The review of data of the literature concerning the combined application of chlorine with ultraviolet irradiation (UVI) or ozone is presented. The analysis has shown, that efficiency of such combination in essential degree depends on a number of conditions which can be divided on two groups: the first – an optimality combination of certain doses for UVI and chlorine; the second – difference of influence of рН and temperatures for ozone and chlorine on efficiency of their combination with UVI.

Key words: water, purification, disinfection, chlorine, UVI, ozone, combination.
