Catalyzing Anaerobic Digestion in Wastewater Treatment Plants 

The ClearCove Harvester™ technology was demonstrated at the Ithaca Area Wastewater Treatment Facility (IAWWTF) under New York State Energy Research and Development Authority (NYSERDA) Program 2722 “Towards Net Zero Energy in Wastewater Treatment”.

Abstract from the NYSERDA Report

The following report abstract highlights ClearCove’s technological leadership from both an energy production and energy savings standpoint. The Company’s patented technology is able to elevate anaerobic digestion to previously unseen levels of performance. The full report can be viewed by clicking on the icon at the bottom of this page.

“Conventional primary treatment typically removes less than 25-35% of the organics at the head of the wastewater treatment plant. The ClearCove Organics Harvester (OH), an innovative process piloted at the Ithaca Area Wastewater Treatment Facility (IAWWTF), proved that it removes the majority of organics in the primary stage.

In the demonstration project, increased biogas generation from the pilot system was realized and anticipated energy savings associated with secondary treatment upon installation of a full-scale system were calculated. This project was validated by measurements of the removal capabilities of the OH pilot in combination with pilot-scale anaerobic digestion. An increase of methane production from primary sludge by 240-520% was shown and a 52% reduction of energy associated with secondary aeration upon installation of a full-scale system was calculated. Should a full-scale system be installed at the IAWWTF, total methane production is anticipated to increase by 180-320%, depending on the valuation matrixes and that the IAWWTF would be capable of producing more energy than it consumes.”

“This demonstration project would not have been possible without the assistance and support of Dan Ramer and the operators/staff of the IAWWTF and O’Brien & Gere Engineers; Kathleen O’Connor of NYSERDA; and the members of the Project Advisory Committee, including Jason Turgeon, Lauren Fillmore, Rich Lyons, Ralph Eschborn, and Jim Fitzpatrick. We also sincerely thank Mayor Svante Myrick, his staff, and the citizens of Ithaca, NY for their hospitality.”
