Resource Recovery

In recent decades, the wastewater sector has moved away from the idea of wastewater treatment plants as waste disposal facilities, instead envisioning these plants as water resource recovery facilities (WRRFs). WRRFs can produce clean water, recover nutrients (such as phosphorus and nitrogen), and potentially reduce fossil fuel consumption through the production and use of renewable energy.

Quality of Biogas Derived from Wastewater Solids and Co-Digested Organic Wastes: A Characterization Study

$156,988
Completed

Project Highlights

Co-digestion allows utilities to beneficially reuse organic matter and produce renewable energy. However, adding organic matter can result in unintended consequences to facility operation, such as digester foaming, sludge dewaterability, and odor. This project developed the scientific information needed to...
