Sustainability through Automation of Wastewater Treatment


As energy prices rise and effluent quality regulations tighten across the country, many wastewater treatment plants turn to automating their control strategy in order to maximize the efficiency of their existing process and equipment. Upgrading controls can help a WWTP consistently meet more stringent effluent requirements, thereby avoiding expensive equipment upgrades or discharge fines.

The goal of the pilot study was to improve energy efficiency by upgrading the mechanical equipment and the electrical controls in one treatment line, while maintaining the existing equipment and controls in the reference line in an effort to compare effluent quality and energy consumption between the lines.  The process controllers that were used to optimize the system include a cascaded DO control loop, most open valve control, and an ammonium feedback controller.
