We continue to scan news releases about new water treatment facilities employing ozone to improve water quality around the US and Canada. As we have noted in previous posts, ozone offers multiple benefits for drinking water treatment. Below is another example of a large water system switching to ozone water treatment.
Gilbert and Chandler Arizona have completed a new $102 MM treatment plant that will process 24 MGD of Colorado River water. Officials expect that residents will notice an improvement in the taste of the water.
The new plant uses a new process called “ballasted flocculation,” which uses ozone, sand and coal to remove bacteria and particles from the water within about 15 minutes. The process previously took about two hours and required much more space. The ozone is the facility is produced by ozone generators. Phoenix’s Lake Pleasant Water Treatment Plant converted to ballasted flocculation last summer.
