NEWS said Jonathan Lash, President WRI. ‘WRI hopes that investors will begin ‘‘pricing in’’ these under-appreciated risks, driving investments to support more hydrologically efficient designs and technologies.’ From the perspective of General Electric and Goldman Sachs, the Water Index will enable each firm to better advise customers and clients on water-related risks and opportunities. ‘From a technology perspective, technology to enable water reuse and mitigate risk already exist,’ commented Heiner Markhoff, President and Chief Executive Offficer, Water & Process Technologies, GE Power & Water. ‘Advanced technology, such as membrane and water-efficient cooling systems, are available to manage the risks once these are identified and measured, which is what the Water Index aims to do.’ Tracy Wolstencroft, who is global head of environmental markets for Goldman Sachs, added: ‘Many environmental factors, including water, pose both challenges and opportunities for investors and businesses. The Water Index will provide valuable insights that can inform investment decisions and will help identify new opportunities across sectors and geographies.’ Contacts: World Resources Institute, 10 G Street, NE (Suite 800), Washington, DC 20002, USA.

Water purification device aids trace elemental analysis

M

illipore Corp, a US-based provider of technologies, tools and services for the global life science industry, has announced the availability of the Q-POD Element unit. Designed for use with the Milli-Q Integral and Milli-Q Advantage systems, available from the company, the device delivers ultrapure water with extremely low levels of elemental contamination (single ppt or sub-ppt level) for laboratories performing trace and ultra-trace elemental analysis. By eliminating problems because of backgrounds with high elemental contamination, water produced by the Q-POD Element device

can help scientists achieve greater sensitivity and reproducibility in their work, explains Millipore. Equipped with a foot-switch for hands-free water delivery, the Q-POD Element unit is ideal for use in a Class 1000 clean-room environment. It supplies water in volumes required by the user (up to 1.5 l/min), which avoids a water storage as well as the associated contamination risks.

Siemens’ MBR helps China restore Taihu Lake’s water quality

S

iemens Water Technologies has commissioned a wastewater treatment system for the Wuxi Xincheng Plant in China’s Jiangsu Province. An upgrade to the existing wastewater treatment plant, the system includes Siemens’ Membrane Biological Reactor (MBR) system. It is producing 30 000 m3 (7.9 million gallons) of high-quality effluent per day, which meets or exceeds the national discharge standard of Class I-A – enabling the treated water to be safely discharged into Taihu Lake. The MBR system at Wuxi Xincheng combines conventional biological treatment processes with membrane filtration using the firm’s Memcor membranes. The company says that it can significantly reduce both nitrogen and phosphorus content in the treated effluent by breaking down the organic nutrients and filtering the solids. The MBR system requires an installation footprint that is about 75% smaller than that needed by conventional technology – which is important for existing plants with limited space. The technology has been applied to more than 70 facilities around the world, says the company. Located in the highly developed and densely populated Yangtze River Delta, Taihu Lake has been increasingly polluted in recent years. As part of its efforts to clean up the lake, Jiangsu Province set out to improve sewage treatment capacities in cities surrounding the lake area. The MBR system will enable the Xincheng plant to better serve over 100 high-tech enterprises in the Wuxi New District’s industrial park, which has experienced a 20–25% annual increase in wastewater.

In Brief H2O Innovation awarded new contracts and adds representatives in the USA Canadian water-treatment technology company H2O Innovation Inc has recently landed contracts worth a total of C$2.2 million. These contracts will see the firm designing, manufacturing and delivering custom-built water-treatment systems for the production of drinking water by reverse osmosis, water reuse and the treatment of wastewater. Some of the contracts will also see the firm supplying process equipment and parts. H2O Innovation has also signed agreements with three new sales representatives in the USA for its wastewater treatment technology, including its patented Bio-Brane MBR for water reuse applications. Memstar supplies membranes for MBR wastewater treatment plant in China Singapore’s Memstar Technology Ltd has been awarded a contract worth RMB60 million to supply membrane products to the Guangzhou Municipal Government for its wastewater treatment plant. The facility, which has a capacity of 100 000 m3 per day, is based on membrane bioreactor (MBR) technology and when completed in June 2010 will be one of the largest MBR plants in China. Norit–Greentech wins contract for wastewater reuse project in China A joint venture involving Norit NV and GreenTech Engineering Co Ltd had been awarded a contract covering the design, procurement, installation and start-up of the Qinghe Municipal Wastewater Reuse Project in Beijing, China. This project, which is believed to be the single largest one of its kind (180 000 m3 per day) in China, is part of the Qinghe wastewater reuse plan, developed by the Beijing Drainage Group. The system is based on Norit X-Flow XIGA ultrafiltration membrane technology and GreenTech’s CMSCompact modular skids. The project is worth about RMB75 million. A.O. Smith concludes purchase of water treatment business A.O. Smith (Shanghai) Water Treatment Products Co Ltd has concluded its purchase of Tianlong Holding Co Ltd’s watertreatment business (see Membrane Technology October 2009, page 2). A.O. Smith holds 80% of the newly formed company, which is considered to be a wholly owned foreign enterprise under Chinese law. A.O. Smith (Shanghai) will supply reverse osmosis water purification products to the residential and commercial sectors in China and export to markets worldwide.
