  • Slime control compositions and methods of using the same
    Patent number: 4293559
    Abstract: 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.
