EDI ultrapure water System Working Principle: 1. water enters EDI system, major portion flows into resin/film inside, and another part is along template flows outside, to wash away the ion appearing outside film.2. the molten ion of depositing in resin trap water.3. the ion being trapped is under electrode effect, and negatively charged ion is to positive extreme direction campaign, and positively charged ion moves to negative pole direction.4. positively charged ion sees through cationic membrane, discharges outside resin/film.5. negatively charged ion sees through anionic membrane, discharges resin outside film.6. the ion having concentrated is discharged from waste water stream.7. deionized water flows out in resin/film.
EDI ultrapure water system is generally to adopt ion-exchange method, and its technical process is: former water → former water force (forcing) pump → more medium filter → activated charcoal filter → water softener → accurate filter → positive resin filtering device → negative resin filtration unit → yin and yang resin mixed bed → millipore filter → use water spot.
The activated carbon adsorption strainer of EDI ultrapure water system, its cylinder body adopts the design of hydraulic simulation major diameter, and adopts particle diameter reasonable, and specific surface area is greater than 1000m
2the highly effective active carbon of/g, its existing special efficacy is filtered again the functions such as efficient adsorption, greatly carries the work-ing life of high yield water degree of purification and carbon.But existing activated carbon adsorption filter replacement gac is time-consuming, effort, causes and uses inconvenience.
