    摘要: The inventors have discovered a new method of treating paper machine white water aqueous systems and surfaces in the paper machine white water aqueous systems that prevents or inhibits the adhesion of bacterial cells to the surfaces and thereby controls the biological fouling of the surfaces. The process comprises adding to the aqueous system an adhesion-inhibiting amount of vinyl cationic polymer. This method effectively inhibits the adhesion of the bacterial cells to exposed surfaces without killing the fouling organisms and also without harming non-target organisms. In addition, the method of the present invention advantageously does not cause the formation of harmful substances in the effluent from the systems treated.

    摘要: A fouling monitor and method for sensing fouling in commercial waters and for differentiating between microbiological fouling and chemical fouling, which includes a dissolved oxygen probe disposed in a slip stream of water and means for providing an abundance of oxygen and nutrient to the microbial activity whereby a decrease in dissolved oxygen level is sensed due to the increased respiration of the microbes when microbiological fouling occurs. A polyester screen is mounted over the sensing end of the dissolved oxygen probe to promote microbiological fouling by providing a means for engaging the microbes and to enhance differentiation between the biological component and the non-viable/chemical component.

    摘要: A system and a method are provided for detecting and monitoring changes in frequency in a process stream. At least one probe is placed in the process stream that is capable of detecting a change in frequency due to a build-up of mass on the probe from scale, corrosion, biofilm or the like in the process stream. A processor receives the signal produced by the probe to produce an output signal indicative of the change in frequency which is proportional to mass detected by the probe. A feeder is capable of feeding a product into the process stream as a result of the detected change in frequency of the probe to combat the mass build-up from scale, corrosion, biofilm or the like in the process stream. The system and method are further capable of measuring anti-scalant, corrosion inhibitor, biocide efficacy and controlling product feed into the process stream based on the determined efficacy.

    摘要: The product selection test is developed for rapid determination of the presence of synergistic blends of the biocide or the presence of biocide blends in contaminated waters. The method uses a reduction oxidation dye system, supplied nutrients, admixtures of one or more biocides or blends thereof and incubation times and temperatures providing for a variation of color changes of the dye system. Industrial waters such as pulp and paper waters contaminated with microbes can be tested by this rapid method of determining the presence of synergistic blends of anti-microbial agents.
