Microplastic removal in conventional drinking water treatment processes: Performance, mechanism, and potential risk
Researchers tested how well conventional drinking water treatment processes remove microplastic particles ranging from 10 to 90 micrometers in diameter. They found that larger particles were effectively removed by coagulation and sand filtration, but about 16% of the smallest particles passed through. The study also discovered that UV-based disinfection can fragment remaining microplastics into even smaller pieces and increase water toxicity, suggesting current treatment methods may need improvement.
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.

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.
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.
Development and evaluation of a water treatment system for the removal of microplastics in an aqueous medium.
Researchers developed and evaluated a water treatment system for removing microplastics from aqueous media, addressing the urgent environmental concern of microplastic contamination in rivers, seas, and oceans and assessing the system's effectiveness as a promising water purification technology.
Recent Developments in the Application of Ultrasonication in Pre-Treatment of Municipal Sewage Sludge
Not relevant to microplastics — this paper reviews ultrasonication as a pre-treatment method for municipal sewage sludge to improve anaerobic digestion efficiency, with no focus on plastic contamination.
Developing a Methodology for the Testing of Microplastics in Drinking Water Treatment Plants
Researchers developed a standardized methodology for testing microplastic removal efficiency at drinking water treatment plants, including sampling, analysis, and reporting protocols.

Evaluation of Potentially Toxic Elements and Microplastics in the Water Treatment Facility
Researchers evaluated potentially toxic elements and microplastics throughout a water treatment facility, finding both contaminant classes present at various treatment stages and raising concerns about the adequacy of current drinking water purification.
Microplastics in Drinking Water:Current Knowledge, Quality Assuranceand Future Directions
This review synthesizes current knowledge on microplastics in drinking water, covering their occurrence in source waters, behavior during treatment processes, and potential health implications. Researchers found that while drinking water treatment plants remove a portion of microplastics, standardized quality assurance methods are still lacking.
