BEIJING, China – The Beijing Drainage Group in China has purchased 23 THK Thickeners from US company Centrisys Corporation to install across its 16 wastewater treatment plants (WWTP) in Beijing, China.
The deliver is part of a three-plant installation project aimed at increasing overall plant efficiencies by lowering energy consumption and eliminating polymer costs, all while maintaining throughput.
The units were purchased based on test results at theGaoBeiDian wastewater treatment plant in October 2012.
The series of installations will be completed in three phases at three separate sites that comprise part of Beijing’s 16 municipal wastewater treatment plants, including the DingFuZhaug WWTP (364,000 m3/day), the ZhengWangFen ( 910,000 m3/day) and GaoBeiDian WWTP (1.2 million m3/day).
Centrisys Corporation said: “THK Thickeners help decrease polymer consumption and increase capacity with little to no polymer required, allowing the average plant to save $140,000 per dry ton of solids in the waste activated sludge thickening process, and a return on investment of 2.5 years.”
