86-17: Evaluation of Industrial Biocides in Laboratory Model Cooling Towers Drift

86-17: Evaluation of Industrial Biocides in Laboratory Model Cooling Towers DriftCooling tower models were used to simulate industrial conditions and evaluate the efficacy of commercially available biocides against adherent (sessile) populations of microorganisms. The cooling tower parameters that were controlled included temperature, pH, cycles of concentration, blowdown rate, recirculation rate, and lighting. The treatment programs were evaluated on the basis of viable cell counts, biochemical monitors, scanning electron

which operates 30 condenser open cooling circuits in nuclear power plants in France

These include excellent control of microbial populations even at the elevated pH typical of cooling tower waters
