　　How to solve the problem of cross-contamination of ion exchange resins?

　　Cross-contamination is a common phenomenon in the use of ion exchange resins. Once this happens, the leakage of sodium and chloride (sulfate) increases, and the leaching time increases continuously.

　　According to many ion exchange resin manufacturers, if such leakage is very troublesome, some large domestic manufacturers generally use recycling of effluent, but this method is very time-consuming. For these poisoned ion exchange resins in several different situations, we must do a good job in resuscitation treatment, we can see the importance of resuscitation for resins.

　　Using three-layer mixed bed resin, the greater advantage is to prevent cross-contamination of Yin-Yang resin, which can reduce the contamination of resin to a certain extent.

　　If the ion exchange resin bed is not hydrophobic to the above water level, it will lead to gravity change and stratification. It is suggested that the use of unconventional mixed bed resin can not only solve the problem of resin stratification, but also solve the problem of resin regeneration.

　　1. Dissolved iron ions can bind randomly to groups in various resins.

　　2. There are many iron ions in industrial hydrochloric acid for resuscitation, so the combination of resins with these iron ions will certainly occur, and then the poisoning of resins will occur.

　　3. If the equipment is corroded by hydrochloric acid caustic soda, the environment will be polluted if it is not well managed. Therefore, it is necessary to remove this substance in order to avoid affecting resin recovery in the equipment and increasing the difficulty of operation.
