Analysis of membrane surface after the filtration of surface water containing microplastic
Researchers tested ultrafiltration and nanofiltration membranes on real river water containing microplastics and found both membrane types completely removed plastic particles from the filtered water, though the deposited microplastics reduced water flow through the membranes over time — confirming membrane filtration as an effective but imperfect water treatment strategy.
A review of microplastic removal from water and wastewater by membrane technologies
This review examines how membrane filtration technologies can remove microplastics from drinking water and wastewater. Researchers found that advanced membranes like nanofiltration, reverse osmosis, and membrane bioreactors are among the most effective methods for capturing microplastic particles that conventional treatment plants miss. The study compares membrane approaches with other removal methods and discusses the challenges of membrane fouling caused by microplastic accumulation.
Membrane Distillation and Other Membrane-Related Applications for Water Cleaning and Desalination
Despite its title referencing membrane distillation for water cleaning, this paper is an editorial or introductory overview of membrane-based water treatment technologies — not a study of microplastic pollution. It broadly addresses global water scarcity challenges and is not directly relevant to microplastics research or human health.
New pilot scale concepts for water treatment with membrane technology
Researchers developed three pilot-scale water treatment concepts based on membrane technology: microfiltration/ultrafiltration for stormwater collection and purification, direct membrane filtration for wastewater treatment, and a combined forward osmosis, membrane distillation, and nanofiltration system for advanced water recovery. The pilot testing assessed the performance and practical feasibility of each approach for addressing global water scarcity.
