Product Description

Introduction of CDI

CDI is an abbreviation of CEDI (Continuouselectrodeionization), which is a novel super-purified water preparing technology.After the CDI device is arranged in the reverse osmosis system and the deep desalting is carried out, the super-purified water of ****8M&branded;.cm can be prepared.

Principle of CDI

CDI device is characterized in that the ion exchanging resin is filled between anion exchanging membrane and cation exchanging membrane so as to form a CDI unit, the highly purified water is prepared by the resin, the ions H+ and OH generated by water electrolysis are utilized so as to re-generate failed resins in membrane stacks.

CDI hot-water sterilizing module

The CDI instantaneous temperature increasing/decreasing sterilizing module is generally used after the reverse osmosis system and can remove the carbon dioxide, remaining salt, silicon dioxide, boron, organic carbon and other ions of slight quantity in reverse osmosis water. The CDI instantaneous temperature increasing/decreasing sterilizing module can be widely applied to the industries such as biotechnology, pharmacy and other industries which must comply with the USP, EP and JP. In the above industries, the hot water is needed for quick disinfection, and the chemical agent is not used. The CDI instantaneous temperature increasing/decreasing sterilizing module has the following excellent performances:

◆Hot water disinfection is carried out under the temperature of *5℃.

◆The temperature does not need to be increased or decreased slowly.

◆The disinfection pressure is improved to 2.0bar/*0psi.

◆Dual O-shaped sealing rings are used for sealing, thus ensuring no leakage occurs during the running process of the membrane stack.

◆The module can run continuously under the conditions of 7bar and *5℃.

◆The manufacturing material complies with the requirements of Food and Drug Administration(FDA).

CDI EDI

* In water used for injection and complying with the USP*4 standard, the RO-EDI-RO technology is used so that the second stage of RO (reverse osmosis) system is installed after the EDI to be used as the final membrane separation application.
