Application of EDI in electroplating coatingedit

In the electroplating and coating industry, in order to increase the surface finish, brightness, and adhesion of the plated parts, the preparation of the electroplating solution requires pure water with a conductivity of 15uS/cm or less, and a conductivity of 10uS/cm when rinsing the plated parts The following pure water is used for cleaning. The electroplating industry water treatment system includes the pure water treatment system required for the preparation of the electroplating solution before electroplating, and the rare metal recovery and rinsing water recycling wastewater zero discharge system in the electroplating rinsing wastewater. Usually the system is composed of ultrafiltration device, reverse osmosis device, ion exchange device, EDI device, etc. to meet the water quality requirements of the electroplating industry.
