Multi-cycle filtration tests demonstrated significant anti-irreversible fouling of the modified PVDF membrane. Specifically, all modified membranes reached almost 100% water flux recovery and maintained the initial fluxes constant in multicycle tests. Similar to much other research, this change was attributed to an increase in the surface hydrophilicity of the membrane. 6 Aluminum oxide nanoparticles The stability, availability, hydrophilicity, and suitable mechanical strength of aluminum oxide (Al2O3) nanoparticles make this inorganic material another option for preparing of nanocomposite membranes.

The incorporation of TiO2 nanoparticles into PA resulted in an increase in water flux owing to the enhancement of hydrophilicity in the membranes. 0 wt%, the optimum membrane performance was obtained together with strong mechanical properties. In more concentration of TiO2, the permeation flux increased and salt rejection decreased significantly. Moreover, the decrease in mechanical strength of the membranes resulted in easier peeling-off of the PA-TiO2 layer from PES substrate after the filtration experiment.

2 Clay nanoparticles Clay nanoparticles are another inorganic additive for enhancing membrane performance. Unmodified montmorillonites (NaþÀMMT) and Cloisite grades (modified MMT) are widely used nanofillers in the preparation of polymer nanocomposites. Montmorillonite contains phyllosilicate groups and possesses an octahedral sheet sandwiched between two tetrahedral sheets, forming a plate-shaped structure (with the average diameter around 1 mm) (Abdollahi, Rahmatpour, Aalaie, & Khanbabae, 2008; Xie, Tan, Liao, and Liu, 2010).
