Applications of Membrane Bioreactors for Wastewater Treatment: MPs Removal, Mechanisms and Future Perspectives
AI summary Read the abstract
Researchers reviewed how membrane bioreactor technology can remove microplastics from wastewater far more effectively than conventional treatment plants, potentially preventing millions of plastic particles per day from being discharged into rivers and oceans.
The presence of microplastics (MPs) in wastewater has significant impacts on various aspects of the wastewater treatment process. Traditional treatment plants are not equipped to remove MPs, resulting in daily discharge into the environment. Membrane bioreactor (MBR)...

Removal of Microplastic from Wastewater Treatment Plants
AI summary Read the abstract
This review evaluated stage-by-stage microplastic removal efficiencies across wastewater treatment plant unit processes — including screening, sedimentation, biological treatment, and tertiary filtration — and assessed emerging innovations such as membrane bioreactors and advanced oxidation to improve removal rates beyond current averages of 70–99%. Because treated wastewater effluent is a primary pathway for microplastics to reach rivers and drinking water sources, optimizing removal at these facilities is one of the highest-leverage interventions available for protecting human health.
Possibilities of removing microplastics from the aquatic environment using membrane processes
AI summary Read the abstract
Tiny plastic particles are showing up in our drinking water, and this review paper looks at how well water treatment plants can filter them out. The good news: special membrane filtering systems (especially ones that combine filtering with bacteria that break down waste) can remove up to 99.9% of microplastics from wastewater, though scientists still need to solve some practical challenges before these systems can be widely used everywhere. This matters because reducing microplastics in our water supply could help limit our exposure to these particles, whose long-term health effects are still being studied.
Principles and Methods for the Removal of Microplastics in Wastewater
AI summary Read the abstract
Researchers reviewed the principles and methods used to remove microplastics from wastewater, evaluating the effectiveness of treatment approaches across domestic, industrial, and environmental discharge scenarios. Because wastewater treatment plants are a key pathway for microplastics entering aquatic environments, improving removal efficiencies is critical to reducing the downstream human and ecological exposure burden.
