Efficient removal of organic contaminants in real shale gas flowback water using Fenton oxidation assisted by UV irradiation: Feasibility study and process optimization

The treatment of high concentration wastewater in the natural gas processing industry

“…[8][9][10][11] Ozone (O 3 ) and its derivative hydroxyl radicals (cOH) possess remarkable electron affinity and oxidative potential, ranking second only to Fluorine. [12][13][14] The O 3 molecule can directly or selectively react with water impurities and undergo decomposition via a chain reaction mechanism, generating cOH. 15,16 The O 3 /H 2 O 2 oxidation process, derived from the development of O 3 oxidation process, has promising potential in advanced wastewater treatment owing to its non-selectivity and absence of secondary pollution.…”
