Abstract
The paper presents the data obtained by monitoring the cooling cycles of different industrial plants: ammonia plants, urea plants, power plants, fluid catalytic cracking units, desulphurization units. The typical bacterial populations for each system type and their action against the equipment are presented. The use of oxidizing and nonoxidizing biocides in cooling water treatment is emphasized.
