Description of ultra-pure water equipment
A, EDI device
EDI (Electrodeionization) is a revolutionary water treatment technology, which skillfully electrodialysis and ion exchange organic combination of membrane desalination process, is a high-tech green technology. EDI with continuous water purification equipment without acid regeneration and unattended, etc., has been gradually replaced by mixed bed in the preparation of the water system as a polishing device. This advanced technology, good environmental characteristics, easy to operate using more and more by people recognized, but also more and more widely popularized in medicine, electronics, electrical, chemical and other industries, has the international community has more than 3,000 sets of EDI device in operation, the total capacity has more than 30,000 M / H. Its appearance It is a revolutionary water treatment technology progress, marking the final round of industrial water treatment industry into the green industry.
Beijing Miao Feng Jie Water Technology Co., Ltd. EDI means is applied after the reverse osmosis system, replace the ion exchange resin with water quality and stability, low operating costs, easy operation and management, small footprint advantages.
Second, the nature of high-water equipment EDI ultra-pure water equipment, electronics industry ultra-pure water equipment, ultra-pure single crystal silicon device
Continuous electrodeionization (EDI, Electro deionization or CDI, continuous electrode ionization), is the use of mixed ion-exchange resin to water, ions, and these ions adsorbed again in the role of DC voltage, respectively, through the anion and cation exchange process film is removed. The process of ion exchange resins are continuously regenerated electricity, so no need to use acids and bases for the regeneration. This new technology can replace the traditional ion exchange unit to produce ultra high as 18M-CM Pure water and can more clearly be described as follows: EDI is the use of shade.
Cationic membranes, symmetrical form stacked in the middle of anion and cation membrane sandwiched anion and cation resin, respectively, in the role of DC voltage, be anion and cation exchange while under the influence of a voltage gradient produced by electrolysis of water occurs a large number of H + and OH-, the H + and OH- ion-exchange membrane in the middle of the anions and cations continue to carry out the regeneration stop due to exchange EDI - regeneration, so that water is increasing, so easy to produce high high purity water.
Third, the principle
1. Water entering the EDI system, flows into the main part of the resin / membrane inside, 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. Cation through cation membrane, discharged outside the resin / film.
5. anions through anion membrane, discharged outside the resin / film.
6. The concentration of the ions from the wastewater discharge flow path.
7. No-ionized water outflow from the resin / membrane.
Fourth, Beijing Miao Feng Jie Water Technology Co., Ltd. High-pure water equipment EDI performance advantages:
EDI ultra-pure water equipment, electronics industry ultra-pure water equipment, ultra-pure single crystal silicon device
1, continuous, stable production of high-quality water, no downtime due to resin regeneration;
2, no pollutant emissions, both environmentally friendly and eliminates the need for investment in waste water treatment;
3, compact structure, small footprint, saving space, but also has energy-saving advantages;
4, factory complete device debugging, a small on-site work, job training easy;
5, routine maintenance, simple operation, low labor intensity.
