    【性能及特点】

      EDI device is a continuous water purification process, so the product water quality stable, the resistivity is commonly 15 m Ω cm, up to 18 m Ω cm, can reach the indexes of the ultrapure water.Mixed bed ion exchange facilities of water purification process is intermittent, after has just been regeneration, water quality is higher, its products and until the next regeneration, its product water quality is poorer.

  • 1, small floor space, omitted and regeneration of the mixed bed equipment;
    2. Water continuous stable production, high water quality, and the mixed bed resin in water quality will become worse in the near failure;
    EDI device is a continuous water purification process, so the product water quality stable, the resistivity is commonly 15 m Ω cm, up to 18 m Ω cm, can reach the indexes of the ultrapure water.Mixed bed ion exchange facilities of water purification process is intermittent, after has just been regeneration, water quality is higher, its products and until the next regeneration, its product water quality is poorer.
    3. The operation cost is low, renewable power consumption only, without acid and alkali, save the material cost;
    EDI device running costs including power consumption, water consumption, drugs and equipment depreciation cost, eliminating the acid and alkali consumption, recycled water, sewage and waste water treatment cost.In terms of power consumption, EDI device is about 0.5 kWh/t water, mixed bed process about 0.35 kWh/t water, the cost of power consumption in power plants is more economic, can use the auxiliary power price calculation.In terms of water consumption, water production rate is high, EDI device use recycled water, so in terms of the operating cost is lower than the mixed bed.As for the agent fees and the equipment depreciation cost both.In general, in the operation cost, conventional tons of water running costs are higher than EDI device of the mixed bed.EDI device, therefore, the cost of the investment in a few years can be recycled completely.
    4. The remarkable environmental benefits, increase the safety of operation;
    EDI belong to environmental protection technology, do not need to acid, alkali chemical regeneration, save a lot of acid, alkali and water cleaning, greatly reduces the labor intensity.More important is no emissions, waste acid, waste alkali liquor belongs to the chemical formula of water treatment systems, it don't need to acid, alkali storage, handling, and no waste water discharge, so it has a special appeal to new users
