Abstract:
A method for inhibiting the microbial colonization of surfaces in contact with an aqueous system which comprises adding to said system from about 1 to 150 ppm of a combination of (a) alkylsulfosuccinate surfactant with alkyl chain lengths of from about 5 to 13 carbons and (b) polyoxyethylene-polyoxypropylene block copolymer surfactant to substantially prevent adhesion of microbes to said surfaces while preserving the viability of microbes in said system, allowing for discharge of the microbes from said system, said polyoxyethylene-polyoxypropylene block copolymer surfactant exhibiting no colonization inhibition or substantially no colonization inhibition at concentrations less than 100 mg/l when used alone.
