PT Cipta Kawan Teknik Abadi alsois a provider of deionization solutions. Our water deionizers are rugged, pre-engineered,pre-assembled, standardized units that minimize expensive installation and start-up costs. We have designed our Deionization systems to maximize the efficiency and repeatability of the unit during the service and regeneration modes.
Electrodeionization (EDI) is process that uses ion exchange resin that absorb ions from dilute Water stream and then transports the absorbed ions through ion-exchange membranes into concentrate water stream under the influence of an applied electro field. In the process, ion-exchange resins do not need regeneration via acid or alkali. This technology could replace traditional Electrode Ionization (DI) equipment, product ultrapure water whose resistance up to 1.8 MΩ cm.
Advantage of EDI Technology
A mixed bed ion-exchange unit has to be regenerated by using acid and alkali, but an EDI system does not need such a process. This is a fundamental advantage of EDI technology over the conventional ion-exchange technology.
However, this advantage can be expressed in to other aspect as listed bellow:
1. EDI process does not consume regeneration chemicals.
2. EDI process does not create waste water and much more environmental
3. EDI systems do not require shutdown to regeneration
4. EDI systems are smaller than mixed bed ion exchange units
5. EDI process provides water of consistent quality
6. Operating expenses are lower than ion exchange units.
Application of EDI Technology
EDI typically may be used in any applications that require ultrapure water at a resistivity above 1 MΩ cm. The typical industries that use ultrapure water include:
1. Microelectronic and semiconductor product
2. Pharmaceutical and Biomedical industries
3. Chemical production
4. High pressure boiler such as the ones in power plants
