Facility Details »

$109 / dry ton, Amazing!
In 2004, the City of Bowling Green, Ohio, installed Ohio's first TPS ThermAer Process expanding the plant capacity from 6 MGD to 10 MGD. This energy efficient process offered superior solids reduction and an odor-free operation. Doug Clark, Water Pollution Control Superintendent, calculated 2009 treatment costs at a remarkable $109 per dry ton. In addition, 38% total solids are coming off the centrifuge.

Speedway, IN - The TPS SNDR following anaerobic digestion shows exceptional results. Preliminary average results since May 2012 start up are: ammonia filtrate concentration of 14 mg/L plus an additional volatile solids reduction of 38%.
