ClearMicroplastic 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.
Effects of Microplastics on Pre-treatment Process for Seawater Desalination
Researchers examined the effects of microplastics on pre-treatment processes used in seawater desalination, investigating how microplastic contamination interferes with filtration and other preparatory steps essential to producing potable water from seawater.
Microplastics and nanoplastics contamination in raw and treated water
Researchers analyzed 189 samples of raw, tap, and bottled drinking water for micro- and nanoplastic contamination. They found plastic particles in every sample tested, with raw water sources containing the highest concentrations and treated tap water containing the lowest, though contamination was never fully eliminated. The study suggests that current water treatment processes reduce but do not completely remove plastic particles from drinking water.
Microplastics from headwaters to tap water: occurrence and removal in a drinking water treatment plant in Barcelona Metropolitan area (Catalonia, NE Spain)
Researchers tracked microplastics through an entire drinking water treatment plant in Barcelona, from river source to tap. The study found microplastic concentrations of about 1 particle per liter in the raw intake water, with sand filtration removing roughly 78% of particles and the overall treatment process achieving 93% removal. Advanced treatments like ultrafiltration and reverse osmosis proved more effective at removing microplastics than conventional ozonation and carbon filtration.

Researchers analyzed microplastic contamination in bottled water and small semi-industrial desalination stations in a water-scarce region. The study found microplastics present in both water sources, with higher levels than expected in desalination station output, raising concerns about human exposure through drinking water and highlighting the need for improved filtration standards.

Researchers explored microplastic behavior in a direct contact membrane distillation system for seawater desalination, finding that the membrane effectively removed microplastics from drinking water while certain plastic types degraded under the high operating temperatures.
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.
Contamination and Removal Efficiency of Microplastics and Synthetic Fibres in a Conventional Drinking Water Treatment Plant
Researchers found that a conventional drinking water treatment plant in Geneva removed the majority of microplastics from raw water, with coagulation and sand filtration contributing most to removal, though some particles persisted through to finished drinking water.
Identification and Quantification of Microplastics in Potable Water and Their Sources within Water Treatment Works in England and Wales
Researchers tested eight water treatment works in England and Wales and found that conventional treatment processes removed 99.99% of microplastics, reducing raw water concentrations of about 5 particles per liter to near-zero in drinking water. Polyethylene, PET, and polypropylene were the most common polymers found in the raw water supply.
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.

Researchers developed and tested a system for controlling microplastic contamination in drinking water, reporting on removal efficiency at levels relevant to public health. The approach offered effective microplastic reduction from drinking water sources including tap and bottled water.
Assessment of microplastic retention efficiency using pilot-scale filtration systems applied to drinking water
A pilot-scale study evaluated microplastic removal efficiency across a groundwater-fed drinking water treatment system in southern Spain. MPs were detected in raw groundwater and their concentrations were progressively reduced through treatment stages, though complete removal was not achieved, highlighting residual exposure risk in treated drinking water.

Mass Concentration and Removal Characteristics of Microplastics and Nanoplastics in a Drinking Water Treatment Plant
Researchers measured both microplastics and nanoplastics by mass throughout an entire drinking water treatment plant, finding that raw water contained about 9.6 micrograms per liter of plastic polymers. Treatment reduced this by roughly 92%, but nanoplastics and very small microplastics were harder to remove than larger particles. The study highlights the importance of measuring plastic contamination by mass, not just by particle count, for a more accurate picture of exposure through drinking water.
Occurrence of microplastics in raw and treated drinking water
Researchers analyzed raw and treated water from three water treatment plants and found microplastics in all samples, though treatment reduced particle counts by roughly 70 to 80 percent. The vast majority of detected particles were smaller than 10 micrometers, a size range often missed by other studies. The findings highlight that while water treatment removes most microplastics, very small particles can still pass through conventional filtration systems.
Occurrence and Source of Microplastics Contamination in Drinking Water and Performance of Water Treatment Plants in Removing Microplastics
This review summarizes evidence that microplastics are present in both tap water and bottled water worldwide, with bottled water frequently contaminated by particles shed from the plastic packaging itself. Conventional water treatment plants remove between 40% and 93% of microplastics but cannot eliminate them entirely, meaning treated drinking water still carries measurable plastic loads. The chapter highlights the irony that plastic packaging intended to deliver clean water is itself a major source of microplastic contamination.
Removal 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.
