    • 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.
    • 一体式冷却水处理组合物包括高浓度的过氧化物,优选过氧化氢,与多元醇和膦酸盐组合以使浓缩溶液中的过氧化物稳定。 组合物还包括黄色金属腐蚀抑制剂,例如芳族三唑和任选的聚合物分散剂和黑色金属腐蚀抑制剂和/或钼酸盐金属腐蚀抑制剂。 在该组合物中,膦酸盐,优选HEDP,既用于稳定过氧化物,同时也为冷却塔提供抗垢处理。 由于HEDP提供的稳定性及其抗鳞屑性能,可以配制成一种高浓度稳定的一体化处理组合物,可以加入,以有效控制杀生物活性,防垢和腐蚀。
