Study on swirl bed electrochemical ion exchange and in-situ regeneration technology

ABSTRACT

In this paper, the electrochemical ion exchange technology was adopted, and the self-made swirl bed electrochemical ion exchange device was taken as the research object. The results presented that the device had the best water treatment effect with 1:0 of the split ratio and the smaller effluent flow. When the electrochemical device was filled with the mixed ion exchange resin after in-situ regeneration, after 5 h of operation, the hardness removal rates of cathode and anode were 6.25 and 22.5%, respectively. Backwash experiment revealed the treatment effect of power backwash was better than that of large flow backwash.
