this measure to ask myself if I want to die on the hill of the conflict, or live another day in peace. This has served me to make better life choices.

After all, if we get caught up in the small stuff, we can get distracted from the bigger picture ... and lose sight of our ultimate goals.

Well, most of the time.

Thankfully there are some of you who have dedicated your work to the micro-level of science – the real (actual) small stuff – in order to attain real big picture results. This issue highlights products, innovations and ideas that take filtration to the next level ... down. Specifically, capturing harmful microscopic nanoparticles in air, gas and water from washing machines (p. 11), tainted air (p. 17), commercial gas (p. 21) and coal liquefaction (p. 38), and more.

Each article analyzes capturing harmful toxins and particles in filtration for the well-being of people, oh, and the planet. In fact, COVID-19 – invisible enemy #1 of 2020 – proved to be a compelling mass public

jolt into why this is so important, discussed more in “Air Quality: Define to Defend” (p. 34). Despite our best efforts (or are they?), indoor air quality is failing most of us. From wildfires, toxins, bacteria to allergens, our environments are really not built for best air quality situations. They are designed for cost efficiency. Define to Defend’s author says, “While the historic call for adhering to financial responsibilities always hovers in our minds, our social responsibility to avail the best IAQ is equally important. Enhancing indoor IAQ requires policies, relevant standards, and roadmaps to ensure implementation and compliance are entwined, not just the moral forces of the general public.”

And, don’t get me started on oceanic microplastics, a topic of such minutiae that it is not registering in the general public mindset. Why is that? Regardless, some of us do view the details differently to make better choices. Thankfully, filtration expert heroes are taking their experiences and offering us hope that we can battle the microscopic bad guys – a wise and worthy battle – and make our world cleaner for the next gen. In this case only, we should be sweating the small stuff ... every day!

SPOTLIGHT TECH

Cloud Brings Water Filtration Technology to the Smart Home

Cloud Water Filters recently announced the launch of their flagship product Cloud RO, an under-sink reverse osmosis water filter that allows customers to monitor water quality and consumption via the Cloud app.

There is a crisis sweeping tap water in America. A crumbling water system infrastructure, and the rise of emerging chemicals like PFAS, have more consumers searching for home water treatment solutions. Cloud is a new player in the residential “point-of-use” filtration space. Cloud’s flagship product, Cloud RO, offers an advanced alternative to reverse osmosis filtration. Cloud incorporates state-ofthe-art technology that controls pressure and flow within the system to maximize filtration performance. Smart sensors track water quality and communicate that data to the consumer via the Cloud app. Cloud provides its customers with visibility into their water quality, filter health, and consumption habits.

“This inside view has been lacking in the water filtration industry,” stated Cloud’s Co-Founder and CEO, Ben Zvaifler.

“Consumers need to know that their filter is working and that the water their family is drinking is clean and healthy,” he added.

Cloud is one of the first water filtration companies to focus heavily on the smart home. Water quality data is aggregated across all the installed devices to give Cloud a high-level view of water quality across the country.

In addition to connectivity, Cloud also delivers powerful filtration and adds healthy

minerals to the purified water. A multi-stage, reverse osmosis filter eliminates all of the top contaminants including lead, PFAS, fluoride, pharmaceuticals, and pesticides. After the water has been purified, a remineralization filter adds back calcium, magnesium, potassium, and other trace minerals. These minerals improve the water’s taste and raise the pH leaving the water alkaline.

Residential water filtration is on the rise as a multitude of problems erode the public’s trust in tap water. Nine million lead service lines deliver water to homes across the country, and the emergence of PFAS, or “foreverchemicals” has the EPA scrambling to set new health standards that will leave many water utilities in violation. In addition, new regulations around single-use plastics are encouraging families to ditch plastic water bottles and switch to an in-home filtration solution.

“The issues facing water quality are pushing more Americans towards point-of-use filtration.

“It’s a rising tide in a well-established $6 billion industry. Even though we are the new kids on the block, Cloud is well-positioned for immediate growth,” added Cloud’s Co-Founder and CFO Nick Braun.

Cloud launched earlier this year and has already shipped and installed systems in over 30 states. In their first few months in business, Cloud has filtered thousands of gallons of water, accounting for more than 20,000 water bottles saved. “It’s a metric we love to track,” said Braun, “We know we are doing good, and

my kids are blown away when they check our app to see how many bottles we are saving as a family.”

The price for Cloud RO is $750. Filter replacements are all usage-based, but customers can expect to spend about $200 a year on an ongoing basis. Cloud offers DIYers easy-tofollow video installation instructions as well as a handyman database for customers who prefer a professional installation experience.

Cloud RO is currently available online at CloudWaterFilters.com.

Based in San Diego, CA, Cloud is a water company developing connected filtration technology that allows users to track water quality from their smartphone. Cloud launched to the public in early 2023. Their flagship product, Cloud RO, combines design and technology to deliver the most advanced drinking water experience available.

Feed Spacers for RO filter elements

Water is essential for life, and having access to potable and safe water is one of the key factors in maintaining health. Water filtration systems play a critical role in ensuring that our tap water is free from contaminants and other impurities that can impact our health.

Veolia, a leader in water technologies, will lead, via its subsidiary SIDEM, a consortium in charge of the engineering, procurement and construction (EPC) on the Mirfa 2 desalination project commissioned by Abu Dhabi National Energy Company PJSC (TAQA) and ENGIE. Located in Abu Dhabi, this state-of-the-art Reverse Osmosis Desalination will be the third-largest desalination plant in the United Arab Emirates (UAE). With a production capacity of 550,000 cubic meters per day of potable water, it will provide clean drinking water to approximately 210,000 households while offering increased efficiency and a reduced environmental footprint. The contract represents revenue of approximately 300 million euros for Veolia. Project construction will begin in Q2 2023 so the plant can be commissioned by 2025.

Most of the drinking water used in the UAE comes from the sea. To manage the growth in water consumption and to compensate for the aging of existing facilities, mainly thermal desalination plants, the country has decided to use the latest advanced technologies and engineering processes to increase its desalination capacity while reducing its energy consumption. A strategy that strongly supports the country’s 2050 carbon neutrality ambition.

Relying on Veolia’s worldwide expertise in water desalination, the Mirfa 2 plant will follow the latest developments in environmental and efficiency standards for desalination, featuring advanced technological processes such as reverse osmosis, which represents strong efficiency gains compared to traditional thermal desalination, to lower energy consumption and improve productivity. These technological advancements allow to slash energy use by 80% compared to the 1980s, when thermal desalination was predominant. www.veolia.com

Naltex™ diamond nettings are used as feed spacers for spiral wound water filtration membrane elements for Reverse Osmosis, Nano, Ultra, and Micro Filtration. Naltex feed spacers are specifically designed to optimize the hydraulic conditions of the feed water by creating turbulence on the membrane surface which reduces fouling and pressure losses through the membrane element. These specially crafted spacers are made by a strong yet flexible plastic mesh that provides superior hydraulic flow capability which improves the flux of the membrane. In addition, their unique design helps to evenly disperse the feed water across the filter surface, providing optimal contact time with the filter media and improving overall filter performance. Naltex™ feed spacer technologies can improve the efficiency of your water filtration system by increasing the flux of each membrane element while also extending the life and robustness of a membrane element by reducing fouling on the membrane surface contributing to less cleaning and maintenance downtime.

Naltex™ diamond nettings are made of FDA approved materials, offering superior strength and flexibility.

Samsung Launches Less Microfiber™ Filter to Protect Oceans from Laundry Plastics

Samsung Electronics announced the launch of the new Less Microfiber™ Filter, an external washing machine filter designed to significantly reduce plastic microfiber emissions during laundry cycles. Designed with inspiration from apparel maker Patagonia and expertise from the global ocean conservation organization Ocean Wise, the filter builds on the success of last year’s Less Microfiber™ Cycle to substantially cut microplastics and enable sustainable laundry washing that is both effective and effortless. The new filter is now available in Korea and the U.K. and will roll out to other countries in the third quarter.

Porometer, a leading provider of pore size measurement solutions, has announced the launch of its latest product, the POROLUX™ Revo. Building on its reputation for innovation and cutting-edge technology, Porometer has developed a new instrument that takes pressure control to the next level, offering unrivalled accuracy and reproducibility in pore size measurement.

The POROLUX™ Revo features the patent pending MP² (Multistage Pressure Process) technology, which ensures a smooth pressure increase during the measurement process and speeds up the process of reaching flow and pressure stability.

This advanced pressure built-up process makes it possible to do measurements with smaller, perfectly uniform pressure steps, leading to the most accurate and reproducible pore size results.

One of the advantages of the MP² technology is the more gentle approach towards the desired pressure point, making it possible to register a data point even in the pore opening region. This results in a smoother wet and more detailed pore size distribution curves, providing users with even greater insights into their samples. www.porometer.com

“With microplastics emissions to our oceans continuing to increase and regulations being strengthened in many countries, as well as microplastics becoming a growing health concern for people everywhere, Samsung worked with Ocean Wise and Patagonia to engineer technology to prevent the release of microplastics from our daily life,” said Moohyung Lee, Executive Vice President and Head of R&D Team of Digital Appliances Business at Samsung Electronics. “With innovations like the Less Microfiber™ Filter and Cycle, Samsung is enabling Everyday Sustainability in a wider array of products and making eco-conscious daily practices second nature in the home.”

To enable customers to cut microplastic emissions from their laundry, Samsung first developed the Less Microfiber™ Cycle, a wash course that reduces microplastic shedding by 54% in part by leveraging Samsung’s proprietary Ecobubble™ technology. By using bubbles to help dissolve and absorb detergent, less heat and energy is required to wash clothes, resulting in reduced abrasion which in turn prevents microplastic emissions.

The Less Microfiber™ Filter takes this a step further, preventing up to 98% of microplastics released during laundry from escaping into the ocean, equivalent to eight 500ml plastic bottles per year when used four times a week. In addition, to help more customers get involved in cutting microplastic emissions, the Less Microfiber™ Filter has a mountable design style that allows it to be used with standard washing machine models, demonstrating the company’s dedication to long-term sustainability and helping customers embrace sustainability at home. www.samsung.com

A POSITIVE SPIN ON WHEELS & WASHING MACHINES

By Adrian Wilson, International Correspondent, IFN

In his memorable TedTalk from 2010, the great Swedish physician and academic Hans Rosling, who sadly died in 2017, proposed the washing machine as the greatest invention of modern times.

“I was only four years old when I saw my mother load a washing machine for the first time in her life,” he explained. “That was a great day for my mother – my parents had been saving for years to buy that machine. My grandma was even more excited. Throughout her life she had been heating water and hand-washing laundry for seven children and now she was watching electricity do that work. She was mesmerized – to my grandma that washing machine was a miracle.”

