The present invention relates to certain compositions and processes useful for inhibiting the growth of microorganisms in water and, in particular, water used for industrial purposes; for example, in the manufacture of paper, in cooling water systems in effluent water treatment, and in secondary recovery petroleum operations. The novel processes and compositions of the present invention are processes or mixtures which show unexpected synergistic activity against microorganisms, including bacteria, sulfate-reducing bacteria, fungi, and algae, which produce slime in aqueous systems where such slime is objectionable from either an operational or aesthetic point of view. Specifically, the invention is directed to the use of compositions comprising 2-(thio-cyanomethylthio)benzothiazole and 2'-hydroxyethyl 2,3-dibromopropionate or 2'-hydroxyethyl 2-bromoacrylate.
本发明涉及某些用于抑制水中微生物生长的组合物和工艺,特别是用于工业用水,例如制造纸张、废水处理中的冷却水系统和次生石油采收操作中的水。本发明的新型工艺和组合物是一种显示出意外协同作用的工艺或混合物,可对微生物,包括细菌、硫酸盐还原细菌、真菌和藻类产生粘液的水系统中的粘液产生出发挥作用,这种粘液在操作或美观方面都是不可取的。具体而言,本发明涉及使用包含2-(硫氰基甲硫基)苯并噻唑和2'-羟乙基2,3-二溴丙酸酯或2'-羟乙基2-溴丙烯酸酯的组合物的用途。
