Wastewater contains thermal energy, and we can recover some of this energy with Heatpumps.
Using the HUBER ThermWin® system for heat recovery from sewage we withdraw sewage from the sewer low, screen it, pump it through above-ground Heat Exchangers, and then return it back into the sewer.
Because we screen and pump the sewage, we can use compact and cost-effective heat exchangers, wherein we generate a well-defined and turbulent flow for efficient heat transfer.
For screening we deploy the vertical screw screen ROTAMAT® Pumping Stations Screen RoK 4 that is compact and lifts the screening through its vertical auger. Returned sewage flushes the lifted screenings over a chute back into the sewer.
