A review of advanced oxidation process towards organic pollutants and its potential application in fracturing flowback fluid

Environ Sci Pollut Res Int. 2023 Apr;30(16):45643-45676. doi: 10.1007/s11356-023-25191-6. Epub 2023 Feb 24.

Abstract

Fracturing flowback fluid (FFF) including various kinds of organic pollutants that do harms to people and new treatments are urgently needed. Advanced oxidation processes (AOPs) are suitable methods in consideration with molecular weight, removal cost and efficiency. Here, we summarize the recent studies about AOP treatments towards organic pollutants and discuss the application prospects in treatment of FFF. Immobilization and loading methods of catalysts, evaluation method of degradation of FFF, and continuous treatment process flow are discussed in this review. In conclusion, further studies are urgently needed in aspects of catalyst loading methods, macromolecule organic evaluation methods, industrial process, and pathways of macromolecule organics' decomposition.

Keywords: AOPs; Fracturing flowback fluids; Organics; Waste water management.
