Best Management Practice #10: Cooling Tower

Best Management Practice #10: Cooling Tower Management. Because dissolved solids enter the system in the make-up water and exit the system in the blowdown water, the cycles of concentration are also approximately equal to the ratio of volume of make-up to blowdown water.

2010-2-17 · The term "cycles of concentration" is defined as the ratio of the concentration of the boiler water to the concentration of the feedwater. Often referred to simply as "cycles," this ratio is inversely proportional to the total blowdown rate – cycles increase as blowdown decreases, and vice versa. So, by increasing his boiler water

BOILER REVERSE OSMOSIS – Nereus

Silica is a cycles limiting factor in the boiler. The more silica present in the boiler feed water, the lower the boiler cycles of concentration must be to avoid scaling. Running a boiler at cycles of concentration lower than could be the case results in significant waste of boiler make up water and more importantly fuel.

If ten cycles of concentration are permissible for a given boiler, then the concentration of chlorides should never exceed ten times that of the makeup water. For example, the makeup water chloride concentration is 10ppm so the boiler chloride concentration must never exceed 100ppm.