Rosling continues to make sound reasons for his nomination –not least giving women the time to read books – in an illuminating talk well worth watching.

However, the general consensus elsewhere is that the automobile is the greatest invention of the 20th century ... and the invention of the wheel the most significant in the history of civilization.

What was not widely known in 1952, however – when Hans Rosling was just four years old – was that advancements of both washing machines and automobiles have caused damage on the environment and now are threatening the future health of both humanity and the planet, as implications are become clearer.

Impacts of Progress

Scientists estimate there are around 14 million tons of microplastics on the ocean floor, and a further 24 trillion grains floating on the surface of the oceans – with 35% of this pollution generated from the turbulence and friction of putting clothing, sheets and towels through the washing machine.

Meanwhile, researchers from Imperial College London’s Transition to Zero Pollution initiative report that six million tons of tire wear particles are released globally each year, contributing to the microplastics problem, as well.

As tires break down they release a range of particles, from visible pieces of tire rubber to nanoparticles. Large particles are

carried from the road by rain into rivers, where they can leach toxic chemicals into the environment, while smaller particles become airborne and breathed in. They are small enough to reach into the deep lung and can contain a range of toxic chemicals, including polyaromatic hydrocarbons, benzothiazoles, isoprene and heavy metals like zinc and lead.

Despite this, research on the environmental and health impacts of tire wear has been neglected in comparison to the research and innovations dedicated to tackling fuel emissions. The Imperial researchers say that the effect of new technologies on the generation and impact of tire wear should be a priority.

“Tire wear particles pollute the environment, the air we breathe, the water run-off from roads and have compounding effects on waterways and agriculture,” said Dr. Zhengchu Tan, of Imperial’s Department of Mechanical Engineering. “Even if all our vehicles eventually become powered by electricity instead of fossil fuels, we will still have harmful pollution from vehicles because of tire wear.

“We urge policymakers and scientists to embark on ambitious research into tire wear pollution to fully understand and reduce their impacts on biodiversity and health, as well as research to reduce the generation of these particles.”

Solutions

Effective solutions based on advanced filtration for both of these problems are either in development or already exist, and can be expected to be widely implemented in the coming years.

GKD Group, for example, the leading woven mesh filtration manufacturer headquartered in Düren, Germany, has teamed up with Cleveland, Ohio-based CLEANR, one of a number of developers of advanced microplastics filtering technologies for washing machines

The two companies are collaborating on the development, engineering and manufacturing of CLEANR’s solutions which are said to efficiently filter microplastics from residential, commercial and industrial washing machine wastewater.

CLEANR’s patent-pending technology can be applied as an external filter or be readily integrated into modern washing machine designs as a pre-installed solution. The technology has been shown to capture over 90% of microplastic fibers larger than 50 microns in size. CLEANR also offers a consumer-friendly dry disposal mechanism that prevents hands-on contact with the microfiber waste and prevents it from being washed down the drain.

Pending Washer Regulations

“Washing-machine manufacturers around the world are facing growing demand for consumer-friendly, costefficient microplastic filtering solutions to address pending regulations in Europe, North America and beyond,” said CLEANR CEO Max Pennington. “Our partnership with GKD ensures the highest quality and precision manufacturing capabilities for our clients, based on GKD’s 100-year track record of woven mesh innovation.”

and distribution centers. This is an opportunity to help deliver a filtration solution that actually meets upcoming regulatory requirements for Europe and beyond.”

Legislation

A number of governments are studying the problem and developing new rules to curb the flow of plastic microfibers from washing machines into waterways. Beginning in January 2025, France will require all new washing machines sold in the country to include a microplasticfiltration solution. Meanwhile, members of the UK parliament, California, Illinois, and Oregon state legislators in the USA, and provincial legislators in Ottawa in Canada, are working through similar proposals, with other governments around the world following suit.

“The growing focus on microplastic pollution by consumers, governments, healthcare organizations and manufacturers of textiles, apparel and appliances has created a dynamic market with potential to achieve rapid change,” said Terry Moore, chairman of CLEANR’s board of directors. “By closely collaborating with washing-machine manufacturers and global leaders like GKD, CLEANR will help overcome the world’s number one source of microplastic pollution, while driving growth for our clients and shareholders.”

Tire Abrasion

GKD has also been closely involved with the Tire Abrasion in the Environment research project (RAU) with the Technical University of Berlin in Germany and is building on the results in the development of a year-round filter for road traffic applications.

“Microplastic pollution is becoming an urgent environmental and public health concern, but the microplastic filtering of washing-machine wastewater is a game changer,” added GKD Group CSO Stephan Kufferath. “We’re keen to help CLEANR achieve its market potential by leveraging our 50 micron stainless-steel mesh for capturing microplastics and long-established network of global manufacturing

“We worked with TU Berlin to identify hotspots, such as intersections that see a great deal of traffic and are currently developing a filter basket which is purged during the regular cleaning of conventional drainage shafts,” explained development engineer Dominik Herper. “This is then included in the standard maintenance cycle, which is both efficient and saves costs. However, this is no easy undertaking, since road run-offs catch more than just microplastics. In fact, they

“As such, our filter media must not only be very rugged, but also capable of reliably filtering road runoff water without getting clogged. It must also continue to perform over an extended time period, specifically between scheduled maintenance intervals.

“Our mesh expertise – coupled with the fact that we have been focusing intensively on the topic of microplastics since 2016 – provides clear benefits when developing products of this kind.”

Getting to a Global Solution

Microplastics are ultimately a global problem, Herper stressed, and it’s therefore important not just to have one solution, but approach the issue from various angles.

“As a general rule, the first step is always to prevent plastics from being released into the environment in the first place,” he said. “We know that tire abrasion from

road traffic is the number one cause of microplastics and less road traffic would certainly help, but this is unlikely to happen.

“In fact, tire abrasion is likely to increase even further as the modern world focuses increasingly on electric mobility because electric vehicles are heavier than their combustion engine counterparts and tend to generate more abrasion.

“Installing drain filters in locations such as major intersections is therefore an initial step that could make a meaningful difference. This would certainly reduce the proportion of microplastics in rainwater. However, it also requires a cost-effective solution, as well as corresponding legislation.”

Using BIOLOGICAL Particles as TEST AEROSOLS

Research Project Aeropore Provides Innovative Test Methods

By Bernadette Führer

Many biological hazards such as viruses, bacteria, fungi and allergens being present as airborne infectious or allergenic particles had a low profile in aerosol research until the COVID-19 pandemic. At the beginning of the pandemic, the main control strategies focused on the disinfection of surfaces and hand hygiene rather than virus transmission via air, which turned out to play the most important role regarding the source of hazardous infections. Measures, such as ventilation or air purification and face masks, that lead to a reduction in the viral load in the air we breathe, are therefore considered as the most effective protective strategy against infectious airborne pathogens (e.g., Ebola, influenza, endemic coronaviruses or molds) and against airborne allergens such as pollen spread via air.

Status Quo: Air Filter Evaluation with Non-biological Aerosols

The greatly increased transparency on the topic of bioaerosols in the scientific community and social media caused a significant increase in research activities as well as the need for solution concepts on efficient reduction options of these airborne pathogenic aerosols in indoor air, and vice versa. Thus, many innovative concepts are developed to enable lownoise and energy-efficient reduction of pathogens in indoor air. However, the efficiency of air purification to remove airborne pathogens in a real indoor environment can still only be estimated to a very limited extent at present. While established test standards with precisely defined test germs and conditions have been developed for decades in the field of surface hygiene, there is currently a

strong need in the field of air hygiene for test methods that can reliably measure and quantify the efficiency of measures to reduce infectious pathogens such as viruses in indoor air.

In current routine standard operations, non-biological aerosols such as salt particles, oil-like droplets or fine dust are applied for air filter evaluation (ISO 16890, DIN EN 71460-1, ÖNORM/EN 149). Regarding the investigation of air cleaners, there are promising studies aiming at more realistic indoor test scenario using e.g. NaCl aerosols (Küpper et al., 2019). While these particles represent the size of viruses, nanometerscale particle deposition is also largely related to the physicochemical properties of, for example viruses, which cannot be easily simulated by a saline aerosol. It becomes particularly difficult when it is

not a matter of pure filtration, but when the viruses are to be inactivated (e.g., by UV light ionization or electrochemical processes). Here, realistic experiments with infectious pathogens cannot be substituted, since the determination of the infectivity of the particles plays an essential role.

Testing with Real Airborne Microorganisms

Testing with real biologically active viruses, bacteria or allergenic particles, especially at large scales can be challenging and complex. However, they could support better understanding of infection control and pathogen transmission, especially for risk minimization instruments such as filtration systems in health care settings. As working with very hazardous and harmful pathogens is often not possible, the application of less harmful microbial model strains is recommended in several aerosol studies.

One possibility to mimic pathogenic viruses are bacteriophages, which are bacterial viruses infecting specific bacterial host cells, which means, they are nonpathogenic to humans. Although these bacterial viruses reflect the properties of critical pathogens such as Ebola, influenza or various endemic or pandemic coronavirus strains quite well, they can-

The Research Project AEROPORE

In the FFG-funded research project “Aeropore,” the Austrian Research Institute for Chemistry and Technology (OFI) together with the Center for Electron Microscopy Graz (ZFE), both members of ACR (Austrian Cooperative Research), have developed a novel filter test rig. This enables filter systems to be assessed not only on the basis of their permeability to particles in terms of number and size, but also according to their biological risk. Starting in autumn 2023, OFI expert Bernadette Führer will be researching in the project “AeroMobil” how this novel test facility can also be used in mobile applications.

not infect humans, but just bacteria. Thus, a high level of operational safety can be ensured. Bacteriophages might support and facilitate aerosolization studies and subsequently, prediction and estimation of behavior and reactivity of highly pathogenic airborne viruses.

As biological particles such as viruses behave differently and comprise detectable infectious potential compared to inert non-biological particles, it is important for the design and testing of filtration and ventilation systems to investigate the interactions between bioaerosols and filters as well as air conditioning and cleaning devices. These non-biological particles may represent the size of e.g. viruses but do not necessarily reflect the separation mechanisms on nanometric scale, which are often connected to physio-chemical characteristics of viruses, which cannot be simulated by an e.g. salt particle.

In general, it is known, that nonenveloped viruses are more persistent towards environmental stress such as temperature, relative humidity, irradiation via UV or disinfection agents, whereas in the case of enveloped viruses, additionally possessing a lipid membrane carrying, e.g. characteristic membrane spike proteins, are more sensitive towards environmental influencing factors. Furthermore, bacteria or fungal spores may change size and shape depending on

cell membrane and wall characteristics as reaction environmental factors such as desiccation, temperature, humidity or the presence of surrounding carrier fluids, droplets or particles. The potential of applied bioaerosols lies furthermore in serving as extension tool to commonly used non-biological aerosols such as salt or DEHS particles for evaluation of potential reduction of biological risk by e.g. air filters or Heating, Ventilation and Air Conditioning (HVAC) systems.

