Veolia says its EVALED PC series of heat pump vacuum evaporators reduces wastewater disposal costs and offers opportunities for recovering raw materials including APIs, disinfectants, proteins and glycols as well as recycling water. Offsite disposal of wastes containing APIs and similar ingredients is expensive, often involving incineration or complex chemical treatment. Veolia says evaporation using EVALED PC evaporators is a sustainable and environmentally friendly alternative that can reduce the waste volume by up to 90%. As EVALED PC evaporators operate under vacuum, water boils in the range of 30-40°C. The resulting low temperature evaporation means that it is possible to recover heat sensitive materials from wastes and, with a typical electrical consumption of only 0.15 kWh per litre of distillate, the carbon footprint is small.
