Water treatment for cooling systems has three primary objectives: corrosion, deposition and microbiological control. System components with high temperatures on heat-transfer surfaces are most vulnerable to inorganic scaling. Heat exchangers that have process leaks are susceptible to organic fouling from poor microbiological control. Similarly, components with high-surface temperatures on heat-transfer surfaces are the most vulnerable to corrosion. Corrosion can occur under inorganic deposits through differential aeration and under organic deposits - microbiological-induced corrosion (MIC) - due to the acidic nature
