The impact of MOF feasibility to improve the desalination performance and antifouling properties of FO membranes

Abstract

In this study, a hydrophilic metal–organic framework (MOF) was applied to improve the performance of a cellulosic membrane for forward osmosis (FO) desalination application.

Comparison of the intrinsic parameters (A, B and S) of a forward osmosis membrane using pressurized and non-pressurized methods

“…4. Comparing the two results at different orientations, the measured water It is interesting to note that the water flux observed in ALDS is lower than ALFS in this study, which is contradict to what has been established earlier [27][28][29]. This inconsistency may be due to the intrinsic values of the membrane or the hydrodynamic factor during the test.…”

Physical modification of polymeric support layer for thin film composite forward osmosis membranes by metal–organic framework‐based porous matrix membrane strategy

“…After extensive investigation on structural and transport parameters of all fabricated TFC membranes, it is very important to use the characteristic curve for selecting the best membranes . This curve presents a trade‐off between the ratio of J w on theoretical osmotic pressure ( J w /Δ π theo ) and J w / J s (Figure ).…”

Cu-BTC Metal−Organic Framework Modified Membranes for Landfill Leachate Treatment

“…As can be seen, the addition of the MOF has an effect on both the surface and the sublayer, for example, the finger-like pores of modified membranes are longer and wider than the neat membrane. The good affinity of Cu-BTC particles to water media [48,49] changes the kinetic and thermodynamic features of the coagulation process and speed up the exchange rate between solvent and non-solvent during the precipitation process [50,51]. Consequently, a thin skin layer at the top and porous sub-layer at the bottom with longer and wide finger-like pores were created, due to the hydrophilicity and good dispersion of Cu-BTC [52].…”

“…Consequently, a thin skin layer at the top and porous sub-layer at the bottom with longer and wide finger-like pores were created, due to the hydrophilicity and good dispersion of Cu-BTC [52]. The high affinity of MOF particles to the water bath during phase inversion led to a particle transfer to the membrane top layer and assembled in the water-polymer interface to reduce the interfacial energy [49]. MOF particles can obviously be seen in the surface of M-2 membrane (bright point in Figure 2f).…”
