Project Description

Cooling tower water analysis

Water is an important raw material in cooing tower industry due to the following properties:

  • Abundant
  • Readily available
  • Cheap
  • Easy to handle
  • high heat capacity
  • incompressible at normal conditions
  • does not decompose

Although, the disadvantage in using water is that it dissolves almost everything that it touches, including metals and stones.The process in which rain water falls to earth is called the hydrologic cycle. Water from rain becomes ground water, and enters bodies of water like ponds, lakes, rivers and oceans. This then evaporates back to the atmosphere and becomes rain again.

  • Rain dissolves all the minerals in three different forms:
    • Gases (oxygen and carbon dioxide)
    • Dissolved solids (dissolved minerals)
    • Suspended solids (clay,silt, dirt and oil)
  • There are two sources of water for industrial plant use. These waters are very different in the impurities they contain. Both water’s dissolving ability and the dissolved solids themselves are harmful to the cooling system equipment. Unless properly treated, water will cause scale, corrosion, and fouling.
  • Surface water
    • low dissolved solids
    • high suspended solids
    • abrupt changes in quality with seasons and weather changes
  • Ground water
    • high dissolved solids
    • low suspended solids
    • high iron and manganese content
    • low oxygen content, may contain sulfide gas
    • relatively constant quality and temperature
