Detailed Product Description: | Water treatment technology? A, EDI Technical Overview ??? EDI (Electrodeionization) is a revolutionary, it skillfully electrodialysis and ion exchange organic combination of membrane desalination process, is a high-tech green technology. EDI with continuous water purification equipment, no acid regeneration and unattended, etc., have been gradually replaced by a mixed bed polishing equipment used in the preparation of the water system. This environmental characteristics of advanced technology, simple operation uses, more and more recognized by people, but also more and more widely popularized in medicine, electronics, electrical, chemical and other industries, the international community has been 3,000 multiple sets of EDI device operation, the total capacity has more than 30,000 M / H. Its appearance is a revolutionary water treatment technology progress, marking the final round of industrial water treatment industry into the green industry. ? Second, the history of the development of high-purity water treatment technology first stage: pre -> sun bed -> anion bed -> mixed bed of the second stage:?? Pretreatment -> Reverse Osmosis -> Mixed bed? Third stage: pre -> RO -> EDI device ??? reverse osmosis (RO) membrane separation technology is a use of the method of removing the water ions, although the reverse osmosis system water at 95% to 98%? ion removal, but still can not meet the requirements of industrial production, and its subsequent processing must use ion exchange equipment. ? ??? Recent decades, mixed bed ion exchange technology has been used as a standard process for the preparation of pure water. Because of its need for periodic regeneration and regeneration process using a large number of chemicals (acid) and water, and therefore have been difficult to meet in acid-free water system. ? ??? Because the traditional ion exchange has become increasingly unable to meet the needs of modern industry and environmental protection, so the membrane and resin bond EDI technology has become a revolution in water treatment technology. Regeneration of ion exchange resins using electricity, and no longer need to acid, and therefore more satisfied with the environmental requirements of today's world. ? ??? Since 1986 EDI technology industrialization, the world has nearly 2,000 sets of EDI system was installed, has been particularly strong growth in the pharmaceutical, semiconductor, power and surface washing and other industries, while the waste water treatment, beverage and microbial and other areas have also been widely used. ? EDI device is applied after the reverse osmosis system, replace the ion exchange resin, with quality and stability, low operating cost, easy operation and management, small footprint advantages. ? Three, E-CellTM features? ??? E-CellTM EDI technology is a revolution. It is a subsidiary of General Electric Company E-Cell, Canada and Japan Asahi Glass Company jointly developed and put on the market in 1996. This patented technology to fully meet the non-acid, low cost, the market needs to replace the primary mixed bed. ? ??? EDI is a revolutionary water treatment technology progress. The regeneration of ion exchange technology electric desalting technology to replace traditional mixed ion exchange demineralization process DI. Achieve high desalination effect by selective ion exchange resins and ion-exchange membrane, joint technology and reverse osmosis water production combined make up 10 ~ 15MΩ? CM high specification water production. ? Fourth, the working principle of? 1. Water entering the EDI system, flows into the main part of the resin / membrane interior, while the other part flows along the outside of the template, in order to wash away the outside of the plasma membrane revealed. 2. Resin trapped ions dissolved in water. ? 3. Trapped ions in the electrode, the anions to the positive direction of movement, cations to the negative direction. ? 4. Cations through the cation membrane, discharged outside the resin / film. ? 5. Anions through anion membrane, discharged outside the resin / film. ? 6. Concentrated ions from the wastewater discharge flow path. ? 7. Deionized water outflow from the resin / film. |
