Siemens Ltd. (China) will help Wuxi City in East China's Jiangsu Province recover the water quality of the Taihu Lake.

Siemens plans to supply a Membrane Bio-Reactor (MBR) system to the sewage treatment plants at Wuxi New Zone, an industrial development area, to expand its waste treatment capacity.

The MBR system is scheduled for trial run by the end of 2008. By then, 30,000 cubic meters of sewage will be disposed every day, thus helping Wuxi heighten urban centralized sewage treatment ratio to 90 per cent by 2010.

As an important water source for a population of 30 million, Taihu Lake was once fouled by industrial wastewater. To clean Taihu Lake, Jiangsu Province is now upgrading the sewage treatment plants in pan-Taihu cities.

MBR system will better service sewage treatment for 100 hi-tech enterprises in Wuxi New Zone, of which the sewage to be disposed increases 20- 25 per cent year on year.

MBR system combines membrane technology and traditional sewage treatment technology to greatly cut nitrogen and phosphorus in the water. The treated water can be discharged to river or recycled.

Siemens' MBR system also provides reclaimed water for Olympic Green, the Beijing Olympic Park.
