Ions which are found in water in dissolved state are cationic (positive) and anionic (negative) charged ions. Removal of cationic and anionic ions in water through ion exchange method using resin is named as deionization and systems used for this purpose are called deionization systems.
Resin quantities in the tanks in DE Series Deionization Systems, are determined with the calculations made according to the raw water conductivity, flow rate of the passing water and ion retention capacity of the resin that is used. The system is fully automatic and controlled by valves with microprocessors. With the conductivity meter installed at the output, conductivity of water can be controlled and when output water conductivity exceeds the desired value the system enters washing process (regeneration) automatically.
