Increasing the treatment levels of potable makeup water is an allowable method to increase cooling
tower cycles of concentration. This is because treating the makeup water can help control the
buildup of minerals and other impurities, allowing the system to operate more cycles before
requiring blowdown.
Reference: The LEED v4.1 O+M reference guide and other LEED resources emphasize the importance
of water treatment to manage cycles of concentration in cooling towers. Proper treatment helps
maintain water quality and efficiency, which is crucial for achieving higher cycles of concentration
without causing scale and corrosion problems1.
