Membrane InoCepÂŽ takes beer clarification to a higher efficiency level through ultrafiltration
Filtration is essential after the fermentation stage in beer production as it defines the final product, beer, with its unique colour, taste and most importantly stability. Filtration removes yeast cells along with by-products in the form of small solid particles present within the liquid product. Kieselguhr, also known as diatomaceous earth (DE), is a common batch filtering media used for such a purpose. However certain health risks are involved and precaution is needed when handling DE. Moreover, environmental laws have classified spent DE as hazardous waste making it mandatory for proper disposal. This increases both disposal and environmental costs. The solution: Microfiltration (MF) ceramic membranes. Replacing DE with ceramic membranes is a growing practise in the brewery industry.
Utilising this concept, Hyflux has developed a ceramic hollow fibre membrane, InoCep, capable of handling such an application. Known for their chemically inert nature, the ceramic material of InoCep allows it to be susceptible to operating beer clarification conditions of high temperature, pressure and extreme pH. Conditions of which, polymeric membranes are not suitable for. As well as separating hazy proteins for the end product to achieve a crystal clear appearance, the structure composition of InoCep such as membrane thickness and pore size also plays a critical role in retaining the flavour, nutrients and aromatic compounds present in beer.

To prove the superior performance of InoCep in beer filtration, Hyflux collaborated with a major brewery in Asia Pacific to conduct an on-site field test comparing beer production quality between a traditional DE system and MF system. Over a period of 6 months, beer brewed by these systems were subjected to many controlled variables where the effects of operating parameters, such as cross-flow velocity, filtration pressure, transmembrane pressure, backwashing, feed and temperature were studied. With such a comprehensive and rigorous field test, test results were found to have met the brewery’s high operating standards and requirements. Each brew output produced by InoCep that was compared against normal DE production met the exact requirements of yeast cell, bacteria and colloid removal while retaining the nutrients, clarity, colour and the unique bitter aftertaste of beer. Also beer brewed by InoCep systems are able to be stored for longer periods as the enzymes and microorganisms that cause chill-haze and micro-instability are reduced or eliminated. This removes the need for the addition of fining agents and for further downstream product sterilisation such as tunnel or flash pasteurisation. With the development of InoCep and the continuous advancement of ceramic membrane technology, Hyflux constantly strives to provide the benefits of higher product quality, lower process cost and process optimisation without compromising standards of the brewery industry.

Membrane Reverse osmosis seawater desalination projects true testimonials to the performance of KristalÂŽ One of the key drivers for an efficient and yet affordable reverse osmosis (RO) desalination system is an effective and reliable pre-treatment solution. To this end, utilising ultrafiltration (UF) technology and pioneered by Hyflux, Kristal membranes have proven to be an ideal product developed for such a purpose. Kristal membranes are specifically designed for RO pre-treatment that enhances the performance and extends the lifespan of RO membranes downstream.
The main constituent of a Kristal membrane is its specially formulated modified polyethersulfone (PES), which is more hydrophilic than other membrane materials like polyvinylidene difluoride (PVDF). This feature reduces fouling and increases its capability in handling streams of very high suspended solid organic contents.
Build up of particles over the surface of RO membranes (e.g. membrane fouling) can greatly reduce the performance of the RO process. This may lead to higher operating cost, lower plant productivity or even resulting in the breakdown of the whole system altogether. Thus extensive treatment is required upstream in any RO desalination process.
Kristalâ€™s unique asymmetric structure, an ultra thin skin built above a porous substrate enables both high water flux and mechanical strength. Kristal also eliminates conventional treatment processes that are land intensive. With a simple modular and compact design, Kristal offers a larger membrane area per unit volume at a smaller footprint size, hence lowering capital and installation costs. The Kristal series is also designed with a hollow fibre configuration that is capable of automatic backwash. At the end of the filtration cycle, the membrane surface is air-scrubbed by reversing the direction of water flow. This provides an efficient and effective mean of removing particulates and debris that cause membrane fouling. Without a pre-treatment system, directly processing raw seawater would result in a huge detrimental impact on the overall lifecycle and

In The News PM Lee speaks of Hyflux in national day rally speech
Although far away and out in the middle of nowhere, local companies with strong capabilities, like Hyflux, are building, expanding, gaining a march on their competitors. This statement made by Prime Minister Lee Hsien Loong during his National Day Rally speech exemplifies the culture with which Hyflux has adopted throughout its 20 years of installing turnkey projects; to break new boundaries in delivering safe drinking water to nations all over the world.
It is only through the pure amount of dedication and hard work that these men and women display, that this is made possible. As summarised by Mr Lee, “Because of this and other projects, Hyflux is doing well and still hiring engineers and it shows that there is still work to be done, provided we are prepared to rough it out and take the jobs which are available, which are good jobs.”
When asked by Mr Lee which project is the most challenging one he has ever faced, a Hyflux engineer simply replied, “Algeria”. Building the world’s largest sea water reverse osmosis desalination plant in Magtaa, Algeria, 22 Singaporean Hyflux employees currently working there face the true reality on a daily basis of being “far away” and “in the middle of nowhere”. Quartered into dorms and with only basketball and computer games to entertain themselves, the nearest town is a three hour drive away on bad road conditions, the project valued at US$468 million is nevertheless in full steam and is set to be completed by 2011.
