ABSTRACT:
A method of 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 includes adding to the water trivalent copper compounds including the periodate and chelate complexes of biuret an tris-(hydroxymethyl) aminomethane. These compounds meet EPA standards of killing 100% of select coliforms within 10 minutes and are efficacious at concentrations as low as 5-9 PPM.
