The growth of biofilm present in open recirculating water systems is inhibited by introducing into the water comprising such a water system (a) a source of free halogen, e.g. e chlorine and (b) a source of di(lower alkyl) substituted-2-oxazolidinone, the mole ratio of (a) to (b) and the combined amount of (a) and (b) being sufficient to at least inhibit the growth of the biofilm, e.g., the bacteria comprising the biofilm, the source of free available halogen being present in less than biostatic amounts.
在开放循环
水系统中
生物膜的生长被抑制,方法是向组成该
水系统的
水中引入(a)自由卤素的来源,例如
氯和(b)二(较低烷基)取代-
2-噁唑烷酮的来源,其中(a)与(b)的摩尔比和(a)和(b)的综合量足以至少抑制
生物膜的生长,例如,包括
生物膜的细菌,自由可用卤素的来源以低于
生物静态的量存在。
