Ultra-pure water equipment is a water treatment system that utilizes reverse osmosis and electro-deionization technology to produce ultra-pure water.

Under the influence of a direct current electric field, cations and anions in the ion exchange resin of the freshwater chamber migrate towards the negative and positive electrodes, respectively, through the channels formed by the resin and the membrane. Cations pass through the cation exchange membrane, while anions pass through the anion exchange membrane, entering the concentrated water chamber to form concentrated water.

·Simultaneously, the cations and anions in the EDI water exchange with the hydrogen ions and hydroxide ions in the ion exchange resin, forming ultra-pure water (high-purity water). The super-limited current continuously regenerates the ion exchange resin with a large amount of hydrogen ions and hydroxide ions produced by the electrolysis of water.

·Primarily used for optical lens cleaning.
