“…Adsorption of appropriate hydrophilic polymers on the membrane surface can contribute to repulsion between the protein molecule and membrane surface . Increasing the hydrophilicity of the membrane surface by blending with hydrophilic polymers, , coating, , and surface grafting , can effectively reduce irreversible membrane fouling. These strategies provide hydrophilic polymers to the membrane matrix directly or indirectly, enhancing the antifouling capabilities of the polymer membrane …”

“…Direct mixing of additive macromolecules with the host membrane matrix to introduce their properties into the membrane polymer is one blending strategy. Some additives used in the blending technique are polyvinylpyrrolidone, , polyethylene glycol, , polyvinyl alcohol, , polyacrylic acid, , poly(sodium 4-styrenesulfonate), polyethyleneimine, , Pluronics, and chitosan. , Kumar et al found that chitosan can improve membrane performance. Chitosan solution can be used as a surface coating for non-woven fabric membranes to improve their antifouling qualities and inhibit protein degradation in UF membranes via immersion or flow-through methods.…”

The combination of chitosan and metal oxides was utilized as an addition to improve the fouling resistance of polyethersulfone (PES) ultrafiltration membranes. Pure water flux, membrane hydrophilicity by the contact angle, scanning electron micrographs, and Fourier-transform infrared spectra were used to characterize the membranes. With the addition of metal oxides, the modified membrane’s water flux increased. The PES membrane with 0.25% wt chitosan and 2.0% wt AgNO3 had the highest flux and antibacterial activity among the membranes tested. Because of its potential to improve membrane hydrophilicity, the water flux increased with the addition of chitosan and AgNO3. Because of the improved hydrophilicity, the contact angle reduced as chitosan and Ag loading was increased. The PES–chitosan–Ag2O (from AgNO3 2.0% wt) membrane had high antibacterial activity against Escherichia coli and Staphylococcus aureus, whereas the PES–2.0% wt Ag membrane did not show the same result. Finally, the addition of chitosan in the PES–Ag membrane increased the membrane’s antibacterial activity substantially.