Breathe Easy: Insight into the Research Project Aeropore

Within the research project “Aeropore” conducted at OFI, an independent testing and research institute in Austria and member of ACR (Austrian Cooperative Research), the subject was intensified. In the course of the project, it was possible to develop a pilot-scale simulation filter test rig (at right) for testing air filters with airborne biological hazards belonging to biological safety level 1 (BSL1).

Even before COVID-19 pandemic the topic air hygiene and biological safety played a major role for OFI. Thus, the development of reproducible and comparable methods allowing the performance of single-pass tests using bioaerosols (determination of filter passage, fresh “air mode”) for evaluation of air filters from a biological and immunological perspective could be enabled.

 In protective gear, Bernadette Führer works with bioaerosols on the filter test rig set up as part of the "Aeropore" research project. OFI

Whereas everything started with a focus on allergens, pollen and fungal spores, the testing scope has been extended further during the course of the project. Working with bioaerosols containing bacteria and viruses used for filter testing was enabled at OFI within a second step, whereas the COVID-19 pandemic definitely enhanced transparency and attention on the topic.

It is known, that handling airborne particles functioning as test bioaerosol can be challenging. Each microbial strain or bioparticle requires proper preparation, sampling, aerosolization and detection techniques due to different characteristics and structural features of the biological particles, especially in airborne state. In addition, capability to survive as well as to maintain specific biological activity in airborne state is required by applied microbes for being able to detect them.

As there are very strict safety regulations when working with highly patho-

genic and infectious microorganisms such as SARS-CoV-2, influenza viruses, Ebola or Mycobacterium tuberculosis at laboratory, many research studies recommend safe and non-pathogenic models for human viruses.

To give an example, commonly used virus surrogates for aerosol experiments are MS2 bacteriophage and phi6 bacteriophage, which are also used at OFI for filter and air cleaner evaluation. MS2 bacteriophage, a well-known bacterial virus with an average size of 27 nm, was chosen as representative for a robust non-enveloped virus comparable to noroviruses. On the other hand, phi6 bacteriophage with an average size of 86 nm was selected as enveloped virus posing as a surrogate for Ebola virus or Coronavirus.

During method development, both viral surrogates were compared regarding their stability and recovery as airborne particles for testing air filters within

What is a Bioaerosol?

If an aerosol mixture contains biological material or microorganisms, the term bioaerosol or biological aerosol is used. Such a biological aerosol consists of living and non-living components or fragments such as pollen, fungi, bacteria and viruses. These differ in size:

• Size of fungal spores: most commonly observed size range of spores is 2 to 10 μm but can vary from around 1 to 50 μm

• Size of bacteria: 0.5 up to 4 μm is assumed depending on bacteria species as well as sampling and analysis techniques

• Size of viruses: 15-500 nm

• Size of pollen: average between 25 and 40 µm, subpollen particles (“Ubisch bodies” ~0.5 µm)

Testing with real biologically active viruses, bacteria or allergenic particles, especially at large scales can be challenging and complex. However, they could support better understanding of infection control and pathogen transmission, especially for risk minimization instruments such as filtration systems in health care settings.

OFI filter test rig. For checking the suitability of the selected strains as a stable bioaerosol recovery and viability after aerosolization into the test rig were investigated. Liquid aerosol generator from Topas GmbH was used for aerosolization of selected bioaerosols at different volume flow rates ranging from 40-300 m³/h for defined period of time per run. The nebulized airborne viruses sprayed into the test duct were sampled via collection filter media mounted at the end of the test duct followed by liquid extraction, which is just one of several bioaerosol sampling techniques.

The quantification of the viruses is usually done via double layer method by optically counting plaque forming units (PFU) being the golden standard for detection of bacteriophages. The method requires incubation of the host bacteria together with the sample solution containing the target virus at specific conditions. So-called plaques are formed by present bacteriophages as a result of infecting host bacteria, grown

Following general issues were important to consider during development of test bioaerosols applied within a filter test rig:

1. Stability and recovery of viruses, bacteria, fungal spores or allergenic pollen on surfaces.

2. Stability and recovery of airborne particles in airborne state after aerosolization within whole test duct.

3. Checking suitability of bioaerosol for single-pass tests for air filters, filter media and air cleaners.

More Research is Needed

The application of bioaerosols for a standardized air filter evaluation is still a black box within aerosol research and filter testing, which could be further opened for supporting estimation and

The implementation of biological methods within more realistic scenarios using selected infectious bioaerosols could be realized further within real-life test setups as, for example, within a car for evaluation of a car HVAC system.

A Woven Wire Mesh for ENERGY-EFFICIENT Filtration Processes

By Dr.-Ing. Martin Müller

The filter medium is the core element of every filter unit. The main task of the filter medium is to retain the impurities, which have to be deposited. At the same time, the filter medium needs to be able to withstand the chemical, thermal and mechanical stresses which occur. For an energy-efficient filtration process, the filter medium should have a high permeability and a large dirt-holding capacity, which is associated with a long service life. For filtration processes with a large dirt load, the filter medium should be easily cleaned (e.g., by pulsejet or back flushing). Many of these filtration properties mentioned are contrary to each other and cannot be combined in one filter medium at the same time. For example, a high separation efficiency due to a small pore size is always associated with a high flow resistance.

For demanding process conditions, (e.g., in the form of high-process pressures and temperatures or if sharp-edged particles have to be deposited), metallic filter media and, in particular, metal woven wire meshes are often used. Dutch Twilled Weaves, as one of the weaving types of woven wire meshes, are established filter media for the deposition of finest particles down to the single-digit micrometer range. To achieve these small pore cross sections, the weft wires need to be woven as closely together as possible. This results in a fabric with a low porosity, low free passage area and low number of pores, and therefore, a high pressure loss and power consumption of the filtration process. Furthermore, the narrowest pore cross section is located

inside the fabric, which is why this weaving type is very difficult to clean.

An alternative weaving type to produce finest wire meshes are the so-called Betamesh-PLUS fabrics. In these plain weave fabrics, the diameters of the warpand weft-wires as well as the pitches are combined in such a way that these fabrics are characterized by a high permeability, a high dirt holding capacity and ideal back flushing properties. Thus, the Betamesh-PLUS fabrics combine a large number of the advantageous properties in one filter medium. So far, these fabrics could only be woven for pore sizes of approximately 10 μm and coarser. By adapting the weaving technology and the wires used, it has yet been possible to produce this advantageous weaving type for energyefficient filtration processes down to geometric pore sizes of 5 μm.

Introduction

Filter cloths are the core element for the separation of particle laden fluid streams with filter apparatus and are frequently used in process engineering plants in all industrial sectors. In order to reduce the energy consumption of the filtration process, on the one hand the process sequence, such as the type and frequency of backwashing, can be subjected to optimization, and, on the other hand, the filter medium itself can be optimized. This work will focus on the second possibility.

Using metallic filter media, almost the complete range of filtration tasks can be handled. Especially in filtration processes with high-quality requirements, metal woven wire cloths are selected as filter media. In industrial applications, metal wire meshes are used – for example, in the separation filtration or solids recovery,

for clarification filtration, for the purification of fuels and hydraulic fluids, for water treatment and for the separation of dirt particles from polymer melts and solutions.

Due to their advantageous filtration properties compared to filter media of other materials such as plastics, textiles or ceramics, metal woven wire cloths have this broad application profile. The main advantages of the metal woven wire cloths are:

• With their regular and well-defined structure, metal wire meshes have a narrow pore size distribution [1] and guarantee an excellent separation and classifying accuracy. The pore size only depends on the type of weave, on the diameters of the used wires as well as on the pitches and can be determined before the cloth is manufactured[2]. Time- and cost-intensive weaving tests to calibrate the pore size are therefore not necessary.

• Due to their high chemical, thermal and mechanical resistance, metallic filter media can be used in demanding operating conditions, for example, given as high-process pressures and temperatures or sharp-edged particles, which have to be deposited.

• Depending on the type of weave, metal woven wire cloths can be easily backwashed[3] and thus ensure a long service life of the filter elements. This leads to cost savings compared to textile fabrics or ceramic elements.

The basis of the metal wire cloths are cold-drawn wires made of different metals or metal alloys. The used wire diameter varies between a few micrometers and several millimeters. Usually metal wires with a circular crosssection are applied, although stranded wires or ropes are also used for special applications. Parallel to the weaving direction pretensioned warp wires form the carrier material, into which the weft wires are successively drawn in. Depending on the combination of the warp wires and the weft wires during the weaving process, the production of different types of weave with different aperture sizes and different filtration behaviors is possible.

Types of Weave of Woven Wire Meshes

A over a wide range of pore sizes used weaving type is the Square Mesh. In a Square Mesh (see Figure 1, left), the warp and weft wires have an identical diameter and are interwoven at the same distance from each other, the so-called mesh width w. A low flow resistance and thus a low pressure loss during filtration can be achieved. The backwash properties of these fabrics are excellent. In addition to the plain weave shown in Figure 1, Square Meshes are also produced in twill weave. Mesh sizes of down to approx. 20 μm can be realized. To produce Square Meshes with such small pore sizes, very thin wires have to be used. They are very expensive and mechanically less stable.

In so-called “opaque fabrics” either the warp or the weft wires are woven in such a way that they touch each other and no mesh is visible in the projection. One of the most common opaque fabrics is the Single Plain Weave (see Figure 1, right), in which the weft wires are woven together as closely as possible during the weaving process. This results in a high degree of filtration accuracy. Both the diameter of the warp wires and the distance between

two center lines of the warp wires, which is called the pitch t, are larger compared to the weft wires. As a result, the mesh count of the weft wires is higher than the mesh count of the warp wires. The mesh count indicates the number of wires per inch. The disadvantage of this type of plain weave is that the narrowest pore passage is within the mesh in the triangular shaped cross section between the warp wire and two weft wires, making it more difficult to back-clean the filter media. With this type of weave, pore sizes down to approx. 45 μm are realizable.

If smaller pore sizes are required in a filtration process, so-called Dutch Twilled Weaves (DTWs) need to be used. In this weaving type, the weft wires are positioned as close together as possible and one weft wire overstretches two warp wires (see Figure 2, left). By shifting the weft wire one diameter to the side, a typical diagonal pattern is created. Dutch Twilled Weaves are an established weaving type in filtration applications. Pore sizes down to 5 μm can be realized. However, due to the pore geometry, they tend to clog, which results in a sharp drop in flow rates. This leads to a low dirt holding capacity and poor backwashing properties (see also next section).

p Figure 1: Model of a Square Mesh (left) and Single Plain Weave (right); warp wires: red, weft wires: grey.

p Figure 2: Model of a Dutch Twilled Weave (left) and Betamesh-PLUS (right); warp wires: red, weft wires: grey.

