ABSTRACT: The paper describes the four form of fouling and types of corrosion that can occur in cooling water systems. The mechanisms of which each occurs are describe and logically distilled down to all forms of fouling except inorganic crystallization scale formation lead to localized corrosion. Hence differentiation of generalized verses localized corrosion must be detected first then the resultant fouling values are assessed. Mitigation methods for these fouling and corrosion occurrences are also provided.
