    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： The invention is a polymeric powder that is useful as a flocculant and an associated process for preparing the same. The powder is prepared from spraying a liquid containing a water-soluble polymer into a fluidized bed of porous substrate particles. The spraying process coats the polymer onto the substate and removes the water through evaporative cooling. Polymeric powders prepared according to the invention rapidly dissolve in water and have improved viscosities over thermally dried polymer powders. Polymers that are useful in the invention include polyacrylamides, polyamines, and the like. The substrate is a porous material that can be either organic or inorganic, and typically has a porosity from about 1 to 1,000 m2/g.

    摘要： A method of making a solid water treatment product with an optimal rate of dissolution is described and claimed. A fluorescent tracer is used to determine the rate of dissolution of the solid water treatment product and the composition and method of manufacturing the solid water treatment product are adjusted as needed to make the rate of dissolution optimal. The solid water treatment product can be used in many industrial water treatment systems. When the solid water treatment product is used, the amount of solid water treatment product present in the water of the industrial water system can be determined, and adjusted, by using a fluorometer to measure the fluorescent signal of the fluorescent tracer present in the product and relating that measurement to the amount of product in the water itself.
