Co-Digestion of Organic Waste-Addressing Operational Side-effects

This study evaluated operational side effects associated with co-digestion of high strength waste (HSW) and wastewater solids (thickened primary sludge and thickened waste activated sludge) at water resource recovery facilities (WRRFs). The two goals of this study were to evaluate co-digestion facility design, performance data, and operation and maintenance issues at five WRRFs and to evaluate the impacts of co-digestion of HSW on methane production, sludge production, and nitrogen and phosphorus concentrations in recycle streams. Recommendations for better process control during co-digestion are included. Research Partner: New York State Energy Research and Development Authority (NYSERDA). Published by WE&RF in 2017.

This study was a originally funded in cooperation with WERF as project ENER9C13 and was managed by Lauren Fillmore MS and Kenan Ozekin, PhD.
