Fouling of high efficiency film forming cooling tower fill is a major water problem facing the industry, especially the utility industry. The paper focuses on the three main processes responsible for fouling honey-comb PVC fill - water borne, e.g. silt, clay or other suspended solids; water formed, e.g. sparingly soluble minerals; and biological. Fouling mechanism is studied by examining the relationship of microorganism, extra cellular polymer, clay particles, and precipitates in the fouling process using laboratory and pilot cooling towers containing Munters Fill. The conclusions are verified with field data.
