The failure of a corrosion control program in a closed cooling water system coincided with the use of reclaimed sewage water and the contamination of the system with oil. Other problems were increased corrosion rates, downward pH excursions, increased fouling by corrosion by-products, and increased microbiological activity in the system. The major cause of corrosion was microbiological in origin. The unsuccessful use of a biocide led to the initiation of a full-scale microbiological investigation. The nature of the microflora was determined, biocide selection tests made, and an effective control treatment program initiated. Chromate corrosion treatment was replaced by a coordinated program using an organic filming corrosion inhibitor, a polyacrylate/phosphonate dispersant, and a combination of biocides.
