Wastewater Treatment Based on AOPs, ARPs, and AORPs

Dear Colleagues,

The pollution of organic wastewaters, such as dyes, phenols, and pharmaceuticals, is a serious environmental problem, and advanced oxidation processes (AOPs) are potentially sound techniques to degrade such contaminants based on the generation of reactive species that are powerful oxidants and can effectively degrade almost all stable compounds. In addition, AOPs have great advantages for the treatment of trace harmful chemicals such as environmental hormones, enabling the complete mineralization or decomposition of most organic materials. Furthermore, AOPs have good application prospects. AOPs can be divided into photocatalytic oxidation, catalytic oxidation, acoustic chemical oxidation, ozone oxidation, electrochemical oxidation, Fenton oxidation, etc.

However, recent advances have highlighted other advanced treatment processes (ATPs) as possible alternatives, such as advanced reduction processes (ARPs) and advanced oxidation–reduction processes (AORPs). They may remove contaminants that are not readily treatable by AOPs or offer better performance than the former. This Topic will collect some articles about the most common or promising ATPs for the removal of contaminants from water and wastewater and for their application.
