What is cycle of concentration in cooling tower?

An important concept related to Cooling Towers is the Cycles of Concentration (also known as Cycles or Concentration Ratio). As water evaporates from a Cooling Tower it leaves behind dissolved solids. These dissolved solids will therefore increase in concentration in the process water, until there is a Blow-down.Click to see full answer. Similarly, what is meant by cycle of concentration in cooling tower?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.One may also ask, what is blowdown cooling tower? Cooling tower bleed-off/blowdown is the flushing of a portion of high mineral concentration cooling tower system water down the drain, while simultaneously replacing it with fresh water. This process dilutes the system water mineral concentrations that steadily increase due to water evaporation. how are cooling tower cycles calculated? A key parameter used to evaluate cooling tower operation is “cycle of concentration” (sometimes referred to as cycle or concentration ratio). This is determined by calculating the ratio of the concentration of dissolved solids in the blowdown water compared to the make-up water.What is cycle of concentration in boiler?Cycles of Concentration. “Cycles of concentration” refers to the accumulation of impurities in the boiler water. If the boiler water contains 10 times the level of impurities in the makeup water, it is said to have 10 cycles of concentration.
