Cycles of concentration are defined as:

Impurity in the Cooling Tower
Impurity in Feed Water


Calcium Cooling Tower 100 200 45
Calcium in Feed Water 20 50 15
Cycles of Concentration 5 4 3

Cycles of concentration are important as the higher the cycles of concentration the lower the bleed will be since bleed as a percentage of feed water     =     1/ cycles

Total Water used in a Cooling Tower = Evaporation + Bleed + Drift + Leaks

There are about 1.5 gallons of water evaporated / tn of cooling. If we are running a 1000 Tn system let’s examine the impact of cycles on annual antiscalant usage.
