Abstract: An alternative oxidizer, chlorine dioxide is used in a plastic film manufacturer's cooling water systems to control microorganisms. As a result of the process, the water is contaminated with percentage amounts of ethylene glycol and acid aldehyde. These serve as nutrients for unbridled microbial growth leading to sever operating problems in the condensers and cooling towers. A discussion of the resulting under deposit corrosion, as well s the successes, failures and limitations of various biocides are included in this documentation of an extremely challenging cooling water treatment applications.
