Polymer-flooding produced water treatment using an electro-hybrid ozonation-coagulation system with novel cathode membranes targeting alternating filtration and in situ self-cleaning

•A novel CM-E-HOC was firstly put forward to apply in produced water treatment.•The CM-E-HOC showed higher removal efficiency than the CM-EC processes.•Both reversible and irreversible membrane fouling were mitigated in the CM-E-HOC.•Alternating filtration in the CM-E-HOC can realize higher water pr...
