About Us

TPS ThermaerThermal Process Systems was founded by experienced wastewater treatment professionals who understand first hand the complex issues of bio-solids processing and re-use. Frustrated by the compromises that were necessary with existing systems -- and the inability of these processes to meet industry demand -- they formed their own company focused exclusively on bio-solids management. Their first challenge: to develop a more reliable, more efficient process for the production of high quality bio solids. The result is the proprietary ThermAer process. ThermAer has been subjected to rigorous field-testing in full-scale operating systems, and pilot testing at various sites since 1995. It has exceeded every customer expectation. In addition to the proprietary ThermAer process, Thermal Process Systems has also established relationships with the most respected equipment manufacturers in the industry today. It is an unmatched combination, offering you complete systems integration, from retrofit to ground up installation and control.

$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%.
