In this paper, Fe/Ni catalyst was successfully applied in the treatment of the flowback fluid for the first time. The catalyst can improve the oxidation efficiency of electrolytic brine and reduce the viscosity of fracturing flowback during the treatment process. The effect of the Fe/Ni proportion on the catalytic performance was studied.

quality, as treatment is less effective on the early flowback compared to produced water. TOC and low ionic strength may be the reason early flowback is more difficult to treat. Also, chemical coagulation (CC) is more effective than EC at removing TOC and aluminum in early flowback water compared to EC, while EC is more effective at removing iron.
