Evapo-concentration

Evaporation

Objective and operating principle

Vacuum evaporation allows the recovery of the electrolytes transferred into the rinse baths.
Treatment baths are maintained at a constant concentration. The rinse flow rate is supplied by condensed water.
The thermodynamic unit design depends on the available thermal fluid and the flow rate to be evaporated.

Advantages

  • Complete recycling of condensed water
  • Elimination or reduction of effluent treatment
  • No waste production
  • Fully automatic and continuous operation
