Filtration Solutions for Microplastic Mitigation: Cutting-Edge Filtration Technologies and Membrane Innovations for Environmental Protection
AI summary Read the abstract
This review focused on membrane-based filtration technologies—including microfiltration, ultrafiltration, and nanofiltration—as strategies for removing microplastics from water. The authors evaluated removal efficiencies across membrane types and concluded that while membranes show strong performance, fouling and operational costs remain barriers to large-scale deployment.
Microplastics represent a pressing global environmental concern due to their persistence, widespread occurrence, and adverse impacts on aquatic ecosystems and human health. Effective removal of these contaminants from water is essential to safeguard biodiversity and ensure water quality. This work focuses on the pivotal role of membrane-based filtration technologies, including microfiltration, ultrafiltration, nanofiltration, reverse osmosis, membrane bioreactors, and dynamic membranes, in capturing and eliminating microplastics. The performance of these systems depends on key membrane characteristics such as pore size, material composition, hydrophilicity, mechanical strength, and module design, which govern retention efficiency, fouling resistance, and operational stability. Membrane filtration offers a highly effective, scalable, and sustainable approach to microplastic removal, outperforming conventional treatment methods by selectively targeting a wide range of particle sizes and morphologies. By highlighting the critical contribution of membranes and filtration processes, this study underscores their potential in mitigating microplastic pollution and advancing sustainable water treatment practices.

Remediation of Micro- and Nanoplastics by Membrane Technologies
AI summary Read the abstract
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.

AI summary Read the abstract
Tiny plastic particles called microplastics are slipping through our wastewater treatment plants and ending up back in the environment—and potentially in our food and water—because standard filtering methods aren't fine enough to catch them. This review paper rounds up the latest research on advanced filter membranes that can trap these particles more effectively, while also tackling a key problem: the membranes tend to get clogged by the plastics they're filtering out. While these technologies aren't yet perfected or widely deployed, they represent a promising step toward cleaner water and reduced human exposure to microplastics, which have been linked to potential health concerns.
