How do you treat cooling tower water?

Ion Exchange & Water Softening Water hardness, or the presence of minerals in the water (and especially magnesium, calcium, and iron), can dramatically affect the lifespan and efficacy of your cooling tower. You can soften your water by inserting lime, or you can opt for a resin.

What chemicals are used in cooling tower water treatment?

Here are the main chemicals that are frequently used in cooling tower water treatment:

  • Corrosion and Scale Inhibitors.
  • Algaecides and Biocides.
  • pH Adjusters.

What is a cooling tower water treatment system and how does it work?

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.

Which water is used in cooling tower?

The water consumption consists on the control of the make-up water, the blowdown water and the evaporated water quantities. These three waters determine the cycles of concentration that can be reached in the cooling tower.

Why h2so4 is used in cooling tower?

Sulfuric acid has been used to reduce alkalinity in cooling towers for decades. By neutralizing carbonate alkalinity with acid, scaling potential is reduced on heat exchangers, and often systems can be run with less water.

Which chemical is best for cooling tower?

Chlorine dioxide – This chemical can be used as a disinfectant to destroy microorganisms and prevent recurring growth.

What is TDS cooling tower?

The TDS concentration of cooling tower water and the pH values depend on its original sources and on the cycle number of circulations inside the building. The TDS values change from 300 to 1,200 ppm.

How can we maintain TDS of cooling tower?

Possible solutions

  1. Improved feed water filtration.
  2. Higher-quality side-stream filtration.
  3. Increased cycle of concentration (depending on quality of makeup and circulation water—not always the right solution)
  4. Maintaining better makeup water chemistry by removing scale forming and corrosion causing impurities.

What should be the TDS of cooling tower?

What is the use of Sulphuric acid in cooling tower?

Sulfuric acid has been used to reduce alkalinity in cooling towers for decades. By neutralizing carbonate alkalinity with acid, scaling potential is reduced on heat exchangers, and often systems can be run with less water. However, handling large quantities of acid can be hazardous and requires special permitting.

What is COC water?

What is COC meaning? COC or the Cycles Of Concentration is an abbreviation, used when talking about cooling water or cooling tower water. The COC specifies, how often a fresh water added into the loop, can be used or pumped around, before the water has to blown down or bleed off from the cooling tower.
