Complete vacuum evaporator treatment system solution for permanent wastewater treatment, environmentally friendly discharge, and reuse of water. For an optimal result, requirement-specific pre-treatment processes are used depending on the process water characteristics. The use of a vacuum evaporator allows the water to be returned to the production process and minimizes the costs. For further treatment and good distillate quality, additional processes can be applied depending on the application. Valuable by-products can be recovered from wastewater and reused.
