Abstract

This research examines a new side-stream enhanced biological phosphorus removal (EBPR) process (S2EBPR) that involves a side-stream anaerobic biological sludge hydrolysis and fermentation reactor to address the common challenge in EBPR related to weak wastewater influent and to improve EBPR process stability. The overall goals of the study were to examine the fundamental mechanisms involved in the S2EBPR process and to develop criteria for effective design and operation of the process. To achieve the objectives, the research team conducted a survey of data from full-scale S2EBPR facilities, simulated side-stream reactor batch testing, performed full-scale pilot testing with side-by-side S2EBPR and conventional EBPR processes, and developed an improved biological process model for S2EBPR.
