DEIONIZATION (DEMINERALISATION) OF WATER

The devices are designed for demineralization of raw water using the ion exchange resins.
As a result of the flow of contaminated water through the above-mentioned device follows the water deionization occurs and the result is demineralized water. During the process of deionization (inside the ion exchangers) the cationic impurities is retained on the cation exchange resin remaining in the hydrogen form, and anionic impurities are retained on the anion exchange resin remaining in the hydroxyl form. When the cationit resin is exhausted is regenerated with an acid solution, causing re-transition of the absorbed ions (salt cations in the water) to a solution (the eluate). The anion exchange resin after exhaustion is regenerated with sodium hydroxide solution, resulting in the re-transition of the ions (anions of salt) to a solution (the eluate). The above-mentioned eluates of both ion exchange columns are directed to a specially designed container.

STRUCTURE:
The above-mentioned device consists of two ion-exchange columns placed in the rack: cation and anion exchangers, respectively filled with ion exchange resins (cation and anion exchange resin). Each ion-exchange column has input and output entries in the top marked as IN and OUT and the venting valve.
In addition, the device includes: an operational valve system, connection hoses, diaphragm pump type TPS-1 Tapflo, air pressure regulator, pre-filter (20 micron), conductivity meter, the solenoid valve.
