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.

Technologies for the Removal of Microplastics from Wastewater: A Short Review

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.

Remediation of Micro- and Nanoplastics by Membrane Technologies

This review examined how membrane filtration technologies can remove micro- and nanoplastics from water and wastewater, since conventional treatment plants cannot fully eliminate these particles. Researchers found that techniques like ultrafiltration, nanofiltration, reverse osmosis, and membrane bioreactors are highly effective at capturing microplastics, though each has trade-offs related to cost, fouling, and energy use. The study also raises the concern that polymeric membranes themselves could potentially release plastic particles during the filtration process.