Betamesh-PLUS fabrics are a further development of Single Plain Weaves. The weft wires are extremely thin compared to the warp wires. During the weaving process they are shifted into each other to such an extent that partial deformations occur at their contact points. Due to the chosen wire diameters and pitches, the flow resistance and thus the pressure loss of this wire cloth is reduced compared to Single Plain Weaves and Dutch Twilled Weaves. So far, it was only possible to produce Betamesh-PLUS fabrics with a pore size of approx. 10 μm and coarser. By adapting the weaving technology, the fabric structure parameters and the mechanical properties of the wires, it has been possible to halve the pore size again. It is now possible to produce Betamesh-PLUS fabrics with geometric pore sizes down to 5 μm. These newly developed fabrics will be characterized in more detail below.

Filtration Performance of Betamesh-PLUS Fabrics

The Betamesh-PLUS fabrics are characterized with regard to their permeability, dirt holding capacity and cleaning behavior. The focus is on geometric pore sizes smaller than 15 μm. The Betamesh-PLUS fabrics are compared with Dutch Twilled Weaves. So far, this weaving type had to be used to achieve such small pore sizes. The production of the fabrics in a plain weave – as it is now possible in the Betamesh-PLUS fabrics – has not been possible yet.

The pore size of the wire cloth is characterized based on the geometric pore size. The geometric pore size is the diameter of the ideal spherical particle, which the brand new wire cloth can just pass through, filtering a liquid. The diameter is determined by a detailed geometrical description of the pore geometry. For details, please refer to the literature, e.g.[2]

Permeability

Figure 3 shows the flow curves for atmospheric air of Betamesh-PLUS fabrics and Dutch Twilled Weaves of identical geometric pore size. The curves of identical color have to be compared with each

other. The significantly greater permeability of the Betamesh-PLUS fabrics becomes clear. The reason for this is the greater porosity, the larger open area and the larger number of pores of these newly developed fabrics in comparison with the Dutch Twilled Weaves.

The increased permeability results in a reduced pressure loss. The possible higher flow rates lead to a higher amount of filtrate and therefore the productivity of the filtration process increases. The reduced use of resources and reduced operating

costs are directly linked to the reduced power consumption of the process due to the reduced pressure loss. Is in the filtration process an identical pressure loss and power consumption compared to a filtration process with a Dutch Twilled Weave as filter medium allowed, using a Betamesh-PLUS fabric the required filter area is significantly smaller. This saves installation space as well as reduces the weight of the filter element.

The Betamesh-PLUS fabrics are characterized by a low flow resistance com-

Dirt-Holding Capacity

The main task of a filter medium is to retain unwanted contaminations from the filtrate. The initial pressure loss is only present at the beginning of the filtration process. The contaminations retained by the filter medium continuously block

the filter media pores, whereby the permeability continuously decreases with increasing filtration time or retained particles.

Figure 5 compares the change in pressure loss as function of the specific filter loading, i.e. the mass of separated particles, of Betamesh-PLUS fabrics and Dutch Twilled Weaves when separating the standardized test dust Arizona Test Dust Coarse according to ISO 12103-1 from atmospheric air. Again, curves of identical coloration have to be compared

(fabrics with identical geometric pore size). When using a Betamesh-PLUS fabric, a significantly larger amount of dirt can be removed until the identical pressure loss is achieved compared to using a Dutch Twilled Weave. The BetameshPLUS fabrics are characterized by a greater dirt-holding capacity and thus service life.

Dutch Twilled Weaves have a small number of pore openings and their narrowest pore cross section is located inside the fabric in the triangular pore passage between the warp wire and two adjacent weft wires. Therefore, a single particle can block this pore. As a result, the pressure loss and thus also the power consumption of the filtration process increase sharply immediately at the start of the loading. The pressure loss increases massively until the filtration process transitions to cake filtration. In this filtration state, there is a linear relationship between pressure loss or pressure loss increase and filter loading.

In Betamesh-PLUS fabrics, the wire diameters and pitches are combined to each other in such a way that the narrowest pore is located on the outside of the fabric between two weft wires. This slotshaped pore geometry can’t be blocked by a single particle. If a particle is deposited, the flow still has sufficient free area to pass through. Supplemented by the large number of pore openings, this results in an only moderate increase of the pressure loss during loading. This larger dirtholding capacity means, that the filtration process runs for a longer operation time, before the filter medium needs to be cleaned or exchanged. This lower number of filter elements which have to be exchanged saves costs. The higher dirt-holding capacity is linked directly to reduced downtimes and consequently increases the productivity of the filtration process.

When the filtration process finally turns into cake filtration, the filter cloth only has the task to mechanically support the filter cake. Using a Betamesh-PLUS fabric, the cake filtration process runs at a significantly lower pressure loss level and thus power consumption level compared to the use of Dutch Twilled Weaves.

p Figure 6: Cleaning behavior of Betamesh-PLUS and Dutch Twilled Weaves of same geometric pore size.

p Figure 5: Change of pressure loss during the loading of Betamesh-PLUS and Dutch Twilled Weaves of same geometric pore size.

The filtration process is more energyefficient. All these benefits are present at the same geometric pore size and consequently separation performance compared to the Dutch Twilled Weaves.

Cleaning Behavior

The cleaning behavior by cleaning with a pulse-jet is investigated in accordance to DIN ISO 11057. Figure 6 shows the remaining pressure loss after a pulsejet cleaning in the different states of the filter medium (cycle 1-30: new filter medium; cycle 31-60: artificially aged filter medium). The artificial and thus standardized aging over 2500 cleaning cycles is indicated by the vertical black dashed line. If fabrics of identical geometric pore size (identical coloration) are compared, the advantageous cleaning properties of the Betamesh-PLUS fabrics become clear. The remaining pressure loss due to blocked pores by separated particles is lower. These advantageous cleaning properties are caused by the position of the narrowest pores on the outside of the fabric. Particles can be easily removed from this cross section by a pulse-jet.

As already mentioned, in Dutch Twilled Weaves the smallest pore cross section is in the interior of the mesh. Particles separated in this cross section can’t be removed easily, the remaining pressure loss and thus the power-consumption after cleaning is higher compared to the Betamesh-PLUS fabrics. The slit-shaped pores on the outer side of the BetameshPLUS fabrics have also the benefit, that if the separated particles are the recyclable fraction of the filtration process, a higher amount of the fraction can be extracted using this newly developed type of weave.

Summary & Conclusions

If pore sizes smaller than approximately 10 μm were required in a filtration process, Dutch Twilled Weaves had to be used up to now. Due to their low permeability, either the filter area had to be very large or the filtration process was associated with a large pressure loss and thus power consumption. Due to the low dirtholding capacity the filter media often had to be replaced or recleaned. However,

recleaning was only possible to a limited extent.

Herein, Betamesh-PLUS fabrics were presented in detail and subjected to a filtration technology evaluation. BetameshPLUS fabrics are plain weave wire cloths with a high porosity and a large number of pores. Pore sizes down to 5 μm can be realized. For their automated production, the weaving technology had been

further developed and the fabric structure parameters ideally adapted to the geometric conditions.

Due to the large porosity and number of pores, the fabrics are characterized by a high permeability and thus flow rate. Due to the advantageous slit-shaped narrowest pore opening on the outside of the fabric, there is no blocking of the fabric by deposited particles. This makes it

Overall, the newly developed Betamesh-PLUS fabrics make it possible to ensure maximum flow rates even with the smallest required pore sizes. As a result, the filtration processes are characterized by low power consumptions and thus energy consumptions. Energy-efficient filtration processes can be realized. Alternatively, the filter area and thus the installation space can be massively reduced with an unchanged flow rate compared to a Dutch Twilled Weave.

The advantages of Betamesh-PLUS fabrics explained here were only illustrated for the filtration of a gas flow. In case of the particle separation out of a liquid continuous phase, the described advantageous properties are also given.

Carbon Capture A Major New Field for Filtration

By Adrian Wilson, International Correspondent, IFN

Advancing next-level filtration, 3M is working with Svante Technologies to commercialize a filter media that can trap carbon dioxide (CO2) found in the atmosphere and permanently remove it.

Svante, headquartered in Vancouver, has developed a process for coating solid sorbents onto laminate sheets and stacking them into high-performance filters, which are available for both industrial pointsource capture – from hydrogen, cement, steel, aluminum, pulp and paper plants and refineries – as well as for direct air capture.

Solid sorbents, particularly metalorganic frameworks (MOFs), are a step

change for the carbon capture industry, Svante says. Their energy efficiency, resistance to degradation in the face of post-combustion flue gas impurities and low cost of ownership make them ideal for carbon capture.

Svante’s MOF captures CO 2 from diluted flue gas streams with high capacity and selectivity over water. It captures 95% of the total CO2 emitted from industrial sources, adsorbing CO2 using direct low-pressure steam injection for regeneration. The company has partnered with BASF, the world’s largest chemical producer, to mitigate supply chain risk and scale-up the production of its MOF sorbent materials from lab

to industrial scale, using a simple waterbased process and green chemistry principles to minimize environmental impact.

Storage Capacity

The tailor-made solid sorbents have a high storage capacity for carbon dioxide – a sugar-cube sized quantity of the sorbent materials has the surface area of a football field. The engineered and structured adsorbent filters can capture and release CO2 in less than 60 seconds, compared to hours for other solid sorbent technologies.

The Svante MOF sorbent material is said to be proven and effective at

separating CO2 from nitrogen contained in diluted flue gas from cement, lime, steel, aluminum, fertilizer, pulp and paper, oil and gas and hydrogen plants, and also has a unique resistance to SOx, NOx, oxygen impurities and moisture swing. It’s resistant to chemical degradation, which means less of a headache for operators and longer product lifetime.

CO2MENT

In May this year, Svante announced Phase 3 of the ongoing CO₂MENT Project with Lafarge, Canada’s largest provider of building materials, and Denver, Coloradobased Dimensional Energy, a specialist in technologies for abating CO2 emissions across multiple industries.

Back in 2019, working with energy giant Total, Svante installed a demonstration unit at the Lafarge cement plant in Richmond, British Columbia, to capture approximately a ton of CO2 emissions each day.

The project has enabled Svante to derisk its carbon capture technology in an industrial setting and for the past two years it has focused on increasing the efficiency of CO2 capture using its MOF filters.

Lafarge has meanwhile worked on finding a suitable end use for the captured CO2. Given the lack of CO2 transportation and sequestration infrastructure in southern British Columbia today, utilization of captured CO2 is fundamental to the decarbonization of large industries in the region.

