Standard electric de-ionizing system, "CODES"
"CODES" is the demineralizer to meet the future needs and requirements. It realizes continuous operation of both service run and regeneration which does not require the regeneration chemicals.

< Advantages >

Only a water and electricity is required
No need of the waste water treatment
No need of the chemical storage tanks
No need of the product water reservoir
Save the space ( one fourth of the conventional type )
Easy management due to automatic operation


< Application >

For ultrapure water production for semi conductor industry
For pharmaceuticals and food industry
For laboratory and hospital use
For the alternative use to cartridge type demineralizer


< System description of "CODES" >

It consists of activated carbon filter, pre filter, reverse osmosis membrane, carbon dioxide removal membrane and "CDS" stack where electric deionization is carried out.
In case of city water, the free chlorine is removed by the activated carbon filter, then most of ions are removed by reverse osmosis membrane and the dissolved carbon dioxide is removed by liquid/vapor separation membrane, finally residual ions are removed by "CDS" stack.
"CDS" stack consists of cation/anion exchange membranes, ion exchange fiber and direct current power generator.
The ion exchange membranes form de-ionization chamber where ion exchange fiber is filled and concentration chamber.
The water to be treated enters into de-ionization chamber and the ions in the water are drawn to the concentration chamber by the electrical force, cations to the cathode(-) through cation exchange membrane and anions to the anode(+) through anion membrane. The ion exchange fiber works to transport the ions easily and completely.

< Ion exchange fiber >

The ion exchange material is necessary to assist the transportation of the ions to concentration chamber.
It is better to have the shortest route consisting of the same polarity for rapid transportation of ions in de-ionization chamber. Our system using the fiber provides such route easily, whereas the conventional system using ion exchange resin which does not always form the shortest route.
