ABSTRACT:
We have determined that simultaneous use in industrial waters of certain water soluble polymers in the presence of ozone is acceptable for scale control, corrosion control, microbiological control and the like. The preferred polymers used with ozone and those polymers that are homopolymers and copolymers containing at least 50 mole percent of acrylic acid or methacrylic acid, mixtures thereof. Certain other monomers may be used with the acrylic acid and methacrylic acid monomers, and still function as scale inhibitors and corrosion inhibitors in the presence of ozone in industrial waters. The industrial waters are particularly recirculating cooling waters.
