Beijing Wastewater Treatment Plants Use THK 600 Thickeners

Centrisys Corp. announced that wastewater treatment plants in Beijing, China, are installing 23 of Centrisys' THK 600 Thickeners. These plants serve the largest municipal area of the country. The installation is part of a three-plant project aimed at increasing overall plant efficiencies by lowering energy consumption and eliminating polymer costs while maintaining throughput. 

Beijing Drainage Group's purchase of the THK 600 units and installation plan were based on test results from the GaoBeiDian wastewater treatment plant (WWTP) in October 2012. The series of installations will be completed in three phases at three separate plants that partially comprise Beijing’s 16 municipal wastewater treatment plants:

• Five THK 600 units were installed at the DingFuZhaug WWTP in early 2016, which is a new plant with an 80 mgd daily flow capacity.
• Eight THK 600 units were installed in August 2016 at the ZhengWangFen WWTP, another new plant with a 200 mgd daily flow capacity.
• Ten THK 600 units have been purchased for future installation at GaoBeiDian WWTP, the largest individual plant in China with a 264 mgd daily flow capacity.

The THK 600 installations are the first-of-their-kind in China. The THK technology was chosen due to its high thickening efficiency, low energy consumption, and high capacity and polymer cost savings.

“Centrisys has been setting a standard for effective solid separation solutions for nearly three decades, providing efficiency and cost-saving benefits to plants across North America,” said Michael Kopper, CEO and founder of Centrisys. “We’re proud to bring our thickening innovation to help municipalities in Beijing and other global markets to accelerate their plant efficiencies with industry-leading solutions that bear out environmentally-conscience and cost-effective results.”

The THK Thickening Centrifuge was first engineered by Centrisys in 2013. The THK 200 breakthrough earned an Innovative Technology Award from the Water Environment Federation. 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 earn a return on investment of 2.5 years.
