ABSTRACT:
The invention comprises a method for dispersing biofilms caused by the growth of slime-forming bacteria and other microorganisms in industrial process water. The method comprises adding an effective biofilm dispersing amount of a linear alkylbenzene sulfonate to the industrial process water which contains slime-forming bacteria and other microorganisms. In addition, an alternative embodiment of the invention comprises adding a compound selected from the group consisting of peracetic acid, glutaraldehyde, isothiazolone, methylene bisthiocyanate, thiocyanomethylthio benzothiazole, 2-bromo-2-nitro-1,3-propane diol, dibromonitrilopropane diol, tetralcishydroxy methyl phosphonium sulfate, decylthioethane amine, alkyl dimethyl benzyl ammonium chloride and combinations thereof.
