Abstract
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.
