Insight into the bionanocomposite applications on wastewater decontamination: Review

It is undeniable that water is as a scarce commodity, besides being the most overlooked nutrient for life. Nevertheless, the water situation is so challenging due to climate changes and population growth. Against this background, reducing water vulnerability is necessary by ensuring its supplies and reducing global water pollution. The blooming of nanotechnology and its expanding to a variety of sectors including water sector can have a positive impact by providing innovative solutions with enhanced efficiencies. A class of new materials currently earning growing interest in the water sector due to their countless features is the bionanocomposites (BNCs) based biopolymers. BNCs have shown efficiencies in removing organic and inorganic contaminants, as well as heavy metals and microorganisms from polluted effluents with more privileges as easier recovery from aqueous medium, better life cycles and improved treatment durations. On that account, this paper furnishes an in-depth review of bionanocomposites application in water treatment. Also, it sheds a light on the strategies for different contaminants removal, with respect to, bringing out how BNCs are convenient as highly efficient water treatment agents with reduced costs and improved efficiencies.
