Hyflux and Ondeo awarded PUB contract The Public Utilities Board (PUB) of Singapore has awarded a contract for a build, own and operate desalination plant to Singspring, a consortium comprising Hyflux Ltd and Ondeo. To be built in Tuas, Singapore, the new plant, which will be capable of producing 136 000 m3 desalinated water a day, is scheduled to start supplying water during the second half of 2005. It will use reverse osmosis. Hyflux is taking a 70% stake in the consortium, while Ondeo will assume the balance. With this increased stake, the Hyflux Group says that it is expected to win major contracts from the engineering, construction and procurement contractor for the project. Most of the contract value will lie in the membrane systems that it is supplying. These will be built locally using its proprietary membrane technology. Revenue from this project will be realized over a period of 2.5 years. Commenting on this award, Ms Olivia Lum, Hyflux Group chief executive officer and president, said: “This is our biggest project to date. It is a strategic project for us and so it is logical for us to take a majority interest. It will position us to be a strategic player in large municipal projects in Singapore and beyond.” For more information, contact: Hyflux Group, 40 Changi South Street, 1 Singapore 486764.

GEA offers spiral-wound RO plants In the USA, GEA Filtration has introduced sanitary reverse osmosis (RO) plants in a 20 cm (8 inch) spiral-wound configuration. The company says that this new sanitary design offers the same modular, cost-effective plant con-
struction and operating advantages as its spiral plants with a smaller diameter, but offers the added advantages of a more compact design, lower capital cost, reduced membrane replacement costs and no adverse effects on plant cleanliness or sanitation. The membrane area is delivered in the larger 20-cm (8-inch) diameter sanitary spiral-wound format, and it is housed in 20-cm (8-inch) sanitary vessels. It is this increased membrane packing density that creates the compact design, saving valuable floor space, says the company. Operating costs are further reduced by the improved compact design and reduced plant hold-up volume. This results in a reduction in water consumption, and associated wastewater treatment costs, as well as a reduction in the consumption of clean-in-place chemicals. The plants are constructed to 3A sanitary standards for compliance with US Department of Agriculture and local regulatory health agency requirements. According to GEA, exhaustive cleaning and sanitation trials on several commercially delivered plants have verified that they operate with no compromise to cleanliness and sanitation. GEA says that with several plants now delivered and in operation, and several more in the pipeline, sufficient demand has been created to ensure that membrane elements in the 20-cm (8-inch) sanitary configuration are widely available from a number of manufacturers and can be supplied directly from the company’s stock.

Electropure granted ionexchange patent Electropure Inc of Laguna Hills, California, USA, has been granted a US Patent for what it claims is a novel process that is used to make improved ion-exchange membranes, an integral part of its
electrodeionization (EDI) water purification technology. The patent (number US 6503957) describes a low temperature method for making polypropylene-based ion-exchange membranes, which enable the efficient removal of impurity ions like sodium, chloride and silica from water. Electropure says that its process for making membranes is also environmentally friendly, using no solvents of any kind, and it is ideal for systems that go into EDI pharmaceutical applications. Michael Snow, general manager of the EDI subsidiary, says that this patent enables Electropure to offer high quality EDI products, and the patented process lets the company manufacture ionexchange membranes continuously at a reasonable cost, and with strict quality control. Electropure designs, manufactures and markets proprietary water purification equipment and laserbased technology for detecting and identifying microorganisms in real time.

Georgia and DND select Zenon technology Zenon Environmental Inc’s technologies are set to be used in a wastewater treatment project in Georgia, USA, and by Canada’s Department of National Defence (DND). Zenon has been selected by Gwinnett County to supply its patented ZeeWeed membrane technology to F. Wayne Hill Water Resources Center in Georgia. The company negotiated an agreement with the county for around C$30 million, and it expects to receive the final purchase order by July 2003. The Gwinnett County F. Wayne Hill Water Resources Center is a water reclamation and processing facility that is located just north of Atlanta, Georgia. Plans are under
