Compact and powerful: EVALED RVF 25 wastewater evaporator with mechanical vapour recompression

THE CLIENT'S NEEDS

The customer's goal was to reduce its disposal costs for the waste water generated during production by 50 per cent. In addition, a solution was to be found to recover the sugar used in production. 

 

THE SOLUTION

Evaporators with mechanical vapour recompression were used. The EVALED®RV F plants used produce distillates that comply with the regional regulations for the direct discharge of wastewater. The concentrate is reused as animal feed.
