“…The above example indicates that the concentrations of the monomer solutions should also be properly adjusted. It must also be pointed out that the changes in other variables such as substrate properties, aqueous/organic solution properties, reaction time and curing time during interfacial polymerization and types of nanofillers could lead to different outcomes [28][29].…”

Thin film nanocomposite (TFN) membranes containing 0.05 or 0.10 w/v% functionalized titanate nanotubes (TNTs) in polyamide selective layer were prepared via interfacial polymerization of piperazine (PIP) and trimesoyl chloride (TMC) monomers. Nanomaterials were dispersed into the monomer solution using two different approaches. In the first one, the functionalized TNTs were dispersed into the amine aqueous solution, while in the second approach the same nanomaterials were dispersed in TMC organic solution. The TFN membranes were characterized and compared with a control thin film composite (TFC) membrane to investigate the effect of nanofiller loadings and the fabrication approach on membrane properties. Results showed that introducing nanofillers into the organic phase was more effective to synthesize a TFN membrane of greater separation performance as the use of rubber roller to remove aqueous solution from the substrate surface could cause the loss of a significant amount of nanofillers, which further affected the polyamide layer integrity. It was also found that incorporation of high nanofiller loading tended to interfere with interfacial polymerization and weaken the bonds between monomers blocks, resulting in poor polyamide-nanotubes integrity. Compared to the TFC membrane, the TFN membrane made of 2% PIP and 0.15% TMC with 0.5% nanofiller incorporation could achieve greater water flux (7.5 vs 5.4 L/m 2 .h.bar) and Na2SO4 rejection (96.4% vs 86%) while exhibiting higher resistance against the fouling by protein and dye.

“…In the IP process, the asymmetric membrane surface is modified by coating with one or more thicker layers with smaller pores. The strong cross-linked bonding between piperazine layer and aromatic polyamide has successfully improved the permeability, selectivity and mechanical strength of the asymmetric membrane [14,17]. In addition, the advantages of PA membranes are relatively higher flux than other NF membranes, higher thermal stability and heat recovery.…”

“…Most TFC membranes are made with a porous, highly permeable support such as polysulfone, which is coated with a cross-linked aromatic polyamide thin film. 65 The coating -also sometimes referred to as the active layer -provides the solute rejection properties while the support provides the mechanical stability. The typical coating is made by interfacial polymerization to create a 100-200 nm thick polyamide coating exemplified by the reaction between m-phenyl diamine and trimesoyl chloride monomers.…”

In recent years, membrane technology has been widely used in wastewater treatment and water purification. Membrane technology is simple to operate and produces very high quality water for human consumption and industrial purposes. One of the promising technologies for water and wastewater treatment is the application of forward osmosis. Essentially, forward osmosis is a process in which water is driven through a semipermeable membrane from a feed solution to a draw solution due to the osmotic pressure gradient across the membrane. The immediate advantage over existing pressure driven membrane technologies is that the forward osmosis process per se eliminates the need for operation with high hydraulic pressure and forward osmosis has low fouling tendency. Hence, it provides an opportunity for saving energy and membrane replacement cost. However, there are many limitations that still need to be addressed. Here we briefly review some of the applications within water purification and new developments in forward osmosis membrane fabrication.
