  5. 5. Details of Water-Cooling System • • • Cooling towers and Reservoirs Direct cooling to Dies Indirect cooling to oil through Heat Exchangers • Pre-treatment of Water through Water Softener • No Blowdown facility from bottom of water reservoirs
  6. 6. WHY DO COOLING WATER PROBLEM EXIST ? If cooling water left untreated , cooling water system provide an environment where the four main cooling problems will exist: • CORROSION • SCALE • FOULING • MICRO BIOLOGICAL CONTAMINATION
  7. 7. WHAT TYPE OF WATER CHARACTERISTICS AFFECT CORROSION • • • • • • Oxygen and other dissolved gases Dissolved or suspended solids Alkalinity or acidity Velocity Temperature Microbial activity
  8. 8. WHAT ARE THE EFFECTS OF THOSE PROBLEMS ? • Increased maintenance cost • Reduced heat transfer efficiency and therefore greater energy losses • Possible production cutbacks or shutdowns • Direct loss or abandon of plant & machineries
  9. 9. Methods of Prevention and Control of Scale • Removal of scale forming minerals by pre- treatment of makeup water. • Limiting the concentration of scale forming minerals by bleed control. • Replacing scale-forming minerals with soluble salts by acid dosing. • Controlling the scale forming process using scale-inhibiting chemicals.
  10. 10. Corrosion Control Concepts The rate of attack by circulating cooling water on steel is a function of temperature and pH. It increases with temperature and depression of pH. Corrosion protection follows two rules: High pH promotes scale and inhibits corrosion Low pH inhibits scale and promotes corrosion
  11. 11. PROBLEMS CAUSED BY MICROORGANISMS • • • HEAT TRANSFER EFFECTS FLUID FLOW EFFECTS CORROSION EFFECT
  12. 12. Parameters to Assess Water Quality • • • • • • • pH TDS Total Hardness Calcium Hardness Total Alkalinity LSI RSI
