Commercial Water Treatment System Ultra Pure Lab Water System Body EDI System

EDI ultrapure water equipment ultrapure water manufacturing historical process first stage: pretreatment filter --> positive bed --> negative bed --> mixed bed second stage: pretreatment filter --> reverse osmosis --> The current stage of the mixed bed: pretreatment filter --> reverse osmosis --> EDI (no acid or alkali required) In recent decades, the mixed bed ion exchange technology (D) has been the standard process for the preparation of ultrapure water. Because it needs periodic regeneration and consumes a large amount of chemicals (acid and alkali) and industrial pure water during the regeneration process, and causes certain environmental problems, it is necessary to develop an acid and alkali-free ultrapure water system. Because traditional ion exchange has become increasingly unable to meet the needs of modern industry and environmental protection, the EDI technology that combines membrane, resin and electrochemical principles has become a revolution in water treatment technology. The regeneration of the ion exchange resin uses electric energy instead of acid and alkali, so it is more satisfied with the environmental protection requirements of today's world.

EDI (Electrodeionization) is also known as continuous electro-deionization technology. It scientifically integrates electrodialysis technology and ion exchange technology. Through the selective permeability of cation and anion membranes to cations and anions, and ion exchange resins exchange ions in water It can realize the directional migration of ions in the water under the action of the electric field, so as to achieve the deep purification and desalination of water, and the hydrogen ions and hydroxide ions generated by water electrolysis can continuously regenerate the filling resin, so the EDI water production process does not The regeneration of acid and alkali chemicals can continuously produce high-quality ultra-pure water. It has the advantages of advanced technology, compact structure, and easy operation. It can be widely used in electric power, electronics, medicine, chemical, food and laboratory fields. The green revolution in processing technology. The effluent water quality has the best stability.
