cooling towers

Cooling towers receive significant benefits from application of a Zeta Rod™ system:

• Elimination of chemical water treatment,
• Reduced blow-down and operation at higher cycles of concentration without scaling,
• Elimination of biofouling, and
• Excellent corrosion protection.

Airborne dust, pollutants, chemicals, and organic materials such as pollen, leaves, spores, and microorganisms that continuously innoculate the cooling tower water system with potentially troublesome agents.

The water circulating in the tower typically contains inorganic salts such as calcium carbonate, calcium sulfate, silica, and other components that can form scale, interfering with the passage of air and water in the tower.

As water evaporates from the tower, these contaminants become more and more concentrated, increasing the likelihood of deposit formation.

Installation of a Zeta Rod system in the water system of a cooling tower prevents deposit formation and stops the proliferation of algae, fungi, bacteria and other microbes.

Because particulate and suspended material does not attach to wetted surfaces, and because biological activity is suppressed, corrossion rates are typically less than 2 mils/year for mild steel and less than 1 mil/year for copper. The figure below shows corrater (electronic corrosion measurement) data for the cooling tower of a glass bottle manufacturing facility with a Zeta Rod system installed in the tower sump.
