  • Publication number: 20160280570
    Abstract: Methods and compositions for dispersing a biofilm in an aqueous stream using fatty acids are disclosed. The fatty acids may have the formula: R1-R5—CH3 wherein R1 is an aryl or arylalkyl, —COR2, —COOR2, or —CONR3R4, —PO3(R2)3; R2 is H, an alkyl, an aryl or arylalkyl, or a halide; R3 and R4 may be the same or different and are H, a hydroxyl, an alkyl, an aryl or arylalkyl, a halide, or a sulfo (sulfonic acid group); R5 is an aliphatic chain having 2-30 carbon atoms and at least one double bond; and wherein when R1 is —COOH and R5 has eight carbon atoms and the FA has only one double bond, such double bond is not on the number 2 carbon.

  • 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: 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.
