In the past, the chlorine and hypochlorite are used as bleaching agent for wood and paper pulp bleaching in paper industry; nevertheless, the toxic effects restrict the speed of its promotion. Alkaline hydrogen peroxide and chlorine dioxide are considered as appropriate substitution. According to the requirements of wood process and paper industry, the article describes a new combined generator of alkaline hydrogen peroxide solution and chlorine dioxide which is developed for generating the alkaline hydrogen peroxide solution on the cathode and chlorine dioxide on the anode by the electrolysis of sodium chloride. The calculated composite cost of hydrogen peroxide and chlorine dioxide is 43% lower than that of traditional elemental chlorine-free and totally chlorine-free bleaching methods used on-site, on the same chemical equivalent.
