Membrane Fouling – The Enemy of Forward Osmosis

Journal of Applied Membrane Science & Technology, 2021
Forward osmosis (FO) is an osmotically driven membrane separation process. It is potentially applied in various industries for nutrient recovery and water reclamation. Although FO showed a lesser fouling tendency than other pressure-driven membrane processes, the solutes in the feed solution would still deposit on the membrane surface, forming a ...

Membrane compaction in forward osmosis process [PDF]

Desalination, 2019
Abstract Membrane compaction is commonly observed in polymeric membranes when subjected to elevated hydraulic pressure, but was rarely discussed in forward osmosis (FO) processes, since there was usually little hydraulic pressure difference across the membrane.
