Making WavesKoch Membrane to Launch NewHollow Fibre UF SystemKoch Membrane Systems (KMS) willintroduce TARGA® II HF, a new hollow-fibreultrafiltration membranesystem, in June at ACE11, the AmericanWater Works Association’s 130th AnnualConference and Exposition according toa press release.The TARGA II HF system offers a costeffective,safe, high-quality water solutionfor a variety of ultrafiltration applications,from drinking water to seawaterpretreatment, industrial water treatment,and tertiary wastewater treatment. Themembrane element features a robust PESmembrane which, combined with optimisedcartridge and rack design, resultsin one of the smallest footprint productson the market. The fibres are ideally suitedto meet drinking water requirements andprovide 4-log virus removal.The cornerstone of the TARGA HFsystem is intelligent process controls tohandle variations in water quality andflow with minimal operator intervention,reduced chemical use, and less energy.“In addition to optimised PES basedmembrane chemistry to reduce membranefouling and improved module design toimprove product robustness, TARGA HFcomes with a state-of-the-art intelligentcontrols system. The intelligent controlsystem was developed after extensiveprocess testing with TARGA HF and allowsusers to handle variations in feed waterquality and flow variations with minimaloperator inter vention while reducingoverall chemical and power consumption,”said Manny Singh, KMS Vice President ofTechnology Product Management.KMS will also display its leading MBRsolution, the PURON submerged membranemodule, at ACE11. PURON modulesoffer significantly lower life-cycle costsdue to a single-header design that providesbetter solids management in themodule, braided fibres to reduce the riskof fibre breakage, and highly effective airscouring that virtually eliminates sludging.PURON technology produces high-qualityeffluent that can meet stringent waterreuse and recycling requirements while itscompact design significantly reduces thetreatment system footprint and installationcosts.New Food-Contact and Drinking WaterCompliant ResinDSM has introduced its latest compositeresin – Atlac® 5200 FC -developed specifically for use incomposite applications that have contactwith food and water. Officially launchedat last week’s JEC show in Paris, this newvinyl ester resin is unique in that it is fullycompliant with the European regulationson food contact and made in line withcommonly accepted Good ManufacturingPractices for the Food Industry. The resinis therefore suitable for use in a variety ofcomposite applications such as tanks andpipes that are intended for contact withfood and potable water.Typical end use applications includepotable water transport networks, watertreatment installations, desalinationplants, and in-plant piping and storage vesselsin food processing industries. Atlac®5200 FC resins can be converted in standardmanufacturing processes including filamentwinding, infusion and hand lay-up.The process-ability is as robust as withconventional vinyl ester resins for makingpipes, vessels or tanks.In the coming years, health, safetyand environmental regulations as well aslegislative measures are likely to becomemore stringent, with the immediate resultthat the demand for high quality and safeto-usestorage tanks and piping is set togrow.Through its excellent anti-corrosionand heat resistance properties Atlac® 5200FC resin enables the manufacture of compositecomponents that are long-lasting,even in hostile environments. For plantoperators this means continued processoperation, reduction of maintenance, andconsequently low cost of ownership. Inaddition the use of composite materialswill allow for optimising design and forintegration of individual parts.BIO-VASE Treats Rivers, Lakes,Harbours and LagoonsBIO-VASE is an ecological product,which breaks down organicsludge, by contrast to traditionalmethods, which only dislodge it. Byeliminating the organic material presentit consequently re-establishes the balancein the ecosystem. It also allows fora significant reduction in the quantity ofsuspended matter, which improves theclarity of the water expanse treated.B I O -VA S E co nsis t s o f a p owdernon-soluble in water, with variablegranulometry, and is supplied in 25kgbags. The treatment principle involvesthe provision of microorganisms whichmultiply and break down the organicpart of the sludge. BIO-VASE allowsfor a considerable reduction in the levelof organic sludge in ponds, rivers andcanals. The many examples of use ofthe product indicate a reduction of upto 50% in sludge volume.One of the main strengths of BIO-VASE, in addition to its attractive priceas compared to other methods, is itsextremely high user-friendliness. Indeed,it does not require any mechanicalequipment and does not cause damageto areas surrounding water expanses.28 WaterMalaysia
