Koch MBR system chosen by Chinese city

A membrane bioreactor (MBR) using membranes supplied by Koch Membrane Systems (KMS) has been chosen for a wastewater treatment plant operated by Zhangjiagang JinGang Sewage Treatment, a state-owned entity which looks after all municipal plants for the Chinese city of Zhangjiagang.

Koch Membrane Systems GmbH was selected by Pacific Water Treatment Engineering Co Ltd (PWTE) to provide Puron® membrane modules for the new city wastewater treatment facility, in Jiangsu province, about 150 km northwest of Shanghai.

“After an extensive evaluation of the major membrane systems available on the market, we selected Puron submerged MBR modules because of their energy efficient design, the smallest footprint requirements as well as KMS’ engineering support during the enire project phase,” says George Shen, chairman of PWTE, a leading engineering company selected by the municipality to design and construct the MBR system. “We are also impressed with the strong, braided fibre, which reduces the risk of fibre breakage.”

The system is designed to handle an average flow of 25,000 m³/d, with peaks of up to 36,000 m³/d. Start-up is scheduled for early 2012.
