The GSA-CWS-WATER  process treats all kinds of metal wastewater by choosing solid catalyst fillers for different metals. They will separate and adsorb according to various metal ions in the WATER. When a certain concentration is reached, the equipment will be saturated and recycled. The regenerated concentrate of the metal is discharged into various numbered concentrators. Usually the concentration of the metal can reach 15-35 g/l. The concentration of the metal can be further processed to the required concentration of the factory or 99.9% high purity metal through GSA efficient electrolysis or low temperature evaporation. This technology is a new type of metal recycling and water recycling treatment process, which has the advantages of high recovery rate, high energy saving and discharge reduction and easy operation.
