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.
