ClearInvestigating 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.
Differences 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.
Differences 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 produced by two treatment plants using different technologies, finding that treatment design significantly affected which and how many microplastics remained in finished water. The results highlight the importance of treatment technology in determining consumer exposure to microplastics in tap 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.
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.
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.
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.
Assessment of microplastic contamination in drinking water from an italian plant: An analytical study
Researchers analyzed microplastic contamination at multiple treatment stages in a drinking water plant in northern Italy that processes turbid river water supplemented with groundwater, quantifying particles through sedimentation, flocculation, sand filtration, activated carbon adsorption, and disinfection stages.
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.
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.
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 Efficiency of Microplastics in Four Drinking Water Treatment Plants in Zhengzhou, China
Researchers sampled four drinking water treatment plants in Zhengzhou, China, and found microplastics in raw water (13–25 particles per litre) with only partial removal — fibers and fragments dominated, and the treatment process actually shifted polymer composition, with PET becoming the most prevalent type in finished drinking water. The study is significant because it demonstrates that standard treatment cannot fully eliminate microplastics from tap water, meaning that people are regularly consuming microplastics from treated municipal supplies.
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.
