94-12: The Effect of Process Leak Contaminants on Biocidal EfficacyAbstract: 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

Many large power/petrochemical plants have older cooling towers which are in need of major repairs but shutting down these towers will result in large production losses

yet it is common for industrial customers to allow the "least common denominator" in cooling tower materials and preservative treat­ment to be furnished

Some of the standards which will have their important points reviewed include: Redwood-Lumber Specifications
