Detailed Product Description

    The constant Electro-deionization (EDI) refers to the course of utilizing mixed ion exchange resin to absorb the anion and cation in water and these ions are get rid of by the exchange membrane of anion and cation in the condition of DC voltage. The ion exchange resin has no need to be regenerated by acid and alkali in the course. The new technology can produce ultrapure water with electric resistance of 18MΩ.cm instead of traditional DI plant.

    Ultrapure water often applies to micro-electrics, semi-conductor, electricity generation, preparation and extracting industries and laboratory. EDI ultrapure water can also be used as distilled water for pharmacy, water for crafts in chemical factories and other ultrapure water application fields.

     EDI utilizes the sufficient fixed gene and dissociative ions in out-phase ion exchange membrane that has certain selective penetrability and electrical conductivity, chemical and erosion resistance for ion in solution. Moreover, it has unique high compactness and low water permeability and therefore it is another water treatment technological membrane with revolutionary significance.

    Exchange theory: the positive membrane has strong acid active gene R-SO3- to form negative electric field and is easy for the ion with positive charge to absorb and pass; while the negative membrane has strong alkali active gene R-N+(CH3)3 to form positive electric field and is easy for the ion with negative charge to absorb and pass.
