  • Publication number: 20250066695
    Abstract: The present disclosure provides methods for cleaning industrial equipment. In one example, a method for reducing microorganism from industrial equipment includes: (1) cleaning the equipment with one or more CIP compositions using a CIP process; (2) rinsing the equipment with water; (3) adding an enzyme composition into the CIP process; (4) analyzing a sample of the fluid within the CIP process before, after, or before and after the addition of the enzyme composition to detect microorganisms; and (5) modifying the CIP process in response to any detected microorganism.

  • Publication number: 20150079158
    Abstract: An improved stabilized biocidal delivery system has been found which increases the efficiency and effectiveness of introducing antimicrobial compounds into complex bio-film matrices through the use of liposome emulsion in an ethoxylated compound, thereby removing the bio-fouling in industrial water bearing systems, including piping, heat exchangers, condensers, filtration systems and fluid storage tanks. The liposome emulsion is comprised of a vesicle encapsulated biocide that is stabilized against chemical and heat degradation over longer periods of time than previously possible through the incorporation of one or more stabilizer compounds.

  • Patent number: 8784659
    Abstract: 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.

  • Publication number: 20140046629
    Abstract: The present invention concerns an apparatus for deposition monitoring in a water system comprising a deposition measurement system, a DC power supply connected to a conductive deposition monitoring surface and a counter electrode, the apparatus has a first treatment configuration and a second treatment configuration, wherein one of the treatment configurations removes biofilm from the conductive deposition monitoring surface, and the other treatment configuration removes inorganic scale deposition from the conductive deposition monitoring surface.

  • Publication number: 20130256237
    Abstract: 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.

  • Publication number: 20110052655
    Abstract: A method for controlling protozoa trophozoites and cysts wherein one or more biocides or non-biocidal agents are encapsulated within a micro-capsule or nano-capsule and then introduced into an aqueous system. The micro-capsule or nano-capsule has an exterior composition adapted for digestion by the protozoa. A vesicle for controlling protozoa trophozoites and cysts is also provided.

  • Publication number: 20080274929
    Abstract: 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.
