Characterizing Mechanisms of Simultaneous Biological Nutrient Removal During Wastewater Treatment
Abstract
Simultaneous biological nutrient removal (SBNR) is the removal of nitrogen and phosphorus in excess of that required for biomass synthesis in biological wastewater treatment systems where there are no defined anaerobic or anoxic zones. This report identifies factors affecting the relative contributions of three mechanisms responsible for SBNR: bioreactor macro-environment, floc micro-environment, and novel microorganisms. Also of note is the report’s outline of computational fluid dynamics and its potential application in complex biological wastewater treatment systems. It is hoped that this research will lead to improved design and control of future BNR processes with associated cost savings. Published by WERF. 100 pages. Soft cover.
