ABSTRACT:
A method for controlling the growth of bacteria and algae in utilitarian bodies of water such as industrial cooling towers, swimming pools and hot tubs is described. The method comprises adding to the water novel trivalent silver compounds. Said compounds are light stable and can be supplied as liquid concentrates which will not precipitate any silver whatsoever from saline waters nor will the concentrates stain skin or discolor surfaces. Said compounds meet the rigid EPA standards of killing 100% of select coliforms within ten minutes and are efficacious at concentrations as low as 1-2 PPM.
