  • What is a chemical treatment program for a cooling tower?
  • The chemical treatment program for these cooling tower systems (typically greater than 88 kilowatts [25 tons]) requires sufficient, regular testing as well as water and chemical control to protect the equipment in contact with the cooling water. Usually treatment includes control of scale, fouling, microbiological growth, and corrosion.
  • Should a cooling tower be chemically treated?
  • If the cooling tower is not chemically treated, the COC should be adjusted to be slightly less than the lowest allowable COC value based on all scale-forming water ingredients. The use of chemical treatment permits a higher COC, which is usually limited by either the chemical effectiveness or the water treatment control.
  • What is the evaporation rate of a cooling tower?
  • So, the evaporation rate in this example is 3,037 gpm, which is approximately 2 percent of the circulating water rate. As water evaporates in a cooling tower, dissolved solids (and suspended solids) remain behind. These solids concentrate and increase the scaling, corrosion, and fouling potential of the water.
  • What is a forced draft cooling tower?
  • 1.3.2 FORCED-DRAFT TOWERS. The term “forced draft” denotes that air is forced or blown by fans into the cooling tower and up through the flow of falling water in the cooling tower. Drift eliminators are installed to prevent water entrained in the air from leaving the system. 1.3.3 INDUCED-DRAFT TOWERS.
