Nutrient Removal Evaluation

Sherman, Texas

PECI identified and evaluated nutrient removal process configurations for a 16 MGD municipal wastewater treatment plant.  Unit processes, configurations and preliminary costs were determined for chemical phosphorous removal and biological nutrient removal (BNR) processes.  Three alternatives for BNR were evaluated as part of the project.  Capital and operating costs for one alternative for BNR, Anaerobic/Anoxic/Aerobic, along with upgrading the aeration system, chemical phosphorous removal and side stream treatment of the supernatant stream from solids handling were also determined.
