“…A mixed matrix membrane (MMM) based on cellulose acetate was created using the phase inversion approach, together with the use of mixed metal oxide nanoparticles as nanofillers. The results of the tests indicated that the MMM was less susceptible to attack by microbes, and it was discovered that the fluoride ion was rejected due to adsorption, while the membrane surface exhibited electrostatic repulsion, enhancing the defluorination effectiveness [30]. The MWNT was disseminated in an aqueous solution containing varying quantities of chitosan, and the membrane was formed.…”

Due to the versatility of its features and capabilities, chitosan generated from marine crustacean waste is gaining importance and appeal in a wide variety of applications. It was initially used in pharmaceutical and medical applications due to its antibacterial, biocompatible, and biodegradable properties. However, as the demand for innovative materials with environmentally benign properties has increased, the application range of chitosan has expanded, and it is now used in a variety of everyday applications. The most exciting aspect of the chitosan is its bactericidal properties against pathogens, which are prevalent in contaminated water and cause a variety of human ailments. Apart from antimicrobial and water filtration applications, chitosan is used in dentistry, in water filtration membranes to remove metal ions and some heavy metals from industrial effluents, in microbial fuel cell membranes, and in agriculture to maintain moisture in fruits and leaves. It is also used in skin care products and cosmetics as a moisturizer, in conjunction with fertilizer to boost plant immunity, and as a bi-adhesive for bonding woods and metals. As it has the capacity to increase the life span of food items and raw meat, it is an unavoidable component in food packing and preservation. The numerous applications of chitosan are reviewed in this brief study, as well as the approaches used to incorporate chitosan alongside traditional materials and its effect on the outputs.

“…The incorporation of nanofillers into a polymer matrix is one of the most efficient methods to enhance the properties of a polymer; through this, an improved performance and surface modification of polymer materials are achievable. Examples of such nanofillers are organic, inorganic, metal, and metal oxide nanoparticles [ 123 , 124 , 125 ]. Cellulose nanocrystals (CNCs) are renewable, degradable, and made from renewable natural cellulose.…”

The improvement of membrane applications for wastewater treatment has been a focal point of research in recent times, with a wide variety of efforts being made to enhance the performance, integrity and environmental friendliness of the existing membrane materials. Cellulose nanocrystals (CNCs) are sustainable nanomaterials derived from microorganisms and plants with promising potential in wastewater treatment. Cellulose nanomaterials offer a satisfactory alternative to other environmentally harmful nanomaterials. However, only a few review articles on this important field are available in the open literature, especially in membrane applications for wastewater treatment. This review briefly highlights the circular economy of waste lignocellulosic biomass and the isolation of CNCs from waste lignocellulosic biomass for membrane applications. The surface chemical functionalization technique for the preparation of CNC-based materials with the desired functional groups and properties is outlined. Recent uses of CNC-based materials in membrane applications for wastewater treatment are presented. In addition, the assessment of the environmental impacts of CNCs, cellulose extraction, the production techniques of cellulose products, cellulose product utilization, and their end-of-life disposal are briefly discussed. Furthermore, the challenges and prospects for the development of CNC from waste biomass for application in wastewater treatment are discussed extensively. Finally, this review unraveled some important perceptions on the prospects of CNC-based materials, especially in membrane applications for the treatment of wastewater.

“…A mixed matrix membrane based on cellulose acetate with the incorporation of mixed metal oxides (Fe -Al -Mn) and chitosan was fabricated by Chaudhary and Maiti [165] with the aim of removing fluoride contamination in groundwater. To achieve that, several parameters were optimized, reaching the optimum conditions of transmembrane pressure of 6 to 8 bar, pH between 6 and 9, and adsorbent mass of 8%.…”

The utilization of sustainable and high-performance technologies is a growing tendency in industrial processes. The membrane separation process is a clean technology alternative that can be used to separate, concentrate, and/or purify substances. But there is still a great interest in turning this process increasingly sustainable by the structural modification of the membranes using biopolymers and green solvents, and the functionalization with organic and inorganic materials, also improving their performance and anti-fouling characteristics. Thus, this review chapter brings the main concepts about membranes and their main structural modifications to obtain a process that meets the concepts involved in Green Technology.
