A process for disinfecting a water supply, employing as disinfectant a combination of monochloroamine and hydrogen peroxide for use as a disinfectant. The concentration of monochloroamine is preferably at least 0.02 ppm and generally not more than 0.5 ppm. The concentration of hydrogen peroxide is preferably at least 0.1 ppm and often not more than 1 ppm. Preferably the weight ratio of hydrogen peroxide to monochloroamine is in the range of 4:1 to 20:1. An advantage of employing a combination of monochloroamine and hydrogen peroxide as disinfectant is that a comparatively long lasting residual bactericide is thereby provided.
