Aerobic SMBR/reverse osmosis system enhanced by Fenton oxidation for advanced treatment of old municipal landfill leachate

- Combined Fenton/SMBR/RO process was set up to effectively treat landfill leachate.
- Fenton can remove organic pollutants and improve leachate biodegradability greatly.
- SMBR behaved differently in EPS, zeta potential, particle size and structure of flocs.
- Improvement of flocs' properties after Fenton treatment alleviated membrane fouling.
- RO provided high quality filtration and membrane fouling can be effectively reduced.
