Effects of Ozonation in a Pool

          Cost Reduction

 Ø       Most commercial pools save 40 to 80 percent of their chemical costs

Ø       Recent installation in Alabama resulted in $22,815 (75 percent    reduction) in four months

Ø       Installation in Cancun of multiple corona units resulted in 50 percent savings at a 2 million gallon pool complex

 •          Reduced Shocking

 •          Eliminates Odors and Eye Irritation

 •          Improves water clarity and quality

 •          Enhances effectiveness of chlorine

How is Ozone Generated?

Corona Discharge:  Air which is dried, or air which is dried and passed through a device which concentrates oxygen from the air is run through a high voltage arc (5,000 volts and up).  The electrons in the field split some of the oxygen and the individual oxygen atoms recombine with normal oxygen to produce ozone.  Concentrations are typically in the one (1) to ten (10) percent range.

O2 + High Energy Electrons → O- +O-O2 + O-→O3

Prozone can offer standard or customized corona discharge units or treatment packages for almost any water treatment application

 Oxidation     

•          Ozone reacts with bather loading and combined halogens

•          Reduces contaminants to inert compounds or carbon dioxide and water

•          Oxidizes combined halogens

 Precipitation

      •  Ozone removes metals (iron, manganese, zinc, copper, etc.)

      •  Oxidized organics also precipitate

      •     Filtration and clarification are enhanced by precipitation

 Sanitation/Disinfection 

•          Ozone is the most powerful disinfectant available

•          Rapidly kills bacteria and viruses
