“Plant staff found that process improvements are possible by proper selection of process parameters such as D.O. and SRT and automating control of these parameters using commercially available software such as OPTImaster™, DOmaster™ and SRTmaster™ (Ekster and Associates Inc). Results showed that process optimization and automation reduced energy usage by 25%, polymer usage by 25% and improved process stability.”

Cordel Samuels, Area Supervisor (currently Plant Manager), Toronto WWTP

“A significant reduction of polymer (up to 50%) was observed. The control system considerably improved stability of the activated sludge system process by reducing variability in solids age and drastically improved thickening of waste sludge. In addition, the system was very reliable due a sophisticated control algorithm built in the controller.”

Stephen Smith, Senior Operator, Topeka WWTP

“SRTmaster™ helped to improve water quality, and plant effluent became compliant with NPDES.”
