ABSTRACT:
A pair of electrodes formed of silver-copper alloy depend from the bottom wall of a floating container. The latter is arranged to float on the surface of a body of water to be treated and contains a battery which is connected in circuit with the electrodes through a timer switch and a current reversing switch. Passage of a direct current across the electrodes ionizes the water and the silver and copper ions destroy and prevent the growth of bacteria and algae.
