ClearRemoval of microplastics and nanoplastics in water treatment processes: A systematic literature review
Researchers systematically reviewed 103 studies across 26 water treatment plants in 12 countries to assess how well various technologies remove microplastics and nanoplastics from drinking water, finding that while coagulation, filtration, and advanced treatments help, significant gaps remain. The review identifies that no single process achieves complete removal, leaving microplastics as a persistent contaminant in treated water supplies.
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.
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.
Removal of microplastics via drinking water treatment: Current knowledge and future directions
This review examines what is currently known about microplastics in drinking water systems and how well existing water treatment processes remove them. Researchers found that while conventional treatment steps like coagulation and filtration do reduce microplastic levels, significant amounts can still persist through to tap water. The study calls for more research into optimizing treatment processes and developing monitoring strategies specifically targeting microplastic contamination in drinking water.
What have we known so far about microplastics in drinking water treatment? A timely review
This review summarizes research on microplastic occurrence and removal in drinking water treatment, covering both laboratory and full-scale studies through August 2021. Researchers found that conventional treatment processes like coagulation-flocculation, membrane filtration, and sand filtration are generally effective at reducing microplastics in water, though results vary widely depending on conditions. The study identifies key factors influencing removal efficiency and highlights the need for further research on nanoplastics in 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.
Treatment technologies for the removal of micro plastics from aqueous medium
Researchers reviewed treatment technologies for removing microplastics from water, finding that while multiple methods including filtration, membrane processes, and coagulation show promise, their effectiveness depends on microplastic size, type, and concentration.
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.
Efficient removal of microplastics through a combined treatment process: Pre-filtration and adsorption
A combined treatment process integrating coagulation, sedimentation, and filtration achieved efficient removal of microplastics from drinking water. The study supports the feasibility of adapting existing water treatment infrastructure to address microplastic contamination.
Research and Trends of Filtration for Removing Microplastics in Freshwater Environments
This systematic review examines filtration methods for removing microplastics from freshwater environments. The findings show that advanced filtration technologies outperform traditional methods, offering practical solutions for reducing microplastic contamination in the water supply and lowering human exposure through 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.
A solution for controling microplastics in drinking water
Researchers developed and tested a technology for controlling microplastic contamination in drinking water, targeting particles at concentrations relevant to typical tap and bottled water exposure.

Analysis of the Efficiency of Drinking Water Treatment Systems in the Removal of Microplastics
Researchers analysed the efficiency of drinking water treatment systems in removing microplastics — primarily PET, PP, PS, and PVC fibres and fragments — from source water, reviewing how physical, chemical, and biological treatment stages contribute to reduction. The review also evaluates associated health risks including inflammation, oxidative stress, endocrine disruption, and genetic damage linked to microplastic exposure via drinking water.

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.
Problems, Challenges, and Removing Methods of Micro Plastics from Water
This review examines the presence of microplastics in drinking water — both tap and bottled — and the technologies available to remove them.
