WHY DO COOLING WHY DO COOLING WATER PROBLEM EXIST ?WATER PROBLEM EXIST ?If cooling water left untreated , cooling If cooling water left untreated , cooling

water system provide an water system provide an environment where the four main environment where the four main cooling problems will exist:cooling problems will exist:

• CORROSIONCORROSION• SCALESCALE• FOULINGFOULING• MICRO BIOLOGICAL CONTAMINATIONMICRO BIOLOGICAL CONTAMINATION

Corrosion Control ConceptsCorrosion Control Concepts

The rate of attack by circulating cooling water The rate of attack by circulating cooling water on steel is a function of temperature and pH. It on steel is a function of temperature and pH. It increases with temperature and depression of increases with temperature and depression of pH. pH.

Corrosion protection follows two rules:Corrosion protection follows two rules:

High pH promotes scale and inhibits High pH promotes scale and inhibits corrosioncorrosion

Low pH inhibits scale and promotes corrosionLow pH inhibits scale and promotes corrosion
