Abstract: An effective amount of at least one second bacteria may be added to a wastewater stream within a water treatment system. The wastewater stream may have or include an aqueous-based fluid, a first bacteria and organic acids. The second bacteria may be or include, but is not limited to facultative bacteria, spore-forming bacteria, phenol degrading bacteria, denitrifying bacteria, organic acid-degrading bacteria, high temperature bacteria, and combinations thereof. The addition of the second bacteria the wastewater treatment system may at least partially reduce the amount of the organic acids within the wastewater stream as compared to an otherwise identical wastewater stream in the absence of the second bacteria.

Abstract: An effective amount of at least one nitrogen-containing compound may be added to a wastewater stream within a water treatment system. The wastewater stream may have or include an aqueous-based fluid, a first bacteria, a second bacteria, organic acids, and combinations thereof. The first bacteria may be or include, but is not limited to, filamentous bacteria, Zoogloea bacteria, and combinations thereof. The second bacteria may be or include, but is not limited to facultative bacteria, spore-forming bacteria, phenol degrading bacteria, denitrifying bacteria, organic acid-degrading bacteria, high temperature bacteria, and combinations thereof. The addition of the nitrates to an anoxic zone within the wastewater treatment system may at least partially reduce the amount of the first bacteria within the wastewater stream as compared to an otherwise identical wastewater stream in the absence of the nitrogen-containing compound(s).

Abstract: Waste water may be treated by introducing activated carbon into a biological oxidation system as a slurry wherein: (1) the slurry is stable as compared to a conventional activated carbon slurry; (2) the activated carbon within the slurry retains at least 85% of its absorptive capacity; and (3) the activated carbon is immediately available for absorbing organic compounds when introduced into the biological oxidation system. The method is particularly useful for treating upset conditions. These slurries may also be used for treating other types of water to remove compounds that can be absorbed by activated carbon. Exemplary of such water types are process water and run-off water.

Abstract: A method for identifying contaminants within a liquid hydrocarbon media containing contaminants includes adding an optical tag to a water wash, adding the tagged water wash to the liquid hydrocarbon media, emulsifying the liquid hydrocarbon media and analyzing the contaminants in the hydrocarbon media with a microscope. Methods for removing contaminants and evaluating treatment are also provided.

Abstract: Methods for inhibiting the attachment of microbes to surfaces in aqueous systems are disclosed.

Abstract: Methods for inhibiting the attachment of microbes to surfaces in aqueous systems are disclosed. Copolymers of a tannin and a cationic monomer are added to aqueous systems, such as papermaking and cooling water systems, to inhibit microbial attachment to surfaces which cause slime formation problems.

Abstract: A method for treating the microbial slime that is generated in industrial water systems by adding to the water a combination of enzymes specific to the numerous saccharide units that make up the exopolysaccharide layer. These enzymes comprise galactosidase, galacturonidase, rhamnosidase xylosidase, fucosidase, arabinosidase and .alpha.-glucosidase.
