GE MBR Technology to Help Restore Water Quality in China's Taihu Lake

System aims to achieve strict discharge standards and protect quality of China's third-largest lake

One of China’s fastest growing industrial cities has selected GE’s advanced wastewater treatment technologies to help restore water quality in Taihu Lake, the main water source for more than 30 million people in the region. The new Meicun Wastewater Treatment Plant, to be built in Wuxi, will be China’s first large-scale application of GE’s membrane bioreactor (MBR) technology and will demonstrate how the $10 million advanced treatment system can protect the nation’s water resources while promoting a strong economy.

The Meicun Wastewater Treatment Plant will play a key role in a province-wide effort to reduce the amount of chemical and organic wastes discharged to Taihu Lake. The first phase of the plant, capable of treating up to 30,000 cu meters (7.9 million gal) of water per day, will be rapidly completed and is scheduled to be operational by the end of 2008. The modular system will be expanded in stages to a treatment capacity of 100,000 cu meters (26.4 million gal) of water per day, making it one of the largest MBR treatment facilities in the world.

“GE’s advanced membrane system will ensure that this plant will consistently meet the strict new wastewater treatment standards established by the government and will help protect the water quality in Taihu Lake, an important source for millions of people,” said Xue Yuanshui, general manager of Wuxi Gaoxin Water Co., Ltd. “We are very proud to be among the first in China to show the important role that membrane technology will play in the responsible and sustainable management of our water resources.”

“GE’s success in Wuxi further demonstrates the capabilities of our broad portfolio to help China overcome its water and wastewater treatment challenges,” said Weifang Zhou, president of Greater China, GE Water & Process Technologies. “We will continue to invest in our nation-wide project delivery and support networks to fully support China’s industries and municipalities in balancing their economic and social goals with environmental objectives.”

GE’s ecomagination-certified MBR system combines selected microorganisms and ZeeWeed ultrafiltration membranes to breakdown organic nutrients and filter solids from wastewater. The systems produce high-quality effluent that can be safely discharged to Taihu Lake or reused for industrial applications, irrigation or aquifer recharge.
