A method of disinfecting water wherein electrodes of a copper-silver alloy which are immersed in the water and the polarity of which is changed at certain intervals are connected to a direct current source for the production of copper and silver ions. Sodium persulfate is added to the water for oxidation of organic substances. Said method is especially useful for disinfecting swimming pool water resulting in an easily controllable and effective disinfection of the water without any damage to the human body.
