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.
Removal of nanoplastics in water treatment processes: A review
This review examines technologies for removing nanoplastics from water, noting that conventional treatment processes effective for larger plastics often fail to capture these tiny particles. Researchers evaluated emerging methods including microbial degradation, membrane filtration, and photocatalysis, finding that combined approaches offer the best removal rates. The study highlights that more research is needed to develop practical, large-scale solutions for nanoplastic contamination in drinking water and wastewater.
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.
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. Microplastics have been detected in drinking water worldwide, and while conventional treatment removes some particles, smaller nanoplastics largely pass through. The authors assess filtration, coagulation, and advanced treatment options for improving microplastic removal in drinking water systems.
Coagulation technologies for separation of microplastics in water: current status
This review examines how coagulation water treatment technologies can remove microplastics from water. Conventional coagulation achieves 8-98% removal efficiency while electrocoagulation achieves 8-99%, depending on conditions, offering a potentially effective approach for reducing microplastics in drinking water and wastewater.
Removal efficiency of micro- and nanoplastics (180 nm–125 μm) during drinking water treatment
Researchers tested how effectively standard drinking water treatment processes remove micro- and nanoplastics ranging from 180 nanometers to 125 micrometers. They found that coagulation and sedimentation alone removed less than 2% of plastic particles, while granular filtration was far more effective, achieving 87% to nearly 100% removal depending on particle size. The study also found that biofilm formation on microplastics significantly improved their removal during coagulation treatment.
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.
Occurrence, Fate, and Treatment of Micro/Nano Plastics in Drinking Water Sources

Microplastics and nanoplastics: Recent literature studies and patents on their removal from aqueous environment
This review surveyed recent research and 42 international patents on technologies for removing microplastics and nanoplastics from water, categorizing methods into filtration, capture-based, and degradation approaches. Removal efficiencies between 58% and 100% were reported across techniques including coagulation, membrane filtration, photocatalytic degradation, and microbial breakdown. The study highlights that while promising methods exist, each has limitations depending on factors like plastic type, water chemistry, and particle size.

This review evaluates coagulation, a water treatment technique that uses chemicals to clump particles together for easier removal, as a method for eliminating microplastics and nanoplastics from water. Researchers found that coagulation can effectively remove these plastic particles, especially when combined with other treatment steps, but performance varies based on plastic size, shape, and water chemistry. The study identifies key knowledge gaps and recommends further research to optimize coagulation for real-world microplastic removal.
