Applications of Advanced Oxidation for Wastewater Treatment
نویسنده
چکیده
Novel advanced oxidation processes (AOPs) show great promise for application in many wastewater treatment areas. AOPs are an emerging technology that may be employed for specific goals in wastewater treatment. These AOPs utilize the very strong oxidizing power of hydroxyl radicals to oxidize organic compounds to the preferred end products of carbon dioxide and water. Advanced oxidation has been used to treat wastewater from groundwater remediation pump-and-treat systems, manufacturing facilities, domestic wastewater treatment plants, and others. But advanced oxidation has not been widely applied yet because the chemical processes behind advanced oxidation is not completely understood. Specific operating conditions and reactant doses are necessary for complete mineralization of the organics, and for effective wastewater treatment.