Syngas

In Phase 3 of CO₂MENT, Dimensional Energy’s technology will convert the captured CO2 and green hydrogen to syngas, using its patented reactor and catalyst technology. The renewable syngas will then be further processed into liquid hydrocarbons which can be used in the production of industrial wax and other high value products that place the previously emitted carbon in an industrial use cycle.

Premium grade pure waxes produced from the process will be of interest to other offtake partners such as manufacturers of plastics, lubricants and cosmetics.

The project will include an ISO verified life cycle analysis (LCA) performed by a third party.

“Carbon capture is an important lever in our net-zero roadmap,” said Stephanie Voysey, head of sustainability and environment at Lafarge Western Canada. “However, for a carbon capture project to succeed, it must be paired with permanent geologic sequestration or utilization technology that will permanently isolate the CO2 in a specific media or product. If this pilot can be scaled to capture and use all facility emissions, it would be a first of its kind project for Lafarge and advance export and global adoption of this technology.”

“Finding pathways to the viable use of the CO2 we capture from industrial sites is

key in developing a circular carbon economy,” said Svante president and CEO Claude Letourneau. “We must do everything we can to capture and remove CO2 before it reaches the atmosphere. This type of partnership and project could make a significant impact if deployed at scale.”

Jason Salfi, Dimensional Energy’s CEO, added that turning one of the world’s most persistent problems into an asset would contribute to a circular economy in better harmony with nature.

“Leveraging existing infrastructure in difficult to decarbonize sectors of our economy is where we, as technology providers, can have an immediate impact on abating carbon dioxide,” he said.

“Our deep expertise in filtration technology, extensive global R&D community and unwavering commitment to create world-changing solutions give us the confidence to scale these carbonadsorbing solutions with the necessary speed to combat climate change,” he said. “3M is committed to helping build a lowcarbon economy and driven by a need to solve the world’s most pressing challenges and our partnership with Svante to create innovative climate solutions is an exciting prospect for us.”

“3M is another great addition to our network of world-class strategic partners and investors,” said Svante’s Letourneau. “3M’s more than 120 years of expertise in produc-

ing materials science-based solutions at scale is unparalleled and will aid us in our efforts to capture millions of tons of CO2 from diverse sites around the world.”

Because of the wide array of markets the company serves, Letourneau added that Svante’s technology can be applied to 85% of the rapidly escalating carbon capture and removal industry.

Record Fundraising

3M Ventures, the venture capital arm of 3M, recently participated in Svante’s Series E fundraising round, which raised a record-breaking $318 million to accelerate the manufacturing of the carbon capture and removal technology.

“With 51 technology platforms across 3M, we’re innovating and creating new technology capabilities to meet the growing needs of the carbon capture and removal market,” said Fabrice Moguet, senior vice president of research

and development for 3M’s Safety and Industrial business group. “To fulfil Svante’s needs and help combat climate change, we’ll need to scale to thousands of miles of technical material over the next few years, and we’re excited to manufacture our first products in the United States for Svante’s direct air capture applications.”

The joint development agreement between 3M and Svante will focus on solutions using parallel channel-structured adsorbent technology for sale into the carbon dioxide removal industry.

ADDITIVE MANUFACTURING OF MEMBRANES: Greater Design Flexibility and Higher Performance

By Rigoberto Advincula

Innovations in membrane and filtration manufacturing methods are essential to match the performance challenges or simply lower production costs. The reliance on conventional materials and production is both advantageous and disadvantageous. The market shifts with high-volume demand and the urgency to adapt to challenging situations. Take the case for the increased need for N95 masks and other personal protective equipment (PPE)s during the pandemic and the urgency to clean the air from pathogens.[1]

In membrane and filtration applications (including separations), a key driver for innovation is both performances and cost-oriented. While having a higher production volume on an existing production line or maintaining the supply chain of materials is more accessible, using tools, including digital manufacturing and artificial intelligence (AI)/machine learning to prepare for the next generation of materials and. manufacturing methods is essential.[2] There is a need to examine the recent advancements in materials and processes in 3D printing for membrane and filtration-related applications: ultrafiltration performance, adsorbents, module spacers, novel filtration and desalination membranes, applications in water remediation, catalysis, etc.

Already, 3D printing is driving innovation in many industries and academic research: aerospace, automotive, marine, healthcare, etc., and this should include the clean air and water resource sector. 3D printing enables the fabrication of complex designs and objects. Depending on a combination of tool fabrication and materials choice, it can be a fast, cost-effective alternative and highly desirable over conventional

membrane and filter manufacturing processes. [3][4]

In modern society, membrane separation and filtration processes are essential to provide supply safety, convenience, and scalability in manufacturing. It plays a significant role depending on the separation mechanisms, scale and size of the separation, and the flow or production rate. In the case of water purification, this can be at the point of access by the consumer or back to the production plant. Membrane processes can include microfiltration, ultrafiltration, and nanofiltration. Differentiation with membranes can simply be based on the famous Robeson diagram that plots selectivity vs. permeability, as shown in Figure 1. They are widely used in water purification (consumer), food and beverage processing, enhancement of bioreaction products, and other biotechnological applications.

In the pharmaceutical industry, which involves phase purification, antibiotic, and protein purification and production, there is a high demand for purity and even asymmetric separations. More complicated mechanisms involving field gradients can be found in reverse osmosis, electrolysis, dialysis, and electrodialysis.

Also, it should be noted that this can be pressure driven for all processes except electrodialysis. In water purification, the microelectronics industry relies on very pure water, and therefore nanofiltration and reverse osmosis membrane methods have to be used for this specific water purification. Appreciating the scale based on particle size and flux behavior is essential. Carbon capture and enrichment of resources can involve gas separation, vapor permeation, pervaporation, and membrane distillation. What differentiates

these processes, except for pervaporation, from other separation methods is that it consists of no phase change on the fluent. Regarding scale and size, dense membranes must be configured and utilized for gas separations (scrubbers, CO2 from natural gas, separating N2 from the air, organic vapor or acidic vapor removal from air or exhaust streams).

There is a need for different types of materials and fabrication methods for each of these applications. We have recently demonstrated enhanced CO2 separations

in 3D-printed silicone membranes (PDMS).[4] Figure 2 shows performance and calibration with previously reported separations. It shows the DIW-printed PDMS membrane and the mechanism and flux of gas separation through the PDMS membrane. The Robeson upper bound correlation plot showing the gas separation performance of PDMS-0S and PDMS-10S membranes compared to other membranes is vital as it puts the permeability and (e) selectivity of PDMS materials into context.

Additive Manufacturing (AM) is a fabri-

cation process using a “printing machine” for parts or prototypes by the “addition” of layer upon layer of materials based on a computer-aided design (CAD) model.[5]

The 3D model also provides exact dimensions and geometry that can be translated to an actual processing “twin” based on controlled parameters that align with the machine's capabilities. A tool path enables a precise axis orientation and boundary condition that further refines this fabrication process. The four stages of AM can be divided into four stages, as shown in Figure 3: 1) Selection of AM technology, 2) Design or acquisition of CAD file, 3) Conversion to an AM-friendly file or slicing, and 4) Actual fabrication by 3D printing. Although many reported methods exist, the technology can be divided into at least seven major categories. This includes material extrusion, powder bed fusion, vat polymerization, material jetting, binder jetting, directed energy deposition, and sheet lamination.

The choice of AM technology can be based on the materials used, the intended process of adhesion or curing, the quality or resolution of the final object or finished product, product specification or standardized properties, and finally, the intended application. In the membrane of filtration prototype or fabrication processes, it is possible that the parameter space for the application of AM will also depend on the environment and stresses that the object will be used. For example, in high-pressure and continuous flow applications, the membranes are expected to have thermomechanical properties (tensile, compressive, and flexural properties) that will not degrade based on the printing direction. By understanding the limitations of each method, it is possible to fabricate several unique geometries with peculiar flow or flux properties.

An example of AM method differentiation for membrane or filter application is as follows: In materials or binder Jetting technology, it uses droplets of liquid binder “glue” to join powders to form layers into a solid object. But the individual layers can have different compositions, defining the porosity based on powder size, asperity, and size distribution. The process is relatively

p Figure 2. 3D printed CO2 separation performance from a commercial-based silicone material: (a) DIW-printed PDMS membrane. (b) Mechanism of gas separation through the PDMS membrane. (c) Robeson upper bound correlation plot showing the gas separation performance of PDMS-0S and PDMS-10S membranes compared to other membranes reported in the literature.

simple and flexible in that the dispersion of the particles and choice of the binder are optimized for specific machines. Although in an actual filter or membrane application, it can have weak structural integrity at the interfaces due to poor binding properties and packing factors that degrade with constant flow and high pressures. In selective laser sintering (SLS), a form of Powder Bed Fusion that utilizes focused thermal energy with a laser or electron beam to deposit materials, the fusion or sintering is more robust. This is done by melting the materials (without needing the binder) and fusing them into the surface or layer formation process. This method can

generate better membrane operation properties since it fuses the materials themselves with a high energy output, e.g., laser, on a layer-by-layer basis. The choice of powders, polydispersity, blends of powders with other powders and additives, etc., can be the route to improve and create new properties. The fused materials will be limited based on their melting points and cohesive properties. However, the manufacturing cost can be expensive and may be prone to deformations caused by non-uniform thermal contraction and expansion, even during fabrication.

A cost-effective compromise may be obtained in material extrusion methods, which is a widely used AM technology. These methods include focused deposition modeling (FDM) or direct ink writing (DIW). In this case, the viscous or melted material can flow and deposit layer by layer. The starting materials can be polymer filaments, pellets, or viscous solutions of gels or adhesives that can be fed into a heated or nonheated nozzle to form layers. But it can have thermomechanical issues due to the formation of voids inbetween layers and the poor adhesion between layers.

Figure 3 shows our work on oil/water separation membranes based on 3D-printed silicone inks and their ability to retain performance after several cycles. [6] The ability to separate oil and water was built on the materials, including elastomeric properties. But the porosity was generated post-printing. In Vat Photopolymerization, which uses ultraviolet (UV) or visible light to initiate resin cross-linking to form 3D structures, high resolutions of the object finish can be achieved. The caveat is the lack of control over porosity because of the acceptable layer resolution (up to 50 microns). It can form high-quality material finishes with relatively low manufacturing costs but has issues with materials' selectivity due to the limited type of acrylate chemistry that can be used. This may be modified by using compatible reactive oligomers or telomers of polyurethane, polybutadiene, polysulfones, etc., in the case of polymer membranes. Finally, an interesting process could be the sheet lamination technique which forms an object by consecutive bonding of cut-out material sheets. Based on prefabricated layer sheets, the sheet can have a porous nature and thermo-mechanical integrity. This process can be used on various materials and can be of relatively low cost due to using pre-fabricated laminate sheets with built-in membrane properties. But it has a poor surface finish and perhaps poor bonding between layers that may delaminate over time. Furthermore, it has less accurate X-Y-Z control and can have difficulty creating complex shapes. Technological advancements will allow materials scientists and engineers to create complex 2D and 3D digital membranes and

work designs. The advent of AI in materials and manu-

including R&D and characterization methods, should

append the industry. New membrane designs can be acquired using 3D modeling software, 3D scanning, and 3D imaging. Furthermore, 3D scanning and 3D imaging methods can obtain the unique shape and size of the prototype object as XYZ-coordinates. Slicing will enable the conversion of CAD into command codes for the 3D printer. Printing parameters like resolution, print speed, operating temperatures, etc., can be set to determine its tool path or guide how each layer of the 3D model should be created.

