ABSTRACT:
An all-in-one cooling water treatment composition includes a high concentration of peroxide, preferably hydrogen peroxide, in combination with a polyhydric alcohol and a phosphonate to stabilize the peroxide in a concentrated solution. The composition further includes a yellow metal corrosion inhibitor such as aromatic triazole and optionally polymeric dispersants and ferrous metal corrosion inhibitors and/or molybdate metal corrosion inhibitors. In this composition the phosphonate, preferably HEDP, acts both to stabilize the peroxide and, at the same time, provides anti-scalant treatment for the cooling tower. Due to the stability provided by the HEDP and its anti-scalant properties, this can be formulated as an all-in-one treatment composition which is stable at high concentrations and can be added to effectively control biocidal activity, scale and corrosion.
