Chitosan Nanoparticle Applications for Water/Wastewater Treatment

Author(s): Cook, C.; Gude, V.

Chitosan is an abundant naturally occurring biopolymer originating from several microbial species as well as crustacean species, such as shrimp and lobster. This biodegradable polymer has been the subject of research for water treatment applications for more than three decades due to its excellent physical and chemical properties; however, modern processes have allowed for the creation of new, novel materials. Chitosan presently offers a myriad of potential through chemical coagulation and flocculation, antimicrobial properties, adsorption capabilities, nanofiltration, and more. Such new applications as chitosan gelations, membranes, grafted nanoparticles, and other functionality-driven variations allow greater efficiency and broader implications than ever before. This presentation will discuss some of the recent developments in chitosan nanoparticle research for potential applications in water and wastewater treatment.
