“…However, the values of the reversible (RFR) and irreversible (IFR) fouling ratios were equal to 15.58 and 23.09%, respectively. These rates indicated that 15.58% of the fouling can be removed via simple hydraulic cleaning, while 23.09% of the pore blockage was irreversible and could not be removed, except via chemical cleaning [ 43 ].…”

A novel natural phosphate/graphene oxide (GO) composite membrane was successfully fabricated using two steps: (i) silane chemical grafting and (ii) dip-coating of a GO solution. First, the low-cost disk ceramic support used in this work was fabricated out of Moroccan natural phosphate, and its properties were thoroughly characterized. The optimized ceramic support was sintered at 1100 °C following a specific heat treatment based on thermogravimetric analysis (TGA) and differential thermal analysis (DTA); it exhibited a permeability of 953.33 L/h·m2·bar, a porosity of 24.55%, an average pore size of 2.45 μm and a flexural strength of 22.46 MPa. The morphology analysis using SEM showed that the GO layer was homogenously coated on the crack-free Moroccan phosphate support with a thickness of 2.8 μm. The Fourier transform infrared spectrometer (FT-IR) results showed that modification with silane could improve the interfacial adhesion between the GO membrane and the ceramic support. After coating with GO on the surface, the water permeability was reduced to 31.93 L/h·m2·bar (i.e., by a factor of 142). The prepared GO/ceramic composite membrane exhibited good efficiency in the rejection of a toxic azo dye Congo Red (CR) (95.2%) and for a simulated dye effluent (87.6%) under industrial conditions. The multi-cycle filtration tests showed that the rejection rate of CR dye remained almost the same for four cycles. Finally, the flux recovery was also studied. After 1 h of water cleaning, the permeate flux recovered, increased significantly, and then remained stable.

A new low-cost composite ultrafiltration membrane made of polysulfone (PSf) and polystyrene (PS) blend was effectively achieved on the ceramic pozzolan support using dip-coating method. The effect of PS content (5-20 wt%) on membrane properties such as microstructure and filtration performances was investigated. The Fourier-transform infrared spectroscopy, nuclear magnetic resonance, and differential scanning calorimetry analyses confirm that the two polymers lead to physical blend. The morphology analysis shows that PSf/PS membrane layer is homogeneous and strongly adherent on the pozzolan support. Furthermore, the developed membrane was applied for filtration of direct red (DR80) and methyl orange (MO) solutions at a pressure of 3 bar. It was proven that the PS addition significantly enhances the rejection of the membrane companying with a decrease of permeate flux to meet the trade-off selectivity-permeability. The optimized PSf/PS membrane containing 5 wt% of PS has a water permeability of 24 L h À1 m À2 bar À1 , and could reject 91% and 76%, respectively for DR80 and MO. Beside the promising filtration results, the developed membrane is also low-cost thanks to using pozzolan support, and it could be consequently scaled up for the treatment of colored wastewater generated from textile industries.
