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.

Bacterial additives for biological and/or chemical contaminants within water-based fluids

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,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).

Nitrogen-containing compounds for bacterial control in water based fluids

Methods for inhibiting the attachment of microbes to surfaces in aqueous systems are disclosed. Tea extracts and/or tannins are added to aqueous systems, such as papermaking and cooling water systems, to inhibit microbial attachment to surfaces which cause slime formation problems

Methods for inhibiting the production of slime in aqueous systems

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.

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.
