A B S T R A C TThe inherent hydrophilic nature of chitosan has gained significant attention with respect to its application in water treatment processes. This study was aimed to synthesize chitosanglycerol (CSG) membranes for microfiltration (MF) applications in wastewater treatment via the solution casting and solvent evaporation technique. CSG membranes were prepared in the ratios 2:1, 3:1, and 4:1 and were cross-linked with phosphoric acid in the presence of ethanol. The synthesized membranes were characterized by tensile strength, swelling, Fourier transform infrared spectroscopy-attenuated total reflectance and Scanning electron microscopy studies to investigate their structural properties. The porosifier glycerol had a great influence on the tensile strength and elongation than the cross-linker. The pore size distribution of the membranes ranged from 28.1 to 51.6 Å with BET surface areas of 13.8-23.8 m 2 g −1 . Water permeation studies were conducted using a cross-flow MF module in batch analyses. The results indicated that 2:1 CSG membranes effectively removed over 95% of bacteria notably, Escherichia coli from wastewater. Various blocking mechanisms were investigated and are discussed in detail utilizing various fouling models such as standard, intermediate, complete, and cake formation, of which the cake formation model had the highest correlation coefficient of these models.

“…E. coli, among other bacterial species, is a commonly used conventional bacterial indicator for wastewater quality and standards [9]. MF treatment is one of the economical wastewater treatment processes that can eliminate such kind of bacterial species and are deemed as a preferred treatment method [10].…”

“…Klaysom et al (2011) highlighted that the rubber-filler interactions are weakened with increasing filler loadings. Based on Figure 5, the organic molecules and suspension in raw POME might be deposited on the membrane surface and inside the pores of the membrane, thus affecting the permeability rate of POME (Madaeni et al 2013). The average of pore size and the thickness measurement by cross section of the membrane are tabulated in Table 1.…”

“…The higher permeability of POME was achieved up to 3.44 Lm -2 h -1 at 8 bar which took a longer period of time to filter due to high contents of organic matter and suspended solid in POME. Madaeni et al (2013) stated that the material deposited on the membrane surface or within the membrane pores controls the flux. Based on the graph, it can be concluded that the membrane was still not in fouling state due to the increase of POME permeability within 6 h of filtration.…”

Epoxidized natural rubber/polyvinyl chloride/microcrystalline cellulose (ENR/PVC/MCC) composite membranes were prepared and used to treat palm oil mill effluent (POME). The loadings of MCC were varied at 0, 5, 10 and 15 w/w%. The increment of MCC loads has intensified the hydroxyl peak of the membranes in FTIR spectrum, indicating the increase in membrane hydrophilicity. MCC acted as a pore forming agent since the ENR/PVC/10% MCC gave the highest water flux and well-distributed pores. After first treatment of POME, the levels of chemical oxygen demand (COD), biochemical oxygen demand (BOD) and total suspended solid (TSS) were reduced to 99.9%, 70.3%, and 16.9%, respectively. These data showed that ENR/PVC/MCC membrane has the potential to treat POME.

“…Furthermore, membrane 53 filtration processes offer relatively simple operation conditions in comparison to 54 conventional methods such as slow sand filtration [14], filtration/disinfection [15] and 55 flocculation/chlorination [16]. 56 In a portable water purification kit, such as point-of-use water treatment (PoUWT) 57 technology, several interdependent and coupled processes take place, such as, 58 various types of interactions between particles, water and membrane materials. It is 59 therefore important for designing of these systems to understand these processes as 60 well as quantify them for a specific case.…”

During emergency situations, effective and quick reactions are vital in order to supply 7 safe and unpolluted drinking water within approved guidelines Point-of-use water 8 treatment (PoUWT) system, for instance, portable membrane-based water treatment 9 devices, could help affected people to survive while waiting for aids to arrive. In the 10 context of portable membrane-based water purification devices, it is also found that 11 the most literature does not mention particle depositions and interactions, and 12 membrane fouling mechanisms that might occur in these devices.
