ClearAnalysis 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.
Occurrence and removal of microplastics by advanced and conventional drinking water treatment facilities
Researchers evaluated the performance of both advanced and conventional drinking water treatment processes for removing microplastics, finding that advanced methods such as ultrafiltration substantially outperform standard coagulation and filtration. Most conventional treatment plants leave a meaningful fraction of microplastics in finished drinking water.
Occurrence and removal of microplastics by advanced and conventional drinking water treatment facilities
Researchers assessed microplastic occurrence and removal efficiency at drinking water treatment plants using both conventional and advanced treatment processes. Advanced treatment steps such as ultrafiltration and activated carbon significantly improved microplastic removal compared to conventional coagulation and filtration alone.
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.
Microplastic occurrence after conventional and nanofiltration processes at drinking water treatment plants: Preliminary results
Researchers detected microplastics in source river water and finished drinking water at three treatment plants in the Paris region, finding that standard treatment steps including coagulation-flocculation and sand filtration reduced but did not eliminate MPs. Nanofiltration achieved higher removal rates, suggesting advanced filtration is needed for near-complete MP removal from drinking water.
Recent advances on micro/nanoplastic pollution and membrane fouling during water treatment: A review
Researchers reviewed recent advances in understanding how micro- and nanoplastics contribute to membrane fouling during water treatment processes. The study found that while membrane separation effectively removes microplastics from wastewater effluent, fouling caused by plastic particles along with dissolved organics and extracellular polymers remains a key obstacle, and understanding the fouling mechanisms is critical for improving treatment efficiency.
Fate of microplastics in the drinking water production
Researchers tracked the fate of microplastics through drinking water treatment processes, finding that conventional treatment steps like coagulation, sedimentation, and filtration removed the majority of microplastics but did not eliminate them entirely.
Feasibility evaluation of near dissolved organic matter microfiltration (NDOM MF) for the efficient removal of microplastics in the water treatment process
Researchers evaluated near-dissolved organic matter microfiltration as a water treatment method for removing natural organic matter precursors to disinfection by-products, testing membrane performance under varying operating conditions. Results showed that operating near the dissolved organic matter rejection threshold improved filtration efficiency while managing fouling, offering a refined approach to membrane-based water treatment.

Do membrane filtration systems in drinking water treatment plants release nano/microplastics?
Analysis of membrane filtration systems in drinking water treatment plants found that physical cleaning, chemical exposure, aging, and mechanical wear can all cause membranes to release nano/microplastics into the treated water supply — identifying treatment infrastructure itself as a potential source of plastic contamination.
Direct filtration of microfibre-containing wastewater using nanofibre membranes: combined effects of mode of filtration and type of microfibre
Scientists tested how tiny plastic fibers from clothes and textiles affect water treatment systems that remove these pollutants from wastewater. They found that different types of plastic fibers either help or hurt the cleaning process depending on the material and how the water flows through filters. This research is important because it could help improve systems that remove microplastics from our water supply before they reach rivers, oceans, and potentially our drinking water.