This detailed explanation should give a quick appreciation of 3D printing in membrane and filter design since each layer can be considered a “separation unit” which can be stacked directionally against the flux of separation of filtration direction. A significant advantage is the appreciation of the material itself, which can have thermo-mechanical and porosity of barrier properties that can be compared with other filter materials, e.g., for polymers this can enable new properties in polyurethanes, polyvinylidene fluoride, polysulfones, etc. The differentiation is that in macroscopic properties from monolithic bulk membranes from conventional manufacturing, it is possible to build these properties on a layer-by-layer and directional basis. If printing is the actual generation of the product, then post-processing can offer even greater systems engineering for a filtration or separation operation. These post- or finishing processes can include embossing, drilling, cutting support structures, removing excess or loose powder, washing excess resin, post-curing or generating more porogen, etc. This may be needed to enhance system integration's final output quality and performance.

The rapid increase in research and development using 3D printing for membrane filtration, air filtration, desalination, and water purification applications, can potentially revolutionize the industry. New materials and 3D printers will emerge that are very specific for the membrane and filtration industry with highly controlled flow and flux behavior, higher printing resolution, better efficiency and speed in production, and, more importantly, broader material applicability in many demanding applications. This advancement can potentially reshape research and development in this industry. The future and prospects of 3D printing and new materials applications are bright.

AIR QUALITY: Define to Defend

By Dr. Iyad Al-Attar

We cannot keep dancing to the rhythm of wildfires, pandemics, and environmental disasters only to address the urgent air quality agenda. If we all aspire to having our cities be smart, our economies circular and our natural resources sustainable, we will need to embrace new business models and ways of living that take the planet, people and profit into account. That requires an agile strategy to address the “sustainability” pressing issues, whether air pollution and quality, thermal comfort, and energy efficiency or simply granting the planet a chance to regenerate itself. A healthy building envelope is essential to the wellbeing of human occupants, and therefore, air quality solutions should be established early on by design and not only by demand.

Sustainable urban development is not static and aims to achieve a prosperous society irrespective of living conditions and socioeconomic status. However, sustainable living cannot be achieved if we

merely focus on surrounding ourselves with urban designs that aim to impress rather than enable agile strategies to protect our built environment. Relying solely on evoking the pleasures of spectacular landscapes is insufficient to render our built environment “safe to occupy.”

The Air We Breathe

The air we breathe is full of microscopic particles, which can be hazardous to health and are, thus, considered a specific type of air pollution (Figure 1). The size of these particles is in the order of several nanometers to several micrometers. Epidemiological studies have shown, beyond doubt, an association between increased urban air pollution and adverse health effects on susceptible sectors of the population, particularly the elderly who may have pre-existing respiratory or cardiovascular diseases [1,2]. Urban air contains particles whose size may be classified as coarse to ultrafine (<0.1 μm in diameter).

Ultrafine particles contribute very little to the total mass in a sample of air. Still, they exist in very high numbers, which in episodic events can reach several hundred thousand/cm3 in urban air. Therefore, characterizing atmospheric pollutants is essential to understanding air filter performance and enhancing Indoor Air Quality (IAQ). Not all dust particles arise from human activity. High winds in desert regions and volcanic events are natural phenomena that cause high airborne dust concentrations. So, weather conditions, the natural environment, and human activities can cause windblown, construction, or fugitive dust, contributing to air pollution. High winds can raise large amounts of dust from dry, loose, or disturbed soil areas.

Wildfires and pandemics have remained the only nexus between achieving acceptable and best IAQ. The changing climate has modified weather patterns, influencing the levels and location of

p Figure 1: Scanning electron microscope images of various airborne pollutants.

outdoor air pollutants such as windblown dust (Figure 2) and pollen (Figure 3). Eventually, any changes in outdoor air quality will impact the IAQ as pollutants and aeroallergens infiltrate building envelopes through cracks, windows, and doors, bypassing the air filters installed in HVAC systems. In contrast, the increasing demand for adhering to sustainable built environments emphasizes new policies, technologies, and innovation to avail the best IAQ. Although financial responsibilities remain at the forefront of our minds, a similar emphasis should be placed on our social obligations to protect the wellbeing of human occupants.

Striving Not Surviving

The importance of air quality cannot be dismissed. For air quality to improve, the built environment should strive for bold and comprehensive air quality policies and solutions to integrate them into adaptive HVAC systems to respond to any variations to IAQ. Furthermore, the appropriate employment of quantitative and qualitative methodologies relevant to designing, building, and operating the built environment and its envelope are also of paramount importance. Sustainable air quality solutions entail gas phase and particulate filtration encapsulated with data-driven HVAC systems able to respond quickly to variating IAQ that affects the well-being of human occupants. No one would tolerate thermal discomfort or a crowded room with poor ventilation and air quality.

Sustainable Air Filter Performance

The different perceptions of air quality enhancements affected how filters were and continue to be selected and acquired. We must face that we cannot rely on ordinary air filtration products while we demand extraordinary IAQ. However, sustainable air quality and filtration strategies cannot depend on moral forces and increasing awareness alone. A face mask can help us navigate the pandemic, but cannot resolve the core air quality issues.

Air quality enhancement and filtration upgrades are frequently challenged and negotiated. Certainly, negotiation is welcomed if it is targeted to advance

air quality measures and hold HVAC responsible for the well-being of human occupants. However, what is not negotiable is the value of better air quality brought about to the built environment, even if the public’s perception of air quality value may differ from one person to another.

On the other hand, what should be promoted is the total cost of ownership once filter performance becomes the main criterion by which potential air quality value is achieved – independent of price. Furthermore, the total cost of ownership is the lifecycle-based assessment and forecast of all direct and indirect parameters and costs. Some of these considerations are appropriate filter design and media selection, HVAC operation and maintenance and air outdoor and IAQ monitoring which are key elements in the overall sustainable filter performance.

The scanned electron microscopic images shown in Figure 4 compare unloaded and loaded filter media with different scales.

Air Filter Selection

Research has revealed that the actual performance of the air filters installed in airhandling units tends to deviate from the performance predicted by laboratory test reports[3,4]. Various atmospheric airborne contaminants, moisture, and temperature can alter the air filter performance, and, therefore, their in-depth understanding of the physical and chemical characteristics and the climate conditions can prove invaluable for their appropriate selection and filter performance. Appropriate knowledge relevant to face velocity, particle concentration and size distribution, and temperature and humidity levels is essential to understanding filter performance. Other challenges confronting filter performance include upstream and downstream flow nonuniformity of filter pleats due to various media properties, cartridge design, and filter installation. In addition to filter loading characteristics and reliable velocity distribution, these parameters can influence the filter's efficiency and sustainable performance. Therefore, appropriate filter selection should be delegated to filtration experts who can provide

guidance and insights to enhance the air quality we eventually breathe.

The designers of the built environment and its envelope need to reconsider several other parameters aside from filtration. Construction materials, facades, wall thickness, roofing, heat loads, lighting and noise also play a role in rendering the building fit to occupy. Optimizing the final outcomes, whether thermal comfort, building energy efficiency, air filter performance, HVAC equipment selection, and better IAQ are critical to the general comfort of human occupants.

Considering that air quality is a byword for air filtration, the lifecycle-based assessment of filter performance parameters must be engineered to achieving better IAQ, which requires embarking on the following concrete steps:

• Conduct physical and chemical characterization of outdoor and indoor air to understand the pollutant types, concentration, and size distribution challenging installed air filters.

• Select appropriate air filters, media type, surface area (Figure 5), design,

p Figure 2: Scanning electron microscope image of dust particles recovered from loaded air filter.

p Figure 3: Scanning electron microscope image of pollen grain strained on the surface of air filter.

and the number of filtration stages required based on the findings above, the required flow rate, and the associated filter test reports.

• Ensure that air filters are operating in functional HVAC systems.

• Integrate air quality sensors for continuous monitoring and sustainable filter performance and assist the installed HVAC system in responding to any variation in IAQ.

• Identify the sources of indoor air pollution and tackle their emissions, including that due to human occupants.

• Conduct HVAC operation and maintenance measures accompanied by visual inspections.

Paying More Than Just Attention

The air quality issues faced today are manifest in our environmental behavior, how we choose to condition the air, and how we ventilate and filter the air. Enhancing

filter efficiencies may require more than retrofitting and frequently replacing highefficiency filters in the existing HVAC systems. After having characterized the outdoor air quality, defining the required filtration efficiency for a given building envelope is essential to selecting the number of filtration stages needed to attain air quality targets. Predictive HVAC maintenance programs and employing professional filtration plans can further foster healthy living environment for human occupants. However, the fluctuating momentum driven by pandemics and environmental disasters thwart any concrete plan for sustainable enhancements. Therefore, addressing the essentials of air quality and filtration technologies are paramount to raising the bar of sustainable living and to make our built environment contaminant and odor free.

It is our chance today to rethink, reenvision and reimagine how to attain air qual-

ity and employ several technologies, in addition to filtration, that can contribute to such an outcome. Chronic filter failures, and the addiction to washable filters have contributed to the deterioration of IAQ. Enhanced IAQ never gained the political traction needed to be a national priority, although the impact of escalating emissions has been well-pronounced. For decades, integrated air quality solutions have been frustrated by the complex structure and speed at which we now have to make decisions at all governmental levels – municipal, provincial, territorial, and federal.

Realignment

The paradox is that we desire enhanced IAQ, but more infrastructure is needed to support it. If infrastructure is defined as the fundamental facilities and systems accompanied by necessary services to serve a country, so should air quality. Air quality

p Figure 4: Scanning electron microscope images illustrating unloaded and loaded filter media with different scales.

should continue to be a pillar of our vitality, global economy, and the foundation of sustainable and healthy built environments.

Collaboration among governments, consultants, industry leaders, and end users is essential to resolve what is ailing in outdoor and IAQ and realign current anthropogenic emissions and air quality endeavors toward sustainability. The central task lies in eliciting cooperative behavior and collaborative efforts to protect the general well-being of human occupants. Yet, the first realignment needs to be by design and not just by demand. When planning for sustainable built-environments and their building envelopes, it is critical to shift emphasis to what they can become and evolve into

in the future if we are to embrace successful air quality strategies.

