The reverse osmosis effect using the semi-permeable membrane existing in nature allows you to remove about 99% of mineral materials, ionized inorganic materials, various impurities, bacteria and germs, SS contained in the polluted underground water, rusts and iron in the faucet water and 2-D synthetic materials of some water supplies affected by industrial waste water (300 molecule weight or greater). It is used as a pre-process for the ultra pure water for semiconductors and it is used for a wide range of water treatment facilities including the sea water treatment facility.

This device manufactures pure water by passing the supplied water through the strong acid cation exchange resin and the strong alkaline anion exchange resin inside a single tower. If the supplied water contains a large amount of salt, it very effective in performing pre-processing with the strong acid cation exchange resin and the weak alkaline anion exchange resin. Compared to the two-bed ion exchange system, it can maintain more stable water quality depending on the quality of the supplied water and the change in fluid speed.

This device eliminates the cations by passing the supplied water through strong acid cation exchange resin and then eliminates the anions by passing it through strong alkaline anion exchange resin. In addition, the degasifier installed in the front area of the anion exchange tower removes CO2. In this way, the amount of anion is successfully reduced prior to entry to the anion exchange tower. Therefore, it is desirable to reduce the consumption of NaOH, regenerative agent by reducing the size of the anion exchange tower.
