    摘要: 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, thereby 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 existing 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 directly with the biofilm encased microorganisms. Upon the death of the organisms, the polysaccharide/protein 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 organics on the surface of the microfiltration membrane, thereby reducing the frequency and duration of the membrane cleaning and ultimate replacement.

    摘要: A method has been found for the removal of microbial biofilm on surfaces in contact with systems, including but not limited to aqueous systems, which comprises adding to the aqueous system an effective amount of a polyethyleneimine surfactant to substantially remove microbial biofilm, from surfaces in aquatic systems, while presenting minimal danger to non-target aquatic organisms at discharge due to their very low discharge concentrations.

    摘要: A packaging system for an acidic product and a method for adding the acid product to a water system, wherein the packaging system has a multi-layer packaging film with a water-soluble outer layer and an inner layer comprising a pH-sensitive polymer. The inner layer is stable at the pH of the acidic product and dissolves when exposed to a pH greater than dissolution pH of the inner layer, the dissolution pH being greater than the pH of the acidic product. In one example, the dissolution pH of the inner layer is between 5 to 8. When the pH of the water system reaches the dissolution pH, the product is released to the water system.
