Wastewater treatment is the most energy-intensive business of Berliner Wasserbetriebe (BWB). Every year BWB needs the same amount of energy for this as a city with approx. 280,000 inhabitants. This electricity is a huge cost factor. Smart load management can help to use energy efficiently, reduce electricity costs and stabilise the utilisation of the network. The Münchehofe sewage treatment plant was selected as a pilot plant of BWB for the introduction of load management. The plant was opened in 1976 and has a cleaning capacity of 42,500 m³/d in dry weather. The energy-intensive treatment is carried out by mechanical and biological wastewater treatment. The sewage sludge is digested in digester tanks. The digested sludge, which is dewatered by centrifuges, is co-incinerated in power stations and cement plants as well as partly in the sludge incineration plant of the Ruhleben sewage treatment plant.
