Process of Removing Organic Micropollutants Using Advanced Oxidation Techniques

Our environment is frequently being laced with organic pollutants owing to the anthropogenic activities, leading to varying concentrations of pollutants in the atmosphere. However, certain micropollutants, present in very low concentrations, can have severe implications for living organisms. This problem has been addressed by the development of remediation procedures to cleanse environment of micropollutants, where advanced oxidation processes (AOPs) emerged as the most potent technique. AOPs are oxidation-based methods used to remove micropollutants from water. Different processes such as ozonation, electrochemical AOPs, photocatalysis, and Fenton-based AOPs have been employed to remediate various kinds of micropollutants. AOPs offer several advantages over traditional removal techniques, making them a promising tool for micropollutant removal. This chapter highlights the working mechanisms and benefits of different AOPs such as ozonation, Fenton-based AOPs, etc. used to lower micropollutant levels. Further research into these technologies could prove valuable for environmental remediation.
