Deionized Water System made in China DI water for rinse zones聽 In almost any pretreatment process, the last rinse before drying and coating is done with demineralized or deionized water, typically described as DI water. In some processes, several rinse zones are supplied with DI water, and some chemical suppliers even recommend filling the conversion bath with DI water.聽 The purpose of the last rinse is to remove any residual chemicals, avoid any salt deposits and to provide a clean surface for coating. A continuous supply of DI water ensures that the water quality is properly maintained.聽 Consequently, the water treatment solution is directly related to the quality of the pretreatment process. With our many years of experience as a supplier of water treatment units to the surface treatment industry we know how to design the optimum solution Electroplating Industry DI Water System by Reverse Osmosis Reverse osmosis is a membrane technology, which in water treatment is used for deionization, meaning for removal of ions or minerals from water. For deionization, water at high pressure side pass through a RO membrane, so the membrane can be divided in two sides: a concentrate side and a permeate side. The pressure differential between the concentrate side and the permeate side results in water flowing from the concentrate side and through the RO membrane into the permeate side, while nearly all ions or minerals remain on the concentrate side.
