Corey for you to answer:
EDI ultrapure water equipment is also known as continuous electrodesalination technology, is the use of mixed ion exchange resin adsorption of anions and cations in the water, at the same time these adsorbed ions in the role of direct current voltage, respectively, through the anion and cation exchange membrane and be removed from the process.EDI ultrapure water equipment in the process of ion exchange resins are electrically regenerated, so there is no need to use acid and alkali to regenerate. Therefore, there is no need to use acid and alkali regeneration. This new technology can replace the traditional ion exchange equipment to produce up to 18 megohm ultrapure water. Baiyuan water treatment editor for you to clearly describe the following: EDI is the use of anion and cation membranes, the use of symmetrical stacked form, in the middle of the anion and cation membranes sandwiched between the anion and cation resins, respectively, under the action of DC voltage, anion and cation exchange. And at the same time under the action of the voltage gradient, the water will be electrolyzed to produce a large number of H + and OH -, these H + and OH - on the ionic membrane in the middle of the anion, cation constantly regenerated. Due to the EDI non-stop exchange - regeneration, so that the degree of pure water is getting higher and higher, so it is easy to produce a high purity of high purity water.
