In the exchange layer of ultra-pure ion purifier, the dielectric ions in the water undergo directional movement under the action of a DC electric field, and the water is purified by the selective permeation of exchange membrane. Not only can the unqualified UP water prepared by reverse osmosis (RO water) and water purification machine (the ion content exceeds the standard) be further purified to meet the requirements of ion chromatography , but also the UP Water prepared by the water purification machine can be further purified to meet the detection requirements of ultra-trace ions in the semiconductor, nuclear power, and thermal power fields.