Let’s face it, environmentally speaking; we are running amuck when we consider the increased concentration of particulate matter and gaseous contaminants emitted annually. Allowing our outdoor air to deteriorate suggests that the consequences of poor air quality are acceptable for the built environment and the well-being of human occupants. The premise of continuing to pollute our air just because filtration technologies exist to capture them is unacceptable. Although air filtration technologies are the lowhanging fruit that designers can capitalize on in their endeavor to provide clean air, the question remains whether or not the

The Sands of Hope

While the historic call for adhering to financial responsibilities always hovers in our minds, our social responsibility to avail the best IAQ is equally important. Enhancing indoor IAQ reqºuires policies, relevant standards, and roadmaps to ensure implementation and compliance are entwined, not just the moral forces of the general public.

Dreaming of the best air quality will only bring us to our goals if progress translates our reality to a promising future of healthily built environments. Furthermore, aspiring to the highest standards of built environments requires architects of the unseen, experts of the unknown, and consultants of the unpredictable. If sustainable healthy living is to be embraced, we must define air quality before we defend it. Ultimately, if air quality and filtration strategies are drafted on the sands of hope, left without actions, they will soon see the sea.

Innovating Tubular Filtration

2022 AFS Engineering Merit Award Takes Metal Filtration to a New Level

A stand-out company at the spring American Filtration Society FILTCON 2023 was Spectubular Technologies, makers of Precision Micro-Cut Filter Tubes. Their innovation took home the society’s coveted 2022 AFS Engineering Merit Award for their new filter element produced from seamless metal tubes through a proprietary, patented laser cutting process. They are produced from a single homogenous layer and offer significant benefits over traditional metal mesh, sintered metal, and multi-layer metal fiber filter elements.

Tubular Perks

Advantages of the company’s Precision Micro-Cut Filter Tubes provide greater durability in high temperature, high pressure, and corrosive environments, resulting in longer element life and reduced maintenance costs. The manufacturing process produces higher quality control on pore size. This technology works well for lower micron ratings from wedge-wire with similar or better flow (open area) and produces a better cleanable finish. The filter tubes were designed and developed to address specific challenges encountered with traditional metal filter media technologies. Easier cleaning and maintenance reduce production downtime and energy required for backwashing the filter element. Reduced material content (support structure and multiple media layers are not needed) result in a more cost-effective filter element. The process is designed to produce filters to custom specifications. These tubes are particularly beneficial where long-lasting back washable solid to liquid filtration of micron-level particles is required. This would include liquid filtration that is in sticky, sour, or critical service around higher temperatures or harsh environments. They could be applicable in most applications that use metal mesh, sintered media and porous or perforated metal filter elements.

Current Application

The filters are currently used in Fischer-Tropsch reactors in coal liquefaction. Syngas is converted to a synthetic crude through a series of reactions assisted by a catalyst. The syncrude is then filtered from the catalyst so that the syncrude can proceed to the next section and the catalyst can be recycled in the reactor. The Spectubular Technologies Precision Micro-Cut Filter Tubes could be an advantage for applications where the catalyst is protected by upstream filtration or a downstream collection of materials. Note, that catalyst loss is a very significant concern in refineries, as some are precious metals.

Traditional perforated tubes tend to have much larger openings where the Spectubular Technologies Precision Micro-Cut Filter Tubes can be as small as 10 microns and go up to 100 microns.

p The R&D team celebrate their invention: Wendy Beach, Director of Business Development, Synfuels Americas; Stephen Truncale, Director of R&D, Synfuels Americas; Chris Selley, President, Precision MicroFab; and Judd Swift, President and CEO, Synfuels Americas.

Traditional perforated tubes tend to have much larger openings where the Spectubular Technologies Precision MicroCut Filter Tubes can be as small as 10 microns and go up to 100 microns. Currently used mesh and sintered media have multiple layers through which a particle would need to travel and can get stuck within the media. This requires more time and energy to backwash and a shorter lasting filter.

Product Inspiration

Judd Swift, President & CEO of Synfuels Americas, is quick to extend much of the credit of the Spectubular Precision MicroCut Filter Tubes to Dr. Yong Wang Li, the founder and president of Synfuels China Technology Co. Ltd., a Beijing-based company focusing on advanced conversion technologies for coal, natural gas, and other energy assets. Dr. Li is considered one of the world’s top scientists focused on FischerTropsch technology. As a leading professor at the Chinese Academy of Science and the director of the National Energy Research Center for Clean Fuels, Dr. Li leads a research team that carries out advanced research projects in industrial conversion processes. He has published more than 500 scientific papers and obtained more than 80 authorized patents. His research has won several international awards.

Dr. Li is also the Chairman of Synfuels Americas Corporation, the global platform for Synfuels China Technology Co. technology licensing, located in Dulles, Virginia.

“While working with the USA team,” explained Swift, “Dr. Li came up with the initial, high-level concept for a new type of filter that would be made from a seamless metal tube for use in the Synfuels China Fischer-Tropsch reactors. Its design would exceed the life and efficiency of filter solutions that are currently available. The filtration challenge for Fischer-Tropsch reactors is that the process must keep the valuable 20-micron catalyst inside the reactor while allowing the fluid to move quickly on to the next stage. The reactor operates at a temperature of 270°C, a pressure of 10 Bar, a pressure differential of 2-3 Bar and a plant is producing up to 100,000 barrels per day of liquid fuels.

Synfuels Americas was tasked with the job of developing a new filter design to outperform the existing filter solution that would be better able to withstand the extreme conditions and harsh environments.

R&D Ensues

Synfuels Americas’ established a new R&D filtration division, called “Spectubular Technologies,” which is led by mechanical

engineer Stephen Truncale. He oversees the laser lab operations, which are in the Baltimore Maryland area. The Spectacular Technologies team works with engineers from prospective companies to develop multiple filter concept designs for testing. In the case of Synfuels China, the diameter and length specifications of the final filter product were fixed, however other aspects of the filter tube were variable and therefore needed to

be tested. This included testing different materials, material thicknesses, and slot geometries. This in turn required continual modifications to the filter production process and refining of the cutting parameters.

Many iterations of the precision microcut filter tubes were developed and sent to the customer testing locations to collect data on the performance. As performance data was gathered, certain aspects of the

filter were refined or emphasized until the desired results were achieved and declared to be successful by the customer.

Catalyst Recovery

“Spectubular Technologies Precision Micro-Cut Filter Tubes are currently being used for catalyst recovery in FischerTropsch reactors in the energy industry,” shares Truncale. “Traditional filter media, such as wedge wire or wire mesh, offer a more arduous path for the catalyst and fluid to pass through which, as particles are captured, clogs the filter. In contrast, using our newly-patented thin-walled filter element, the catalyst are easily backwashed and thoroughly removed allowing for a longer lasting filter. This allows Spectubular Technology customers to benefit from an improved and more cost-effective process.”

The Bright Future is Tubular

“Our Spectubular system currently has the capability to process material in a 10 mm to 30 mm diameter range,” Truncale states. “We have received significant interest in larger diameters from several interested customer prospects. Based on this customer feedback, we are working to extend our capabilities by enhancing our patented systems to enable us to process diameters of 100 mm or more. This will allow us to extend our product range and reach out to new potential customers and applications.”

CEO Judd Swift comments that “while this innovative filter technology is primarily used in the energy industry, we plan to partner will other filtration experts to expand to additional markets and applications. We believe that our patented filter technology can provide a better, more cost-effective solution for many solidliquid filtration applications that require micron-level filtration.”

The use of this filter Swift believes will be next generation for applications that require a cleanable and reusable filter, as it can be more effectively backwashed, extending filter life and reducing maintenance and downtime. In their vision, this is marketed as a “green” solution, helping to position the filtration industry as a key player in the fight for climate control.

The Path to Finalizing New Standard for Infectious Aerosols

On May 15th, ASHRAE notified the market and public that a draft of a proposed standard for control of infectious aerosols, ASHRAE 241P, was available for review and comment. This proposed standard is the output of work previously announced December 9, 2022, “ASHRAE’s board of directors today announced its commitment to support the expedited development of a national indoor air quality (IAQ) pathogen mitigation standard. The goal is to finalize the consensus-based, code enforceable standard within six months.” Consistent with efforts to expedite the development and implementation of this standard, the commenting period was limited in duration and closed on May 26th.

ASHRAE voted to approve the final draft of the standard on June 30, and it was applauded by former White House COVID-19 Response Coordinator Dr. Ashish Jha. “This effort to try to improve indoor air quality and reduce the burden of respiratory pathogens is something we have talked about at the White House – a lot of experts have been talking about it,” said Dr. Jha. “Talking is important, but what ASHRAE did over the last six months in building out Standard 241, that just got approved, fundamentally changes the game. It is one of the most important public health interventions I have seen in years, if not decades. It is really heartening to see this organization take a central role in tackling the biggest challenges facing human health in the U.S. and around the world.”

effects on fair competition,” “not stifle innovation and technological development,” and that “standards are instrumental in helping to more rapidly allow multiple companies to compete at various points throughout supply chains, thereby reducing cost, improving competitiveness, and enabling continuous innovation.” To ensure efficient validation that products adhere to standards and to promote innovation, test methods in standards should “offer definitive precision, accuracy and reliability (PAR) statements. The (PAR) is based on Precision & Bias (P&B) data achieved through an Inter-Laboratory Study (ILS). An ILS is a mandatory aspect of all ASTM standards that demonstrates how effectively different operators, laboratories and test instruments implement the method, which ultimately defines the precision, accuracy and reliability.”

INDA, in its role representing the nonwovens and engineered materials industry, collected input from manufacturers of filter media and provided the statement below.

To Whom It May Concern:

Our organization, INDA – The Association of the Nonwovens Fabric Industry, has reviewed the proposed ASHRAE Standard 241P “Control of Infectious Aerosols” and would like to provide the following comments for consideration before adoption. As an organization comprised of companies that provide the physical filter media, we will limit our comments to those relevant to those materials.

As director of education and technical affairs, Matt presents regular training related to nonwovens and filter media from INDA’s headquarters in Cary, NC.

For more information about upcoming training opportunities, visit inda.org/training

Standard 241 establishes minimum requirements for controlling infectious aerosols and reducing the risk of disease transmission in new and existing buildings. Included are requirements for both outdoor air system and air cleaning system design, installation, commissioning, operation, and maintenance to reduce exposure to infectious aerosols.

