Highly hydrophobic oil−water separation membrane: reutilization of waste reverse osmosis membrane

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 10,   Pages 1606-1615 doi: 10.1007/s11705-022-2200-0

Abstract: increasing applications of seawater desalination technology have led to the wide usage of polyamide reverseosmosis membranes, resulting in a large number of wasted reverse osmosis membranes.In this work, the base nonwoven layer of the wasted reverse osmosis membrane was successfully modifiedinto the hydrophobic membrane via surface deposition strategy including TiO2 and 1H,1H,2HThis work might provide a new avenue for recycling the wasted reverse osmosis membrane used in oily wastewater

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 6, doi: 10.1007/s11783-018-1047-6

Abstract:

MABR exhibits excellent TN removal performance for treating ROC with low C/N ratio.

Operating conditions should be properly controlled to achieve optimal TN removal.

Denitrifying bacteria and NOB are proved notably inhibited by high salinity stress.

The TN removal rate remains over 70% when the NaCl addition amount is below 20 g/L.
