10 Questions
What can happen if impurities in cooling water are left untreated?
Increased operating costs and equipment failure
What are the sources of impurities in cooling water?
Avian waste, contact with the atmosphere, and raw make-up water
What problem can be caused by the deposition of solids (scaling) in cooling towers?
Corrosion
What leads to the deposition of solids (scaling) in condensers and on cooling tower evaporative surfaces?
Increased concentration of dissolved solids due to water evaporation
What does the degree of scaling primarily depend on?
Concentration of calcium and bicarbonate ions in solution and the pH of the cooling water

Corrosion product accumulation
What is the principal cause of steel corrosion in cooling towers?
Dissolved oxygen in the cooling water
What effect does acidity have on corrosion?
Encourages oxide formation on metal surfaces
What is a substantial threat found in cooling towers due to warm water, abundant sunlight, and an oxygen-rich environment?
Legionella bacteria growth
What can cause deterioration of wooden components in cooling towers?
Biological and chemical attack
