Optimising the operating cost of wastewater systems

Operating costs of wastewater systems concentrate in three areas: power, chemicals and labour. Optimising each can yield significant savings.

Dosing chemicals to actual load, using variable-frequency drives for blowers and automating operation reduces waste and stabilises effluent quality.

Periodic maintenance and a skilled operating team are key to efficient, durable and compliant system performance.

A simple yet effective solution is installing flow meters and online sensors to monitor key indicators such as pH, DO and TSS — enabling timely adjustments that avoid chemical and energy waste.
