Abstract: The effect of various process leak contaminants on the performance of eight water treatment biocides was evaluated. The contaminants included a high temperature oil, diesel fuel, a hydraulic fluid, ammonia, ethylene glycol, sulfide and the following gases: carbon dioxide, hydrogen, l-butane, and propane. The efficacy of each biocide was compared in the presence and absence of the contaminants. While the extent of deactivation varied with each biocide, all were affected by at least one of the contaminants.
