Particle Size Separation Implications on COD Removal before BNR: A Case Study
Biological Nutrient Removal (BNR) can be an attractive option for upgrading an existing system to meet nutrient removal requirements when the plant is in need of upgrading the secondary system for other reasons, such as a hydraulic capacity increase. BNR operation requires carbon for denitrifying and phosphate accumulating organisms. Conversely, primary removal of total suspended solids (TSS) and particulate biochemical oxygen demand (BOD) is attractive for maximizing treatment capacity while minimizing energy consumption in the secondary system; however, excessive removal of BOD could potentially interfere with BNR operation. In this study, the removal of particulate BOD by a continuous belt, fine mesh sieve installed at a BNR plant was examined for its effects on BNR operations. Significant TSS and BOD may be removed without affecting BNR efficiency when particle size distribution of influent wastewater and its relation to biodegradable chemical oxygen demand (COD) are considered.
