UV system is better than distillation Massachusetts-based Millipore Corporation has developed a water purification system which, it claims, offers numerous advantages over distillation. The company says that in contrast to this traditional water purification technique, its Elix ultraviolet (UV) system combines a number of purification technologies to provide users with clean water of consistent optimal quality. With distillation, specific ions and a number of organic molecules may be carried away with water vapor. As these contaminants distil or co-distil more easily than water, the quality of the purified water is compromised, says Millipore. The Elix system incorporates reverse osmosis, electrodeionization and germicidal UV lamp purification technologies that effectively remove ions, organics, particles and bacteria. The system produces pure water whose ionic quality for the majority of ions is equivalent – and in some cases superior – to the product water resulting from distillation, says the company. In addition, total organic carbon levels are significantly lower in the pure water produced by the Elix UV system than by distillation. The system is able to generate 10–4000 liters of pure water per day. The analytical-grade water that it produces meets the specifications for Type II water defined by ISO 3696/BS 3997. The water purification system uses easy-tochange cartridges and relies on an automatic cleaning process that does not require the use of a strong acid. Millipore says that users will also appreciate the system’s environment-friendly low water and electricity consumption that significantly reduces operating costs.

Gas filter makes bioreactors safer The new Emflon CPFR sterilizing grade gas filter from US company Pall Corporation is specifically designed for demanding fermenter or bioreactor applications by enabling manufacturers to use oxygen enrichment processes more safely. An increasing number of life-saving protein-based therapies are produced from cells that are grown in bioreactors using oxygen-enriched air for aeration. Pall says that while oxygen enrichment improves production yields and lowers overall processing costs, it can increase potential fire risks in sterilizing gas filtration operations. Enrichment techniques can lead to safety challenges because elevated levels of oxygen in bioreactor airflows can increase the risk of spontaneous ignition of conventional air sterilizing filter materials. The Emflon CPFR filter membrane is constructed from polytetrafluoroethylene (PTFE) — a widely used material that does not readily ignite. Additionally, the filter’s support and drainage layers are designed using special materials to minimize combustibility, compared with polypropylene that is commonly used in the construction in other gas filters. As worldwide demand for fermentation and biotechnology products continues to rise, manufacturers are increasingly turning to oxygen enrichment techniques to maximize the levels of the gas that reaches cells, thereby promoting growth. More traditional technologies such as mechanical agitation or airlifting could be inefficient or not appropriate for certain types of cells (for example, mammalian cells used for biotechnology drug products) because they are sensitive to shear. The Emflon CPFR filter has been evaluated by the Federal Institute for Material Research and Testing (Bundesanstalt für Materialforschung und -prüfung) in Germany, which routinely tests materials for usage in gaseous oxygen. The filter materials were subjected to pressure shock tests with 100% gaseous oxygen at about 1 MPa (10 bar g), at a temperature of 60°C. The institute concluded that

the filter’s materials had a high combustion resistance under rigorous testing, and were suitable for microbial and mammalian cell culturing applications using oxygen enrichment. The filter is also integrity testable using a Water Intrusion Test, says Pall. Contact: Pall Corporation, 2200 Northern Boulevard, East Hills, NY 11548, USA.

Hyflux sets up joint venture in China Hyflux Ltd, a water treatment company based in Singapore, has signed a joint-venture deal with Beijing Shouren Group to develop water treatment projects in China, according to a report by the Channel NewsAsia agency. The agreement was signed by the company’s subsidiary Hyflux Filtech (Singapore) Pte Ltd, Beijing Shouren Group Co Ltd, Beijing Zhouji Investment Co Ltd and Beijing Shouren Shidai Investment Consulting Co. The joint venture will make and sell water treatment equipment and components, provide technical consultancy, and support and undertake water treatment engineering projects. According to Hyflux, it opens up opportunities to participate in municipal water treatment projects in a region that is facing a shortage of water, and is host to the Olympic Games in 2008. Ms Olivia Lum, Hyflux Group Chief Executive Officer and President, says: ‘With our combined strengths, this joint venture is positioned to be a strong player in the municipal water market, especially in Beijing and other parts of northern China.’ Hyflux Filtech will hold a 26% interest in the registered capital of the joint-venture company.
