DuPont Launches Digital Tool to Estimate Sustainability Impact from the Use of Water Treatment Technologies

DuPont recently introduced the Water Solutions Sustainability Navigator, the first digital tool designed to help users estimate key sustainability indicators when using various water treatment technologies, whether from DuPont or from other manufacturers.

The Water Solutions Sustainability Navigator enables users to compare how different potential water treatment scenarios impact sustainability indicators, including carbon emissions, chemicals used, wastewater generated, solid waste generated and footprint needed – with all calculations and indicators validated by a third-party verification performed by LRQA, a global assurance provider.

Carbon emission calculations are in conformance with ISO 14020:2001 and 14021:2016, and chemical, footprint, wastewater and solid waste calculations are in conformance with ISO 14020:2023 and ISO 14021:2016 + A1: 2021.

“While there are many factors that can influence the design and selection of water treatment technologies, the Water Solutions Sustainability Navigator will help users better understand the interconnection of sustainability-driven choices and the cost of operations,” said Jeroen Bloemhard, Vice President and General Manager, DuPont Water Solutions.

Currently, the tool allows users to input four different water treatment technologies – reverse osmosis (RO), ultrafiltration (UF), ion exchange resins (IER) and membrane bioreactors (MBR) – used alone or in combination. www.dupont.com

Gessner Adds Activated Carbon to Electrostatic Air Filter Media

GESSNER now offers their Alphastar™ tribo-electric nonwoven and NeenahPure™ meltblown nonwoven with an activated carbon layer for pleatable and bag filters. These high-efficiency, electrostatic filter media can be developed meeting individual requirements from high efficiency filtration to standard requirements.

The activated carbon layer captures and neutralizes a wide range of impurities, including volatile organic compounds (VOCs), odors, and other contaminants. Depending on the customers’ needs GESSNER develops the activated carbon layers for each individual application.

Alphastar™ triboelectric filter media provides superior filtration performance with high dust holding capacity, low resistance to airflow, and high removal efficiency. The NeenahPure™ product range is their highly charged meltblown media solution for pleatable and bag filters in HVAC, air purification and air pollution control applications to provide clean indoor air for a better protection.

With a range from highest to standard efficiency, covering efficiencies from MERV 8 – MERV 16 (ASHRAE) and from ePM10 – ePM1 (ISO 16890) and the technical possibilities to customize the activated carbon layer as well as the particle layer, GESSNER engineers filter media tailored to the specific requirements of each customer. www.gessner-filtration.com

Cleanova Launches Groundbreaking Carbon Capture Filtration Tech

Cleanova recently announced the launch of its new filtration technology designed for carbon capture, utilization and storage (CCUS) applications. By capturing carbon dioxide (CO2) from various sources, CCUS is set to play an important role in achieving global Net Zero emission targets.

To ensure that CO 2 is free from both solid and liquid contamination, filtration technology is used to separate the captured gases from each other.

“Filtration technology plays a pivotal role at every stage in the carbon capture process, from the arrival of the feed gas, through chemical absorption to final storage and transportation,” explained Chris Nixon, Engineering and Products Director at Cleanova.

Each filtration solution has to be tailored to specific conditions such as CO 2 concentration, the nature of the emission source, the presence of other contaminants, temperature and pressure.

The Cleanova.C-CLEAN technology suite includes UNIQ-MAX High Capacity Filters, which prevent absorb plugging by removing high quantities of suspended particles from feed gases.

This is in addition to liquid/gas coalescers to ensure solvent purity, activated carbon filters to eliminate hydrocarbons and contaminants and oil mist eliminators to ensure clean exhaust air, stated the company. www.cleanova.com
