Synergistic removal of microplastic fibres using hybrid pre-treatment: evaluation of Chitosan as a green coagulant
Summary
Researchers evaluated the capacity of existing water treatment pre-treatment methods to remove microplastic fibers and investigated chitosan — a low-molecular-weight, 75-85% deacetylated green coagulant — as an alternative to conventional chemical coagulants. The study assessed a hybrid pre-treatment approach, finding synergistic microplastic fiber removal efficiency when chitosan was combined with existing processes.
Microplastic fibres (MPFs) are the most dominant type of microplastics detected in water and wastewater treatment plant influents.The key objectives of this research are to investigate the capacity of existing pre-treatment methods in water treatment to remove MPFs and investigate the potential of a green coagulant; Chitosan (Low molecular weight, Deacetylation 75 - 85%) on the MPF removal efficiency.

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.
Integrated Chitosan-based coagulation and microbubble pre-treatment for improved microplastic fibre removal from water
Researchers developed a combined chitosan-based coagulation and microbubble pre-treatment system for removing microplastic fibres from water, finding that this approach overcame the limitations of conventional inorganic coagulants and improved removal efficiency for the morphologically challenging fibre fraction.
Coagulative removal of microplastics from aqueous matrices: Recent progresses and future perspectives
This review examines how coagulation, a common water treatment technique, can be used to remove microplastics from water. Researchers compared the effectiveness of different coagulants, finding that natural options like chitosan and protein-based coagulants achieved removal rates above 90 percent. The study highlights the promise of natural coagulants as a more sustainable approach to tackling microplastic contamination in water treatment systems.
Enhanced removal of microplastic fibres using aluminium and chitosan-based coagulants assisted with microbubble technology
Researchers tested the removal of microplastic fibers from water using aluminium-based and chitosan-based coagulants combined with sedimentation and microbubble flotation techniques. The aluminium coagulant achieved the highest removal rate of 88% through sedimentation in humic acid-containing water, while chitosan achieved 78% removal using microbubble flotation at a lower dosage. The findings suggest that the natural coagulant chitosan has potential as an effective and greener alternative for microplastic fiber removal in water treatment.
Optimisation of Chitosan as A Natural Flocculant for Microplastic Remediation
Laboratory tests found that chitosan — a natural, biodegradable material derived from shellfish — can remove 68.3% of microplastics from water using a coagulation-flocculation process, with an optimal concentration of 30 ppm. Higher chitosan doses increased organic matter in the water (COD and BOD), suggesting a trade-off between microplastic removal efficiency and water quality parameters. Chitosan offers a promising eco-friendly alternative to synthetic chemicals for treating microplastic-contaminated water.
