Cooling tower water treatment system

Cooling tower water treatment system

A cooling tower water treatment system is an arrangement of technologies that remove damaging impurities from your cooling tower feed water, circulation water, and/or blowdown. The specific configuration of your system will depend on several things, including: .

  • What type of cooling tower you have (open circulating, once-through, or closed loop)
  • Quality of your feed water
  • Manufacture-recommended quality requirements for the cooling tower and equipment
  • Chemistry/makeup of your circulatory water
  • Regulatory requirements for discharge
  • Whether or not blowdown will be treated for reuse in the cooling tower
  • Type of heat exchanger
  • Cycle of concentration

Makeup water, or the water replacing bleed and evaporated and leaked water from the cooling tower, is first drawn from its source, which could be raw water, city water, city-treated effluent, in-plant wastewater recycle, well water, or any other surface water source. Depending on the quality of this water, you may or may not need treatment here.

Specialty water treatment Chemicals are typically the use of chemicals, such as: corrosion inhibitors (to protect metal components), algaecides and biocide to reduce the growth of microbes and biofilms, scale inhibitors to prevent contaminants from forming scale deposits. Thorough treatment prior to this stage can help reduce the amount of chemicals needed to treat water at this point in the process, which is ideal considering many chemical treatments can be expensive.
