Introduction to ultra pure water deionizer
ultra pure water deionizer is a device used to prepare ultrapure water. Whose main function is to remove ions and other impurities from water. The preparation of ultrapure water typically involves multiple steps and different techniques.The preparation process of ultrapure water generally includes steps such as pretreatment, reverse osmosis, ion exchange, and terminal treatment. In these processes, ion exchange is one of the key steps. Which uses ion exchange resin to remove positive and negative ions from water. Thereby achieving high purity.Specifically, ion exchange method utilizes ions fixed on resin to exchange with corresponding ions in water. Thereby removing minerals and other charged particles from the water. This method can effectively improve the electrical resistivity of water quality, usually reaching 18 M Ω* cm or higher.
