Hot water/steam evaporator with natural circulation and heat exchanger with scraped heating surfaces.
The RW series evaporators have a heating system based on hot water or steam and operate under vacuum at 5 kPa and around 40°C (104°F). The client usually supplies the necessary power and mains water for heating the feed and cooling the distillate.
The output streams are: a distillate that can be recycled as water and a solid or semi-solid concentrate with a TDS content > 90%.
The RW series evaporators are designed to work both continuously and per batch, by using a pump to discharge concentrate or by stopping the process and emptying boiling chamber.
The RW series production capacity varies from 3,000 to 12,000 liters per day. By using an optional intermediate heat exchanger, the RW series can operate using steam as the heat source. As in every EVALED™ product, evaporation process is controlled by a PLC, that controls the automatic feeding of wastewater to be treated and distillate and concentrate discharge, requiring only minimum supervision by the operator.
