Cooling Tower Water Management for UGBC LEED

For example, a 200 ton load cooling tower operated at 2 cycles will blowdown 5,300 gpd, while the same unit operated at 4 cycles will have a blowdown of just 1,767 gpd, a substantial decrease. There are three methods to increase cycles; acid feed to control pH, advanced scale prevention chemistry, or softening of the makeup water.

cooling tower calculation Water Technology Report

The bleed (also know as blowdown) controls the concentration of dissolved solids to keep them below their solubility limit. This prevents the formation of unwanted scale deposits. In order to prevent the tower from running dry, water that is lost by evaporation and bleed must be replaced by fresh makeup.
