Utilisation of wastewater heat in the sewage canal, sewer,

Gold under our feet

Description

The wastewater in the sewers is an ideal source of energy when combined with heat pumps and cooling machines, for heating and cooling of buildings. Per our experience, the minimal requirements for such a plant include: a wastewater flow of approx.. 10 l/s a wastewater temperature level of about 10°C a power requirement from 100kW (for heating and cooling from ca. 50kW). During the course of conveying wastewater to the sewage treatment plant, there are many possibilities for exploiting thermal energy. Wastewater can also be used many times over consecutively as energy source. Despite new inflows, or the confluence into larger canals, but also through heat influx from cooling systems, the change in temperature of the wastewater is mostly marginal. Innovative cities have ready energy guidelines (energy plans), based on which you can orient yourself to find out whether there is a suitable wastewater canal in your near vicinity (maximally approx. at a distance of 200 m).
