Abstract
Improvements introduced in the object of the main patent No. 297,435 issued on July 10, 1964 for "A method for the regeneration of mixed beds of ion exchange resins", in a process for the demineralization of water, using a mixed bed of resins ion exchangers, of the weak electrolyte type, in which the mixed resin bed is regenerated by elution with water or aqueous saline solutions, at a temperature higher than that used in the adsorption operation, and in which the weakly basic resin has a titration curve that is shifted to a more acidic position by raising the temperature, and the weakly acid resin has a titration curve, at the temperature of the adsorption operation, such that some part of it falls within the area defined by the titration curves of the weakly basic resin, at the temperatures of the adsorption and elution operations, respectively, characterized improvements They comprise adjusting the pH of the water in equilibrium with the resin bed, during adsorption, and choosing a ratio of acid resin to basic resin such that the overlap of the titration curves of the acid and the base is maximized.
