Filtration Methods for Microplastic Removal in Wastewater Streams — A Review
This review surveys filtration, membrane, coagulation, and biological methods for removing microplastics from wastewater, concluding that membrane bioreactors and dynamic membranes are among the most effective current technologies.

Integrating microplastic management into a broader wastewater decision-making framework. Is activated granular sludge (AGS) a game changer?
Researchers compared three wastewater treatment technologies for their ability to remove microplastics: conventional activated sludge, membrane bioreactors, and activated granular sludge. While membrane bioreactors performed best at removing microplastics, activated granular sludge emerged as the most cost-effective option with strong overall environmental performance. The study suggests that integrating microplastic management into wastewater treatment decisions requires balancing removal efficiency against energy use, cost, and environmental impact.

This review compares wastewater treatment technologies for removing microplastics, finding that membrane bioreactors and advanced filtration systems achieve the highest removal efficiencies (>95%) but that MPs accumulating in sludge may re-enter the environment through biosolid disposal. The analysis underscores that no current treatment system completely prevents MP discharge and that sludge management is a critical but underaddressed pathway to the environment.
