ClearDifferences in the occurrence of microplastic at two technically diverse drinking water treatment plants within the same river catchment
Researchers compared microplastic occurrence in drinking water from two technically different treatment facilities, examining how treatment technology influences the presence and type of microplastics in finished drinking water. The two plants produced water with significantly different microplastic profiles, indicating that treatment technology is a key determinant of microplastic concentrations reaching consumers.
Occurrence and fate of microplastics at two different drinking water treatment plants within a river catchment
Researchers investigated the occurrence and removal of microplastics at two drinking water treatment plants located on the same river in the Czech Republic. The study found that microplastics were present in raw water at both facilities and that treatment processes reduced but did not fully eliminate microplastic contamination, with removal efficiency varying by treatment technology.
Investigating microplastics at two drinking water treatment plants within a river catchment
Researchers tracked microplastics through each treatment stage at two Czech drinking water treatment plants on the same river, finding that the downstream plant received far higher raw water concentrations (1,296 vs. 23 particles/L) and that current treatment reduced but did not eliminate microplastics from finished drinking water.
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.
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 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.
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.
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. The solution demonstrated effective removal of microplastics from drinking water under realistic treatment conditions.
Identification of microplastics in conventional drinking water treatment plants in Tehran, Iran
Researchers identified microplastics in three conventional drinking water treatment plants in Tehran, Iran, finding that standard treatment processes do not fully eliminate particles down to 1 micron in size, raising concerns about microplastic exposure through tap 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.
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.
Microplastics in drinking water treatment – Current knowledge and research needs
This review examines the current state of knowledge about microplastics in drinking water treatment, including how treatment plants remove these particles. Researchers found that conventional treatment processes like coagulation and filtration can remove a significant portion of microplastics, but some particles still pass through to finished water. The study identifies key research gaps around the effectiveness of different treatment technologies and the health implications of residual microplastics.
Properties and fate of microplastics entering drinking water treatment plants
This conference abstract reviews how microplastics behave as they pass through drinking water treatment plants, noting that while conventional treatment removes many particles, some still reach tap water consumers.

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.
