Membrane-based filtration is one of the more promising technologies being explored for removing nanoplastics from drinking water, making advances in membrane design directly relevant to microplastic removal.
Microplastic in desalinated and seawater: Comparative assessment
Researchers compared microplastic concentrations in desalinated water and seawater in the Canary Islands, where desalination supplies a significant portion of the drinking water. Microplastics were detected in both source seawater and desalinated water, with desalination providing partial but incomplete removal.
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.

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.
Release of microplastics from polymeric ultrafiltration membrane system for drinking water treatment under different operating conditions
Researchers discovered that the plastic membrane filters used to purify drinking water can actually release microplastics into the treated water. The particles came not just from the membrane itself but also from plastic equipment in the system, meaning that water treatment technology designed to remove contaminants may inadvertently be adding new plastic particles to our drinking water.

Researchers examined microplastic removal by a full-scale drinking water treatment plant, finding that conventional coagulation-flocculation-filtration processes and biological filters with granular activated carbon effectively reduced microplastic concentrations in treated water.
Microplastic removal across ten drinking water treatment facilities and distribution systems
Researchers characterized microplastic removal across ten drinking water treatment facilities and found that conventional municipal treatment achieved greater than 97.5% removal, primarily through granular media filtration or ultrafiltration. Untreated source waters contained between approximately 1,200 and 7,200 microplastic particles per liter, with polypropylene, polyethylene, and polyamide being the most common types. The findings provide valuable data on microplastic exposure through drinking water and the effectiveness of existing treatment processes.
Fate and Behavior of Microplastics in Ultrafiltration Membrane Systems for Water Treatment: Fouling, Releasing, and Organic Leaching
Researchers investigated the fate and behavior of microplastics in ultrafiltration membrane systems used for water treatment, examining three key phenomena: membrane fouling caused by microplastic deposition, release of microplastics through membrane failure or bypass, and leaching of organic additives from microplastics. The work provides mechanistic understanding of how microplastics interact with ultrafiltration systems in drinking water treatment contexts.
