Siemens to Provide Wastewater Treatment Solution to help Chinese City Restore Water Quality inTaihu Lake.
Posted: Tuesday 7th October 2008
The Chinese city ofWuxi, in Jiangsu province, has selected Siemens to provide a solution to treat municipal waste water and help restore the water quality ofTaihuLake.
An important water source for 30 million people, the lake has been heavily polluted by municipal sewage and industrial wastewater. The solution from Siemens will include a Membrane Biological Reactor (MBR) system for the upgrading ofWuxiXincheng Wastewater Treatment Plant, one of the city’s three main wastewater treatment plants. The MBR system will treat 30,000 cubic meters of wastewater per day, and will play an important role in helping the city to treat more than 90 percent of its wastewater by 2010. The system is scheduled for commissioning at the end of 2008.
As part of its efforts to clean up Taihu Lake, Jiangsu province issued what is considered to be the strictest wastewater treatment standard in China. The province also set out to improve sewage treatment capacities in cities surrounding the lake area. The MBR system will allow the Xincheng plant to better serve over 100 high tech enterprises in the Wuxi New District’s industrial park, which has experienced a 20 to 25 percent annual increase in wastewater.
Siemens’ MBR system integrates Siemens’ innovative Memcor membranes and the conventional wastewater treatment process. This system can significantly reduce both nitrogen and phosphor in the treated effluent by breaking down the organic nutrients and filtering the solids. The MBR will enable the Xincheng plant to produce high quality effluent that exceeds the national discharge standard of Class I-A, and will allow the effluent to be safely discharged to Taihu Lake or meet local requirements for reuse water.
