Water Ozonation

New water treatment goals for disinfection byproducts (DBP) and for microbial inactivation will increase the need to consider new disinfection technologies. Ozone is an attractive alternative. This technology has evolved and improved in recent years, thereby increasing its potential for successful application.

Ozone might be called an “orphan” disinfectant since it has worldwide a very low use in water treatment plants. Ozone (O3) is an extremely unstable gas. Consequently, it must be manufactured and used onsite. It is the strongest oxidant of the common oxidizing agents. Ozone is manufactured by passing air or oxygen through two electrodes with high

Advantages:

• Ozone is more effective than chlorine in destroying viruses and bacteria.
• The ozonation process utilizes a short contact time (approximately 10 to 30 minutes).
• There are no harmful residuals that need to be removed after ozonation because ozone decomposes rapidly.
• Produces no taste or odor
• Provides oxygen to the water after disinfecting;
• After ozonation, there is no regrowth of microorganisms,
• Requires no chemicals;
• Reacts with and removes all organic matter.
