A process has been found which increases the efficiency and effectiveness of introducing antimicrobial compounds into complex biofilm matrices through the use of liposome carriers, therein removing the biofouling in industrial water bearing systems, including piping, heat exchanges, condensers, filtration systems and fluid storage tanks. According to one embodiment of the invention, antimicrobial compound containing liposomes are added to water systems prone to biofouling and biofilm formation. The liposomes, being similar in composition to microbial membranes or cells, are readily incorporated into the exiting biofilm. Once the antimicrobial compound containing liposomes become entrained with the biofilm matrix, the decomposition or programmed disintegration of the liposome proceeds Thereafter the biocidal aqueous core is released to react directh with the biofilm encased microorganisms. Upon the death of the organisms, the polysaccharide/prolem matrix decomposes and thereby results in reduced fouling of the water bearing system, resulting in increased heat transfer, increased flux, less deposit of colloidal and particulate solids and dissolved orgamcs on the surface of the microfillration membrane. thereby reducing the frequenev and duration of the membrane cleaning and ultimate replacement.
