ABB manages energy at intelligent wastewater plant in Germany

By District Energy posted 08-07-2023 17:08




ABB reported July 13 that its Ability Energy Management and Optimization (Optimax) solution is at the heart of an intelligent-energy wastewater treatment plant in Schwarzenbruck, Germany, started last September by the Schwarzachgruppe sewage association.

The new wastewater treatment plant is an environmental innovation showcase that automatically balances energy-consumption and production, so an external power supply is required only rarely. Thanks to this energy-intelligent concept, it’s estimated that the plant can save about 300 tons of CO2 per year.

Optimax enables the plant’s potential energy efficiencies to be exploited and existing energy generation and storage options to be networked, controlled and optimized. These facilities include a hydroelectric power plant in the wastewater treatment plant outlet, photovoltaic solar panels, two combined heat and power plants using sewage gas, electricity storage in batteries, sewage gas storage, heat storage as hot water, and coupling various storage units for continuous provision of thermal or electrical energy.
