Improved regeneration method of ion exchange resin is described. Cation exchanger and anion exchanger(1) is seperated and regenerated with HCl and NaOH, resp. By washing these exchangers with cleaning water at the same time, the residual Na+ ion and Cl- ion is eluted to circulating water, and then both these ions is adsorbed in cation and anion exchanger, resp.
