  Improved biocidal composition and method for controlling biofouling and microorganism population levels in recirculating water systems such as cooling towers, swimming pools or spas is disclosed and claimed. The composition comprises a hypochlorite donor and a bromide ion donor in proportions selected to maintain a mole ratio of the sum of all bromine containing species to the sum of all hypohalite species in the recirculating water of about 0.2 to about 20. The method comprises introducing into the recirculating water a mixture or combination of a hypochlorite donor and a bromide ion donor in an amount sufficient to maintain a ratio of the sum of all bromine containing species to the sum of all species in the recirculating water in the range of about 0.2 to about 20. In addition, a bromine volatilization suppressant may be introduced into the recirculating water to inhibit loss of bromide ion through volatilization of bromine containing species formed by reaction of the hypochlorite donor and the bromide ion donor. One or more scale inhibitors and compacting aids may also be added.

  本发明公开了用于控制冷却塔、游泳池或水疗池等循环水系统中生物污垢和微生物数量的改进型杀菌组合物和方法。该组合物由次氯酸盐供体和溴离子供体组成，其比例可选，以保持循环水中所有含溴物种之和与所有次氯酸盐物种之和的摩尔比约为 0.2 至约 20。该方法包括向循环水中引入次氯酸盐供体和溴离子供体的混合物或组合，其用量足以维持循环水中所有含溴物种之和与所有物种之和的比率在约 0.2 至约 20 的范围内。此外，还可在循环水中加入溴挥发抑制剂，以抑制次氯酸盐供体和溴离子供体反应形成的含溴物种挥发而造成的溴离子损失。还可添加一种或多种阻垢剂和密实助剂。
