Our Process

Assured product quality - with no compromise.
With the patented ThermAer™ Process, you can achieve the results you want without compromising
your quality or cost objectives. The system delivers superior volatile solids and pathogen reduction
combined with extremely low odor in any reactor configuration - with assured EPA Class A and/or
exceptional quality certification.

Your system will be custom-engineered to fit your requirements exactly, whether you would like
to retrofit your existing basins - or integrate ThermAer into your new system. In typical
installations you will have the flexibility to batch or continuously feed the process daily, after thickening the feed material.

High temperature and intense mixing ruptures the cell walls of incoming waste stream
Foam production, an indication of degradation of proteins, controlled by hydraulic foam control cones Very low yield, an indication of high volatile solids reduction.


Greatly reduces the overall dewatering costs
Mesophilic conditioning and optimum pH provide suitable conditions for nitrification and denitrification. No external alkalinity required. Conditioning in SNDR™ decreases ammonia and, soluble COD while reducing overall chemical and polymer consumption.

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%.

GENENA, NEW YORK AND CONESTOGA-ROVERS & ASSOCIATES WIN A 2015 ACEC New York Platinum Award for their Digester and Grit Systems Improvements Project. This award, inclusive in the Waste and Storm Water category, will be presented on March 28, 2015 at the Waldorf Astoria, New York, NY! Congradulations to all those involved in making this project a tremendous success!

NEW YORK WEA 2016 Annual conference to showcase the Genena ThermAer installation.  On Tuesday, February 9, Eric Haslam of GHD and Robert Wooldridge of Thermal Process Systems, presented Conversion from In-Vessel Compost to Aerobic Digestion for Production of Class A Biosolids.  In addition, on Wednesday, February 10, Scott Crosswell and Howard Butler both of GDH presented Next Generation ATAD Philosophy and Start Up Lessons.  Click for Program
