GSA CWS - WATER WATER treatment process and chemical clean WATER without precipitation method, is based on different metal, choose different solid catalyst for packing, direct metal adsorption and enrichment of WATER treatment, proper around 90% of the circulating WATER, for equipment operation of saturated, put the adsorption to the metal in the regeneration way with 4% to 7% sulfuric acid washed out and washed out the metal concentration can reach 15-35 grams/liter, discharge of metal thick liquid can recycle to the production line or by GSA further efficient cyclone electric product processing, get 99% pure copper, nickel, gold, silver and other heavy metals, The recycling resources are recycled and the waste water discharged by the factory after the waste water is purified by gsa-phcs is ensured to reach the standard.
