Title: Basics & Best Practices of Enhanced Bio-P Removal. What You Can and Cannot Control.
Speaker: Nick Barczewski
EBPR configurations have been successfully implemented in our industry for decades. These systems utilize the unique ability of polyphosphate accumulating organisms (PAOs) to assimilate large amounts of phosphorus and store it intracellularly as polyphosphate granules. Phosphorus then exits the treatment plant within the biomass wasted from the plant, enabling utilities to meet their effluent TP permits in an environmentally friendly and cost-effective manner.
The implementation of EBPR is relatively simple. PAO populations grow in EBPR plants by cycling the biomass through anaerobic and aerobic phases. The typical design approach is to add anaerobic selectors before the aerobic basins and develop EBPR from there. From a technology perspective, nothing more than small tanks, mixers, and perhaps ORP probes are needed for the anaerobic selectors. Nevertheless, there are variables involved in keeping a balanced cycle of phosphorus release and uptake carried out by PAOs that wastewater practitioners, operators, and technology providers cannot control. However, there are tools in the toolbox to help control some of these variables, either in the design phase or with operating strategies, to best optimize Bio-P removal efficiencies.
