Advanced treatment for impaired water supplies: when advanced oxidation systems are the best option

As drought becomes pervasive around the world, many water suppliers are turning to water supplies once avoided – contaminated surface waters and groundwaters and wastewater. These water supplies are now a valuable part of a sustainable water supply; however, advanced treatment with advanced oxidation processes (AOPs) is typically needed to address trace contaminants in these supplies. This paper will address the following questions: 1) What is the best AOP technology for a given application? 2) Are there oxidation byproducts of concern? 3) What is the best peroxide quenching method? 4) How cost competitive are AOPs?
