What is Thermal Evaporation?

Thermal evaporation treatment of wastewater is an efficient technique for the separation of water from waste. It is one of the simplest of the physical vapor deposition (PVD) techniques. Wastewater is heated until it is vaporised. The water vapour is condensed and collected as distilled water, leaving the solid waste behind.

Industrial Wastewater Evaporators

Evaled vacuum evaporators from Veolia Water Technologies are widely used for industrial wastewater treatment and process water treatment. They are low energy consumption systems that effectively treat industrial wastewater, providing excellent levels of separation while decreasing the disposal volume. These thermal evaporation systems are also used in manufacturing processes where there is a need to remove water from the product.

Wastewater Evaporation Benefits

Thermal wastewater evaporation provides a number of notable benefits:

  • The ability to effectively treat hazardous and difficult wastewater streams
  • A high percentage of water removal in production processes reducing disposal costs
  • High-quality distillate enables water reuse - Low power consumption and operating costs
  • Flexible system design and easy maintenance.
