92-09: Cleaning and Maintenance of Film Fill at Florida Power Corporation=

With wider use of highly efficient film and increasing interest in water conservation many cooling towers are experiencing plugging associated with the concentration of suspended solids from the make-up water. This plugging can reduce tower performance and in some utilities has necessitated load reduction. A reduction of plugging and maintenance of fill cleanliness has been achieved using low levels of polymeric dispersant. Product application, monitoring and performance evaluation are discussed.