Advising for Common Sense

INDA – The Association of the Nonwovens Fabric Industry’s philosophy for new standards and test methods reflects that of WTO and standard development organizations such as ANSI, ASTM, TAPPI and ISO, in that standards should: “Effectively respond to regulatory and market needs,” “be performance based as opposed to design prescriptive,” “have no adverse

Founded in 1968, INDA member companies represent the entire nonwovens value chain including raw materials and roll goods producers, machinery manufacturers, converters, and brand owners. INDA works each day to fulfill our mission of “fostering member and industry success through its activities.” INDA provides thought-leadership in innovation and technology through conference content, recognition awards, and industry reports; protecting markets that are important to our members through focused product stewardship; advocating for industry sectors impacted by regulatory or consumer-driven issues; and organizing face-to-face interaction through industry expositions and events.

lions more in indirect economic impact and sales to end users. INDA members include the manufacturers of thousands of durable and disposable products such as personal care items, hygiene products, PPE, medical equipment, construction materials, automotive fixtures, and filtration media.

As a general tenet, INDA strongly supports standards that are based upon scientific evidence that has been peer reviewed and is not prescriptive with respect to future product innovation. The rich history of innovation in filter media has provided multiple options for meeting MERV 13 and higher air filtrations requirements.

We recognize that proposed Standard 241P is specifically targeting control of infectious aerosols and is not meant to displace other indoor air quality standards. With this in mind, as the CDC has provided the scientifically supported guidance that MERV 13 is the minimum requirement to achieve the desired control of infectious aerosols, we recommend that only MERV 13 and higher filters be addressed by this standard. This provides consistency between guidance from national health agencies and the proposed standard.

As noted above, innovations in filter media, both with and without electrostatically charging, have provided a number of options to achieve the performance requirements described in Standard 241P. The proposed standard attempts to ensure that filter media meet minimum filtration requirements throughout its designed useful life and includes a discharge conditioning step to comply with the MERV-A performance beyond January 1, 2025. The following comments regarding the discharge conditioning pertain only to those filter media that are electrostatically charged to boost performance. Other compliant media available today, that do not use electrostatic charging, should be unaffected by this requirement.

In so far that Standard 241P references ANSI/ASHRAE Standard 52.2 (section 4.2.3) and in 2025 will make mandatory a conditioning step, as provided in Appendix J of Standard 52.2, we believe recent actions related to that standard should be considered. In February 2023, when proposed to make this conditioning step mandatory rather than optional, the proposal failed passage and it was recommended that a study be done to obtain scientific understanding of the efficiency loss in electrostatically charged filters. As Standard 241P is linked to Standard 52.2 by reference, we believe that the scientific study recommended by the committee for Standard 52.2 be completed to ensure that the discharge conditioning method is meeting the intent of Standard 241P and appropriately reflecting the performance of filter media.

As the test methodology required for the MERV-A filter media conditioning step, it is noted to have appreciable variability and lab-to-lab variance. We encourage ASHRAE to address these concerns while completing the study recommended by the ASHRAE 52.2 Standards Committee pertaining to Appendix J. To alleviate the concerns pertaining to lab-to-lab variation, it is recommended that labs evaluating filter media have third-party certification for the appropriate methods.

The filter conditioning step required for MERV-A, provides the additional data point of “worse case” performance for electrostatically charged filters, which, considering the goal of infectious aerosol control, has some value. Coupled with the best case/fresh out of the package MERV rating, the breadth of filter capability is potentially identified. While an improvement over a single data point, this still neglects the performance during the majority of the product life. ISO 16890 recognizes this shortcoming and attempts to address this via an average of “as is” and “conditioned” filter performance. Of course, for media that is not electrostatically charged to boost performance, these values should be essentially the same. A final note here – the mention of ISO 16890 was not to suggest that ASHRAE Standard 241P should follow the ISO approach. While there is value to standard harmonization, that effort is out-of-scope here.

One key indoor air quality learning from the COVID-19 pandemic is that filter media has often not been changed with appropriate frequency resulting in higher operational energy costs, increased maintenance costs, reduced equipment operational lifespan, and most importantly lower-performing air filtration and control of infectious aerosols. In many instances, it has been noted that the failure to replace filter media was due to the cost of the media itself. With the goal of controlling infectious aerosols, consistently over time, there is a need to be sensitive to the total implemented costs, including media and operating costs.

Considering this, it is anticipated that there will be increases in both the time and cost of testing filter media using the methods required for MERV-A, as provided by ANSI/ASHRAE Standard 52.2 Appendix J. These costs will of course be incorporated into the cost of the filter media, potentially exacerbating the issues with timely filter replacement. Thus, it is of high importance that there is confidence in the test methodologies to avoid excessive testing and/or re-testing and that the methods are adequately reflecting filter media use behavior.

Lastly, it should be noted, that by requiring MERV-A 13 performance there will be many instances of filter media operating with higher pressure drop which will translate into higher operational energy costs. Eventually, this will drive innovation to achieve the desired levels of infectious aerosol filtration in a more cost-friendly operational manner, but many short-term solutions will have a higher energy and/or carbon footprint. Long-term innovative solutions may contain combinations of technical approaches, both old and new, to achieve the combined performance and economic aspects to ensure improved infectious aerosol control.

“The CDC has provided the scientifically supported guidance that MERV 13 is the minimum requirement to achieve the desired control of infectious aerosols, we recommend that only MERV 13 and higher filters be addressed by this standard.”

To Tell the Truth

Sell-Side M&A Versus Estate Planning

We are constantly hearing that a family business owner is “going through an estate planning” initiative to understand their potential value. In many cases, the value created from a competitive M&A process is a better use of time.

The professional industry supporting estate planning has a good reputation. It has a comprehensive network of knowledgeable advisors with strong academic backgrounds, subject matter expertise and it is an area that is heavily regulated. In a broad sense, these estate planning professionals include accounting, financial advisors, commercial bankers, real estate, community stewards, wealth planners and legal advisors. Please note, the author has great ties with members of these professional organizations.

Let’s not forget the “non-professional” members supporting the business owner. This group includes the multi-generational extended family members. This mix includes current and former spouses, uncles, aunts, in-laws, children and grandchildren of the owner.

An evolving third element in the estate planning game involves the university and religious institutions that are extremely active courting the

business owner. Also not to be forgotten are the private undergraduate and elementary schools looking for a charitable contribution when your grandchild graduates from third grade.

• Do these various groups have an impact on how the value of the business is determined for estate planning purposes? You bet they do!

• Do these various groups attempt to sway discussion on the value determination?

Unfortunately, yes.

• Do these various groups agree with the ultimate decision regarding valuation? No.

Enter your experienced investment banker to lead a sell-side M&A process for the business owner. Creating a competitive M&A sell-side process will provide a value that the market is willing to pay for your business. I would like to review some actual advisory scenarios involving families:

Case Study #1

• At the passing of the parents, CEO is gifted additional shares to become 51% majority owner of family business. Two (2) siblings (not involved with the business) given 49%, in aggregate.

• Siblings want to be “bought out.”

• Three years later, with high professional expenses deployed and multiple estate valuations rejected, an agreement for a valuation is agreed upon with CEO now controlling 100%.

• Six months later, the company is sold for 2x above the estate planning valuation.

• Professional estate planning advisors followed the conventional conservative practice to generate the valuation.

• Conversely, the M&A market spoke loud and clear that the company’s niche was more valuable in a competitive process.

Case Study #2

• Founder passes and provides children (3) from first family 58% ownership, while his

stepchildren (3) receive 42% of the family business.

• Founder had established a 70% super majority vote requirement on all business initiatives. Since this threshold was established 35+ years ago, the 4 children/ stepchildren have never had a vote pass due to the 70% threshold.

• Professional estate planning advisors followed the wishes of the founder and saddled the next generations with a challenging burden at exit.

• The investment bankers were highly confident the business market value of $200+ million would be attainable.

Please consider all your options and tools when considering your estate planning initiatives. We would encourage you to ask your team of professional advisors to invite an investment banking team to speak with you and your family to further evaluate your options.

$15 Billion Industrial Cartridge Market

The industrial cartridge filter market generates revenues of more than $15 billion per year. This global number is useful to determine whether the market is large or small. But it would be a mistake to attempt a top-down segmentation. In fact, this number is an aggregation of $15 million sub niches which in turn can be split and aggregated into many millions of forecasts.

The niche creation is similar to LEGO® where 1,000 pieces can be used to create a billion unique objects.

Management is not accustomed to acting on this level of detail in forecasting, but, on the other hand, insists that it is insufficient to predict the total cost of paint and it is necessary to determine how much will be spent for each product.

The equipment supplier needs at least 28,000 forecasts by country, cartridge type and application for at least five years going forward as well as the last five years. Period. There should be analyses of the various processes in each major industry and the facts and factors surrounding cartridge selection.

Each salesman will be interested in a different combination of these 28,000 sub-niches. In the case of large industries, such as food, there will be the need to segment by state. California is a larger market for food cartridges than all but a few countries.

The forecasts include only filter elements. Separate forecasts are needed for housings and media, fibers and resins. There is no reliable outside source for any of this data. So, iteration is important. Forecasts for resins, media, filters and housings provide this iteration.

Pharmaceutical is the largest segment with 2022 cartridge revenues of over $5 billion – $1.2 billion is in the U.S.

Forecasts by country are particularly important for the major countries, and are needed by regions.

The analysis by trading zone is quite important. Most trade takes place in a 3,000-mile radius. Europe and Asia have very successfully traded in their zones while the Americas has a relatively low amount of trading activity.

The largest cartridge suppliers for industrial applications are also the largest in the pharmaceutical segment. The substantial investment to meet the high-performance requirements compared to costs of doing business internationally has resulted in the high technology companies becoming global and achieving substantial size. Pall, Millipore, and Sartorius have nearly a quarter of the total market and nearly 50% of the pharmaceutical segment.

The top three suppliers are averaging annual revenues for industrial cartridges in excess of $1 billion each. Suppliers three to 10 are averaging $300 million. Suppliers 11-20 are averaging $100 million.

The market can be divided into high and general performance. Small companies account for 40% of the total market but only 13% of the high-performance segment. These companies are offering general performance cartridges to the local market. Liquid cartridges are manufactured along with bag filters and dust collector cartridges. Customers can be end-users, system suppliers or filter suppliers of whom purchase custom made filters.

Sales forecasting has not been as detailed as cost accounting because of the cost and difficulty of making accurate forecasts. However, a holistic approach distributes the costs over many subjects. Most of the facts and factors are relevant to many forecasts.

The organized approach needed for detailed forecasting can be extended broadly. Ultimately markets are greatly affected by voter choices. Voter life quality goals can be made using the same approach which has been labeled the Internet of Wisdom (IOW). An industrial version (IIOW) has steadily been expanded over the last decade. The predictions for artificial intelligence to change life and business is likely to be achieved when incorporated in the Industrial Internet of Wisdom.
