HUBER Solutions for Wastewater Heat Recovery from Sewers
Wastewater contains thermal energy, and we can recover some of this energy. Only seldom is wastewater warm enough to permit direct water or building heating. However, we can recover wastewater heat with heat pumps.
Heat pumps work like a refrigerator: they withdraw heat from a lower-temperature medium, thereby cooling it, and transfer the heat to a warmer medium, thereby warming it further. The lower the temperature difference between the two media, the higher is the energy efficiency ratio of the heat pump, which is the ratio of its heat yield, divided by its power consumption, and is in a range between 4 and 6 for low-temperature heat recovery from wastewater.
We offer various HUBER Solutions for wastewater heat recovery:
- Local and Short Heat Loops (decentralized heat recovery)
- Heat recovery from Sewage (HUBER Solution ThermWin® )
- Sludge Drying with Effluent Heat (at central wastewater treatment plants)
