SHOWCASE CERAMIC MEMBRANE AT HEART OF NEW BIOREACTOR An above-ground bioreactor that uses a ceramic membrane invented by scientists at the Australian Nuclear Science & Technology Organisation has been successfully commercialised and sold to the private sector. The Australian government announced on 22 March 2010 the sale of the intellectual property for "BioGill" technology to Australian clean-tech company, BioGill Environmental Pty Ltd, a manufacturing company based in Sydney. BioGills are specially built bioreactors that provide ideal The Danfoss APP RO high-pressure pump range advantages. Energy transfer is up to 91%, providing system energy savings of up to 60% compared to configurations with no energy recovery. Its simple installation is not just due to the smallest footprint available in isobaric ERD, but also because the iSave design combines three components into one. The rotary isobaric pressure exchanger, electric motor and high-pressure positive displacement pump are all joined in one compact unit. QUA UF/EDI PRODUCTION RECEIVES ISO CERTIFICATION Pennsylvania-base QUA®, a developer of electrodeionization (EDI) and ultrafiltration (UF) products, has received ISO 9001:2008 Certification, attesting that its manufacturing facility conforms to this internationally recognized quality management system standard for the manufacture, supply and after-sales service of its membrane products. ISO (International Organization for Standardization) is the world's largest developer and publisher of International Standards. QUA's products include CE-certified FEDI® fractional EDI technology, and Q-SEP® hollow-fiber UF modules. The company manages the entire lifecycle and manufacturing chain of these products from initial concept to manufacturing in an in-house state-of-the-art membrane manufacturing facility with continuous monitoring to maintain consistent quality. Earlier this year, QUA was awarded NSF/ANSI 61 Certification by NSF International for the manufacture of its Q-SEP UF range. COATING PREVENTS BIOFILM ON FILTER ELEMENTS FouleX is a new development from Boll & Kirch's research and development, designed to prevent the build-up of biofilm contamination on filter elements. Two Bollfilter 6.18 Automatic Filter Systems were installed accommodation for microbes. By providing the perfect home, above ground and surrounded by oxygen, the microorganisms grow and flourish. BioGills are manufactured using a Nano-Ceramic Membrane™ incorporated into a bioreactor that effectively operates as both a "stomach" and a "lung". Bacteria and other microorganisms "eat" waste out of the water and "breathe" air to grow and multiply. The microorganisms develop on membranes folded to form a series of "gills". Wastewater travels down between these "gills" and oxygen is freely available, providing the ideal environment for the microbes. The result is that each BioGill treatment core has an enormous biomass loading, delivering a treating biomass of 10 to 15 times that of conventional biological wastewater treatment systems. This provides accelerated treatment and uses considerably less energy than conventional wastewater treatment systems. ARKEMA'S ARIZONA DEBUT HERALDS WATER-TREATMENT MEMBRANE PUSH The presence of Pennsylvania-based Arkema Inc, part of France's leading chemical producer, at the AWWA/AMTA conference in Arizona in February 2012 was one of the first moves along its development expansion into the water treatment industry. The company is hoping that its Kynar® polyvinylidene (PVDF) fluoride resins, as well as its foamed extruded products, will find increasing application in the membrane water business. To this end, Arkema in January 2012 appointed business development engineer Sean Stabler to oversee this new development. A new Arkema product, Kynar 2620 FC, has been developed for used in applications where a lighter weight, softer and more flexible PVDF is required. at the WAG Water Treatment Plant in Germany to provide primary protection for the ultrafiltration membrane plant. However, due to the presence of manganese bacteria, a biofilm formed on the filter elements after just three month's operating time. As a result, the normally self-cleaning filters had to be manually cleaned - washed inside and out with a high-pressure cleaner and decontaminated with an acidic cleaning agent. The problem was solved by the application of FouleX coating to the filter elements which, after three month's normal operation, were checked and found to be completely free from biological growth. HIGH PERFORMANCE ANTISCALANT LAUNCHED AT ARIZONA EVENT A new high performance antiscalant, SpectraGuard™ 350, was launched on 27 February 2012 by Professional Water Technologies, the H2O Innovation business unit. The announcement was timed for the AWWA/AMTA Membrane Conference in Arizona, which started on 28 February. SpectraGuard™ 350 has been developed to provide a much higher level of protection and control over inorganic and colloidal species in water-reclamation plants and brackish-water reverse- osmosis RO desalination plants. Recently certified for use to ANSI/NSF Standard 60, SpectraGuard™ 350 is already in use in a major water- reclamation plant in Arizona. PWT and H2O Innovation's sales teams have started to market the product to their customer May-June 2012 | Desalination & Water Reuse | 37 |
