Testing a Biofloc Model to Understand Dewatering and Solve Dewaterability Issues Related to Resource Recovery
Abstract
Many utilities have experienced poor dewaterability performance such as lower cake total solids and higher polymer demand with enhanced biological phosphorus removal (EBPR) and anaerobic digestion. A better fundamental understanding of bioflocculation during anaerobic digestion, and the interactions that occur during conditioning and dewatering to impact the critical outcomes of polymer demand, cake solids content, and capture efficiency is needed. This project seeks to address these important knowledge gaps and includes a final report that provides background, state of the science, and a summary of the research. A set of four fact sheets that examine different aspects of the dewatering process are also included. Published in 2020.
