A biodelivery system has been found which increases the efficiency and effectiveness of introducing anti microbial compounds into complex biofilm matrices through the use of liposome carriers, thereby removing the biofouling in industrial water bearing s\ stems, including piping, heat exchanges, condensers, filtration s> stems 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 existing biofilm Once the antimicrobial compound containing liposomes become entrained with the biofilm matrix, the decomposition or disintegration of the liposome proceeds Thereafter the biocidal core is released to react directly with the biofilm encased microorganisms. Upon the death of the organisms, the matrix decomposes and thereby results m reduced fouling of the water bearing system, resulting in increased heat transfer, increased flux, less deposit of colloidal and particulate solids and dissolved organics on the surface of the microfiltration membrane, thereby reducing the frequency and duration of the membrane cleaning and ultimate replacementLa présente invention concerne un système de distribution biologique qui augmente lefficacité et le rendement de lintroduction de composés anti-microbiens dans des matrices de biofilm complexes par lutilisation de vecteurs liposomiaux, ce qui permet déliminer la contamination biologique des réseaux deaux industriels, y compris dans les canalisations, les échangeurs de chaleur, les condenseurs, les systèmes de filtration et les réservoirs de stockage de fluide. Selon lun des modes dapplication de linvention, les liposomes contenant le composé antimicrobien sont ajoutés aux réseaux deau sujets à contamination biologique et formation de biofilms. Les liposomes, de composition similaire aux membranes microbien
