Secondary Reverse Osmosis Equipment + EDI CDI
Introduction of CDI
CDI is an abbreviation of CEDI (Continuous electrodeionization), 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 15-18MΩ.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:
