Technical Field

[0001] The utility model belongs to the technical field of electroplating supporting equipment, and in particular relates to pure water preparation and filtering equipment for electroplating. Background Art

[0002] The electroplating process is a method of plating a conductor with a layer of metal using the principle of electrolysis. Electroplating refers to a surface processing method in which the base metal to be plated is used as the cathode in a salt solution containing the pre-plated metal, and the cations of the pre-plated metal in the plating solution are deposited on the surface of the base metal through electrolysis to form a coating. The coating performance is different from that of the base metal and has new characteristics. The water treatment system for the electroplating process includes a pure water system for preparing the plating solution before electroplating, a zero-emission system for recovering rare metals in the electroplating rinse wastewater, and a water purifier for recycling the rinsing water for electroplating wastewater treatment. A pure water machine is used in the pure water system.
