Public Utilities for Bossier City, LA uses ozone to improve water quality for its customers.
Water is pumped from the Red River to a reservoir and from the reservoir to a water treatment plant where it undergoes treatment. During the treatment process, ozone is added to the water twice in order to eliminate any unpleasant tastes or odors. Ozone is used widely around the US for taste and odor control. It is typically cheaper than alternative methods such as powdered activated carbon or UV/peroxide. It also does not require any addition of chemicals or disposal of spent carbon.
The ozone also inactivates any virus causing organisms that may be present. Ozone can kill a wide variety of micro organisms including one not treatable with chlorine. Once the treatment process is complete, the water is pumped to the distribution system, which handles up to 24 million gallons daily.
