Cooling Towers

To clean and disinfect Cooling towers is vital to curtail the build-up of the nutrients and salts that help Legionella thrive.

Water that contains MgCO3 (Magnesium Carbonate) and CaCO3 (Calcium Carbonate) dissolve less in hot water than they do in cold water. Scum also is gathered within a cooling tower and with these 3 components, efficiency is highly reduced.

The required frequency and scope of regular cleaning and disinfection operations should be determined by an assessment of the fouling potential and based on inspection and the history of the water treatment control of microbial activity, scaling tendencies and other factors.

In clean environments with effective control measures it may be acceptable to extend the period between cleaning operations, provided you can demonstrate that system cleanliness is maintained.

Endoscope inspections are an effective method of demonstrating system cleanliness – click here for more information on endoscope inspections.
