ClearChitosan: A Novel Approach and Sustainable Way to Remove Contaminants and Treat Wastewater
This review examines how chitosan, a natural material derived from crustacean shells, can be used to remove pollutants including microplastics, heavy metals, and pesticides from wastewater. Chitosan's chemical structure allows it to bind and capture a wide range of contaminants, and it can be combined with other materials to improve its effectiveness. Developing affordable, biodegradable water treatment materials like chitosan could help reduce human exposure to microplastics in drinking water.

Synergistic removal of microplastic fibres: Integrating Chitosan coagulation in hybrid water pre-treatment systems
Microplastic fibers are the most common type of microplastic found entering water treatment plants, yet their elongated shape makes them especially hard to remove with conventional filters. This study investigated using chitosan — a natural, biodegradable material derived from crustacean shells — as a "green" coagulant to clump fibers together so they can be more easily removed, and also developed chemically modified versions of chitosan that work across a wider range of water conditions. The results showed that combining chitosan-based coagulation with microbubble aeration creates a synergistic pretreatment system that significantly improves microplastic fiber removal while avoiding the residual metal ions left by conventional chemical coagulants.
