Fabrication of thin film composite membranes are common in Forward Osmosis (FO) process. Conventional thin films are fabricated using inter facial polymerization of meta phenyl diamine and trimesoyl chloride or their derivatives.
Can you suggest any alternatives for these thin films? Or any selective membrane layers that could be fabricated on a support layer for the effective salt/contaminant rejection in the seawater as well as in the waste water?
Dear Lijo,
In addition to the compounds you have mentioned in your very interesting question I list some publications that describe other materials with or without those you mentioned:
1-Journal of Membrane Science
Volume 471, 1 December 2014, Pages 381–391
Thin-film composite membranes formed by interfacial polymerization with natural material sericin and trimesoyl chloride for nanofiltration
Choumou Zhoua, b, Yalan Shia, b, Changsheng Suna, b, Sanchuan Yua, b, , Meihong Liub, Congjie Gaoc
Highlights
•TFC membranes for nanofiltration were prepared via IP between sericin and TMC.
Sericin–TMC composite membrane has smooth and thin selectively skin layer.
•
Membrane with a MWCO of 880 g/mol achieves a pure water permeability of 11.9 l/m2 h bar.
•
Rejection order of the TFC membrane is MgCl2
Dear Prof. Rafik,
This is awesome and I really appreciate.
Thanks and Kind Regards
Lijo
