Ozone Use in Cooling Towers


bullet 3,125 times more germicidal than chlorine
bullet eliminates the use of chemicals except for pH balancing
bullet ends discharge liabilities and chemical storage record keeping
bullet destroys all types of microorganisms instantly
bullet minimizes condenser fouling
bullet decomposes organic waste by oxidation
bullet removes existing calcium carbonate scale by destroying the biomass glue bonding agent
bullet low maintenance costs
bullet the most environmentally friendly oxidant
bullet no persistent chemicals or disinfectants in bleed - ozone breaks down to oxygen
bullet reduces the corrosion rate of metals, including copper heat exchangers
bullet saves on energy costs by increasing the heat transfer efficiency of the chiller

Ozone reduces operating costs by:

bulletReducing makeup water to the cooling tower by permitting more cycles between blowdowns.
bulletEliminating the cost and problems in ordering, shipping, handling, storage, and disposal of regular chemicals.
bulletReducing power consumption by keeping the chiller heat transfer efficiency high through cleaner condenser tubes.

* Studies by Southern California Edison (SCE), NASA, Jet Propulsion Laboratory (JPL), and IBM have confirmed that ozonation is a viable alternative to multi-chemical treatment. Electricity savings of 20% or more were cited by SCE.
