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 of the biological processes.

requires matching key characteristics of the system with the
various treatment programs and the users'
