Zero discharge effluent treatment plant
Decormetal is a company specialised in the surface treatment of aluminium. For a long time, their wastewater was treated in a conventional way with a physical-chemical purification installation. Recently Decormetal called on PCA to install a vacuum evaporator. Thanks to this evaporator, Decormetal can reuse all their wastewater and therefore no more wastewater is discharged.
Besides the evaporator, for the treatment of wastewater, an ion exchanger was placed to produce demineralised water. This ion exchanger operates in a closed circuit to produce demineralised water with maximum recovery.
