Abstract

A method of elimination and prevention of the accumulation of biological slime on the surfaces of commercial and industrial refrigerant systems and the like, which consists of treating the water used in the operation of these cooling towers with at least 0.5 ppm of a copolymer of propylene oxide/ethylene oxide, the polymer of which comprises a polyoxypropylene glycol polymer with a molecular weight of 1500-2000 which has reacted with 5 to 30% by weight of ethylene oxide.
