Before a new water main or one that has recently under gone repair can be placed back into service, it must be flushed and disinfected. The conventional approach is to use high concentrations of chlorine for an extended period of time to kill the bacteria living in the biofilms attached to the water main surface. […]

Study Shows Electrolysis and Volatilization Can Mitigate Bromate Formation in Drinking Water
A recent study in the Journal Ozone Science and Enginnering has shown that electrolysis followed by volatilization can remove Br from drinking water and as a result lower the formation of bromate from ozone water treatment. This is an important issue since a large number of water sources contain Br ion. Ozone can react under […]
US EPA Launches App to Let Users Check Waterway Health
The US EPA has launched a new app and website that let’s users check on the health of waterways anywhere in the US. It provides information on thousands of lakes, rivers and streams across the US. The release of the website corresponds to the 40th Anniversity of the Clean Water Act. The app uses GPS […]
Santa Barbara to Complete Upgrade to Ozone
The City of Santa Barbara’s Cater Water Treatment Plant is being upgraded in response to stricter federal drinking water regulations. The $20 million ozone water treatment project is about 80 percent complete. The work should be completed by the end of January. Ozone will replace chlorine in the pre-treatment of water at the plant. Besides […]
Dallas Experienced Problems with Ozone System
Dallas Water Utilities experienced an outage at the Elm Fork Drinking Water Treatment Plant on December 10. As a result, the facility failed to meet the minimum treatment technique requirements that day when its water system failed to properly disinfect the drinking water for a period of more than four hours. DWU has indicated that […]
Dangers of Bromate in Drinking Water May Be Overstated
Ozone can react with bromide ion to form bromate. Currently, the USEPA has a limit of 10 micro grams per liter for ozone in drinking water. This level has been extended to other water treatment applications, for example, ground water remediation. The USEPA is considering lowering the allowable limit for bromate to 5 micro grams […]
