Due to increasing public interest in water purity, and projected sharp increases in energy costs in the near future, Wastewater Treatment Plants (WWTP) are becoming interested in optimizing their activated sludge process to reduce operating costs, and stabilize process operation. This paper presents an activated sludge process evaluation that describes how aeration energy savings of 23 to 45% and process stability can be obtained by controlling the Solids Retention Time (SRT) and Dissolved Oxygen (DO)

Keywords: Aeration Control; Energy Savings; Process Optimization
