Evaporation Objective and operating principle The 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 on 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
