Cooling Tower

For industrial companies using a cooling tower for its facility, some type of cooling tower water treatment system is usually necessary to ensure an efficient process and long equipment service life. If cooling tower water is left untreated, organic growth, fouling, scaling, and corrosion can reduce plant productivity, cause plant downtime, and require costly equipment replacements down the road.

A cooling tower water needed arrangement of technologies that remove damaging impurities from your cooling tower feed water, circulation water, and blow-down. 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

Specific treatment processes vary depending on the requirements of the cooling tower and quality/chemistry of the feed and circulation water, but a typical cooling tower water treatment system will usually include the following steps:

ü  Cooling tower makeup water intake
ü  Filtration and ultra-filtration
ü  Ion exchange/water softening
ü  Chemical addition
ü  Side-stream filtration
ü  Blow-down treatment
