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.
