It may seem ironic that ozone can be beneficial. Yet, ozonation is one of several water-treatment methods available for ensuring safe drinking water. It is used in municipal water-treatment systems as well in home-water systems. While no method of water filtration will remove all toxins, ozonation has its place among the options available for treating water.
Definition
Ozone is chemically unstable. In nature, it is created by a chemical reaction between oxygen and ultraviolet radiation. Ozonators replicate this reaction and inject ozone into a water source for treatment. Ozone is created either through the use of an ultraviolet light or an electronic corona discharge device before being delivered into the water, according to Hot Tub Essentials.
Benefits
There are several advantages to using an ozonation system. Ozone can effectively destroy disease-causing bacteria such as E. coli, viruses and other biological contaminants, according to the National Sanitation Foundation. It can also break down many organic chemicals. Ozone can aid in the removal of other chemicals, such as iron and sulfur. Ozonators operate quickly and can treat large quantities of water.
Uses
Because of its bacteria-destroying properties, ozonation is widely used for treating water in home and commercial spas. This benefit also lends itself to use for treating and processing food. Because ozonation does not add any odors or tastes to water, bottled-water manufacturers use it to treat their products, according to the U.S. Food and Drug Administration.
Disadvantages
While its benefits are commendable, ozonation has several drawbacks. Unlike faucet mounts or filters, ozonators require electricity in order to operate. If you suddenly find yourself without power, you may also find yourself without safe drinking water. The process of treating water with ozone creates some harmful byproducts including bromate. Ozone stimulates a chemical reaction that creates this chemical. According to the U.S. Environmental Protection Agency, long-term exposure to bromate may increase the risk for cancer in some individuals. Bromate is among the contaminants regulated by the EPA.
Considerations
Bromate concentration is affected by the amount of bromide present in the water, according to the National Sanitation Foundation. Bromide is naturally found in drinking water sources and presents no harm in this chemical form. If you use an ozonators in your home, you will likely need a secondary water-treatment device, as ozonation will not treat all water-quality issues. Activated carbon filters can provide a complementary water-treatment method.
