Energy-efficient wastewater treatment

The amount of energy consumed in wastewater treatment plants across the world is estimated at 1-3% of global energy output. Modern utilities are consuming between 20 and 45 kWh per population equivalent connected. At the same time there is great untapped potential to generate energy from waste. Read on to learn how wastewater treatment plants can tackle increasing energy prices, scarcity of resources, and tightening regulations, while maintaining stable and future-proof operations.

How to reduce energy consumption in wastewater treatment

Learn how municipal wastewater treatment plants can use innovative technology to optimize energy-intensive processes.

Less is more

The most energy intensive part of wastewater treatment is the biological process. One way to tackle that problem is to feed the bacteria less by increasing the primary treatment load through digitally-enabled optimization. Settling more primary solids in the primary treatment step reduces the load for the aeration process. That lowers overall energy consumption, leaving the easily degradable COD for biology, which can also increase biogas production.

Sludge treatment and phosphorus removal are other areas with great potential for energy savings. A powerful combination of chemistry, data analytics and automated chemical dosing optimizes process efficiency – also in highly variable conditions.
