ClearWastewater Treatment Methods for Removal of Microplastics from Effluents
This book chapter reviewed pressure membrane technologies — including ultrafiltration, nanofiltration, and reverse osmosis — for removing microplastics and nanoplastics from wastewater effluents. The authors evaluate the performance, cost, and limitations of each membrane type and discuss how combinations of technologies can achieve higher removal efficiencies.
Performance of MOF-containing active layer and HOF-based support layer of ultrafiltration membrane for nanoplastics removal from secondary effluent
Researchers built a novel ultrafiltration membrane using two advanced porous framework materials to filter nanoplastics out of real wastewater treatment plant effluent, successfully identifying and removing poly(methyl methacrylate), polyethylene, and polystyrene nanoparticles. The work addresses a critical gap because conventional wastewater treatment does not reliably remove nanoplastics before treated water is discharged.
Fouling behavior heterogeneity of typical nanoplastics in widely used polyvinylidene fluoride ultrafiltration membranes
Polystyrene nanoplastics caused more severe membrane fouling and greater cleaning difficulty in polyvinylidene fluoride ultrafiltration membranes than polyethylene nanoplastics, with flux descent rates ranging from 9–36%, raising concerns about nanoplastics passing through or fouling water treatment membranes.
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.
An assessment of the impact of structure and type of microplastics on ultrafiltration technology for microplastic remediation
Researchers assessed ultrafiltration technology for microplastic removal from water, finding that membrane performance varied based on microplastic structure, size, and polymer type, with implications for optimizing tertiary treatment in water purification systems.
Advancements in Sustainable Membrane Technologies for Enhanced Remediation and Wastewater Treatment: A Comprehensive Review
This review covers membrane filtration technologies—reverse osmosis, nanofiltration, and ultrafiltration—as methods for removing contaminants from water, with relevance to microplastic and nanoplastic removal from drinking water and wastewater. Advancing membrane-based treatment is critical for reducing the microplastic load in treated water that humans and ecosystems are ultimately exposed to.
Evaluating the performance of the metal organic framework-based ultrafiltration membrane for nanoplastics removal
Researchers created an advanced membrane filter using metal-organic framework nanoparticles that removed over 99% of nanoplastics from water while maintaining high water flow rates. The membrane resisted fouling and worked reliably across multiple cycles and different water conditions. This type of technology could improve wastewater treatment plants' ability to prevent nanoplastics from reaching drinking water supplies.
Filtration Solutions for Microplastic Mitigation: Cutting-Edge Filtration Technologies and Membrane Innovations for Environmental Protection
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.
