Technology produces superior biogas feedstock

By Staff | April 03, 2014

Rochester, N.Y.-based ClearCove Systems Inc. was awarded funding from the New York State Energy Research and Development Authority to demonstrate a new wastewater treatment system at the Ithaca Area Wastewater Treatment Facility in the Finger Lakes, and the Nott Road Wastewater Treatment Facility in Guilderland. NYSERDA has provided $300,000 for the projects, and ClearCove is contributing an additional $300,000.

ClearCove has invited a screening technology that enhances settling techniques that water treatment plants typically use to process sewage. The patented process reduces energy use by removing more organic matter from the waste stream before it undergoes aeration or secondary treatment. As an added benefit, the system creates an organic byproduct that can be used for anaerobic digestion. ClearCove studies have demonstrated that organic matter captured by its primary treatment system and used in anaerobic digestion generates three times more biogas than organic matter typically taken from secondary treatment does.
