Water Factory 21 (WF21), Orange County Sanitation District (OCSD), was dedicated in a 1977 and transforms secondary municipal wastewater into water that exceeds drinking water standards. In 1991, the Orange County Water District (OCWD) was granted a California Department of Health Services permit to inject 100 percent reclaimed wastewater into a potable water aquifer without […]

Illinois Country Adopts Advnaced Oxidation for Disinfection, Taste and Odor Control
The Otter Lake Water Commission has submitted is plan, as well as a loan application for nearly $2 million, to the Illinois Environmental Protection Agency (IEPA) public water supply loan program. The Otter Lake commission is responsible for water treatment and for the distribution systems that transmit water to 467 individual and nine wholesale customers […]
Advanced Oxidation Process Demonstrates Taste and Odor Improvment in Va Drinking Water
Virginia American Water conducted a small-scale plant trial that used advanced oxidation, ultraviolet light and hydrogen peroxide to remove the taste and odor-causing compounds in the Appomattox River source water. The plant trial demonstrated that this method efficiently and effectively removed the compounds, even at high levels. Because of record temperatures of the 2010 summer, […]
San Diego Uses Advanced Oxidation to Recycle Wastewater
In summer 2011, the City of San Diego opened the Advanced Water Purification (AWP) Facility, a small-scale, state-of-the-art facility that purifies one MGD of recycled water. The facility is one component of the City’s Water Purification Demonstration Project that is examining the safety and cost of purifying recycled water. San Diego is examining water purification […]
Ozone Can Reduce Chemical Use in Citrus Storage and Distribution
Economic losses caused by post harvest diseases are an important problem in citrus plants. Most spoilage in oranges in storage and distribution is caused by penicillium digitatum. Currently this is controlled by the application of synthetic chemical fungicides. These compounds have environmental impact and their use may be reduced in the future by regulation. Juice […]
Spanish Research Group Evaluating Advanced Oxidation for Removal of Emerging Pollutants from Wastewater
The national environmental research group in Spain ‘Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas’ CIEMAT is currently working in one important on-going project (EDARSOL) to develop an integrated process for removing emerging pollutants in waste water through the combination of biological treatment with advanced oxidation processes (AOPs) based on solar photo catalysis (TiO2, foto-Fenton) and […]
Advanced Oxidation Process to be Tested in Ontario to Remove Micro Pollutants from Waste Water
The province of Ontario is assisting the York region develop solutions to protect and to provide safe, reliable clean drinking water. The new Showcasing Water Innovation program supports projects with innovative and cost-effective ways to improve drinking water, waste water and storm water systems. Ontario has the highest standards for clean water in North America […]
Cottonwood, Az Plans to Reclaim Wastewater for Drinking Water Using Advanced Oxidation
Cottonwood, AZ is planning on using reclaimed wastewater as a drinking water source sometime in the next15 or 20 years. The city plans to build an $8 million, wastewater treatment plant capable of removing many trace synthetic compounds via advanced oxidation using ozone and hydrogen peroxide. The focus is on pharmaceuticals which have recently become […]
Advanced Oxidation Treats Contaminated Ground Water Near Tucson
For 25 years, TCE-polluted groundwater has been pumped for treatment from an old Air Force Plant near Tucson where chemicals were dumped by weapons-systems manufacturers from the 1940s until the 1970s. Discovered in 1981, the groundwater contamination remains at very high levels in areas of the 1,300-acre site. Some monitoring wells still show pollution at […]
