The wastewater reaches the heatexchangers with approx. 45°C. There is no need to separate or filter waste-water before the heatexchanger, which reduces overall cost of the intallation.

In the heatexchanger the freshwater gets heated to an average of approx. 30°C.


Even if the total wastewateer of the facility is used, including water from toilets for example, the AWT-928 heatexchanger can deal with that no problem and still recover the heat from the wastewater.
