“…Self‐assembly of natural polysaccharides has proved to be a good method for the preparation of gylcosylated membranes. Through this method, Yu et al has prepared glycosylated poly( l ‐lactic acid), poly(tetramethylene adipate‐ co ‐terephthalate), and polysulfone (PSF) membranes with these natural charged polysaccharides, respectively.…”

Development in the area of glycosylated membranes has been actively pursued in the past few years. This kind of promising biomimetic material is inspired by cell membranes. The recent surge of interest in these glycosylated membranes stems from their widespread number of applications to many areas in science and technology. With the glycosylation strategy, membrane separation properties, such as flux and antifouling, are greatly improved. Moreover, the ability to modulate biocompatibility, protein recognition, separation of biomolecules, enzyme immobilization, cell culture, and microorganisms capture are important in a variety of biological and medical applications. This review focuses on the recent progress in the preparation of these glycosylated membranes and highlights their applications.

“…Chitosan has been employed for adsorption of metal ion, pesticides, endocrine disruptors, drugs, tincture agents, dyes and pigments (Krajewska 2005). Chitosan is also found to be non-toxic and biodegradable (Boributh et al 2009;Hamzah et al 2012). The eco-friendly biopolymer sorbent possesses improved phase separation and acts as very useful and excellent material for treating wastewater (Le Roux et al 2005).…”

Purification of water is a critical and inevitable process at present to avoid the harmful effect of polluted water and to meet the need for safe drinking water to millions of people in the world. Several methods of water purification exist, but the combination of adsorption and filtration is found to be paramount in the water treatment process owing to the cost-effectiveness and efficacy of the process. The submerged ceramic membrane bioreactor, which includes both bioreactor and filtration system, is one of the most promising technologies effectively employed for water purification. The main hardship in using the membrane bioreactor system is the phenomena called fouling which decreases and gradually ceases the separation capacity of the membrane. The present work focuses on the reduction of fouling, thus increasing the efficacy of the membrane bioreactor system. The two green composite materials, chitosan beads with activated carbon (CH-AC) and cellulose acetate flakes with activated carbon (CA-AC), were used for the first time for reduction of fouling and found to be an excellent aid in the reduction of fouling. The composites synthesized were subjected to characterization using SEM, TEM and BET to study the physical properties of the composites. The optimum dosage of CH-AC and CA-AC for effective reduction of fouling was analysed. Thus, the present work imparts the novel, efficient, economical and eco-friendly solution for fouling reduction and also a significant improvement in the quality of effluent water.

This work focuses on utilizing the dual role of sulfonated polyphenyl sulfone (SPPSU) as both an anchoring agent and an interlayer modifying agent in the preparation of nano MgO/SPPSU/PPSU membranes for oil removal from water. These asymmetric membranes were prepared using the phase inversion technique. The dispersed nano MgO was observed in the membrane matrix as seen by scanning electron microscope and energy dispersive X-ray analysis. The reduction in contact angle value establishes the increases in hydrophilicity. An increase in SPPSU (wt %) loosens the nano MgO/SPPSU/PPSU membrane packing as exhibited by the increase of d-spacing by X-ray diffraction analysis. The antifouling properties were tested using humic acid, as a model foulant. Further, in castor oil/water emulsion separation, it was found that the membrane with 25 wt % anchored moiety SPPSU/nano MgO produced a greater flux recovery ratio of 94.9% (60.3) without compromising the oil rejection of 99% (60.4) and better oleophobic surfaces for oil.
