Recent advances in treatment of microplastics in wastewater
This review examines current methods for removing microplastics from wastewater, including conventional treatment processes and newer advanced techniques.

This review examines advanced wastewater treatment technologies for removing microplastics from effluent, noting that treatment plants receive up to 372 billion microparticles daily and that primary and secondary treatment methods are insufficient to prevent environmental release.
Reuse of Water Contaminated by Microplastics, the Effectiveness of Filtration Processes: A Review
This review evaluates filtration technologies for removing microplastics from water, finding that while treatment plants reduce microplastic counts effectively, large discharge volumes still release substantial quantities into the environment.
Nano and microplastics occurrence in wastewater treatment plants: A comprehensive understanding of microplastics fragmentation and their removal
This review provides a comprehensive look at how nano- and microplastics move through wastewater treatment plants, from entry to discharge. Researchers examined how larger plastic particles fragment into smaller nano-sized pieces during treatment processes and evaluated which treatment stages are most effective at removing them. The study finds that while conventional treatment removes most microplastics, significant quantities of nanoplastics may still pass through into waterways.
Micro- and nanoplastics removal mechanisms in wastewater treatment plants: A review
This review examines how conventional wastewater treatment plants remove micro- and nanoplastics, and evaluates advanced technologies like membrane filtration and electrocoagulation that could improve removal rates. While existing treatment plants can capture most microplastics, they still release significant quantities into waterways through their enormous discharge volumes. The study highlights that biological treatment steps may also transform microplastics in potentially harmful ways that need further investigation.
A review of the removal of microplastics in global wastewater treatment plants: Characteristics and mechanisms
This review analyzed data from 38 wastewater treatment plants across 11 countries to understand how effectively they remove microplastics. While treatment plants can remove the majority of microplastics from wastewater, significant quantities still pass through into waterways, and the microplastics captured in sewage sludge may re-enter the environment when that sludge is applied to farmland.
Removal of microplastics from wastewater: available techniques and way forward
This review surveys the available techniques for removing microplastics from wastewater, including filtration, coagulation, biological treatment, and advanced methods like membrane bioreactors. Researchers found that while conventional treatment plants can remove a substantial fraction of microplastics, significant amounts still pass through to the environment. The study emphasizes the need for upgrading wastewater treatment systems to better capture these emerging contaminants.
Removal of microplastics in unit processes used in water and wastewater treatment: a review
This review evaluates various water and wastewater treatment technologies for their ability to remove microplastics, including filtration, coagulation, and advanced oxidation methods. The authors found that while conventional treatment plants can remove a large percentage of microplastics, significant quantities still pass through into treated water. The study calls for combining multiple treatment steps and developing new technologies specifically designed to capture micro- and nanoplastic particles.
Efficiency of Wastewater Treatment Plants (WWTPs) for Microplastic Removal: A Systematic Review
This systematic review examines how well wastewater treatment plants remove microplastics before releasing water back into the environment. The findings show that while treatment plants catch many microplastics, significant amounts still pass through, meaning microplastics continue to enter rivers, lakes, and oceans that supply our drinking water and seafood.
A systematic review on the occurrence and removal of microplastics during municipal wastewater treatment plants
This systematic review analyzed 54 wastewater treatment plants across 25 studies to determine how effectively they remove microplastics. The findings show an average removal rate of about 88%, but the remaining 12% passes through into waterways. This matters because the microplastics that escape treatment plants end up in rivers, lakes, and oceans, eventually entering our drinking water and food supply.
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.

Sources, fate, effects, and analysis of microplastic in wastewater treatment plants: A review
This review examines how wastewater treatment plants handle microplastics, finding that while they can remove over 90% of particles, the sheer volume of water processed means billions of microplastics still escape into waterways daily. The remaining microplastics also concentrate in sewage sludge, which is often spread on agricultural land. Wastewater treatment plants are both a filter for and a redistribution point of microplastic pollution.

This review examines how wastewater treatment plants (WWTPs) contribute to microplastic pollution in receiving waterways, synthesizing evidence on removal efficiencies of different treatment stages and the characteristics of microplastics that escape into the environment. Researchers found that while WWTPs remove the majority of incoming microplastics, they remain a significant source of microplastic discharge due to the large volumes of wastewater processed daily.
Nationwide evaluation of microplastic properties in municipal wastewater treatment plants in South Korea
Researchers evaluated microplastic levels at 22 municipal wastewater treatment plants across South Korea and found that while the plants remove over 99% of microplastics, the sheer volume of treated water still releases significant quantities into receiving waterways. Most removal happened during the sedimentation stage, and the most common microplastic types found were fragments and fibers under 300 micrometers. The study suggests that despite high removal efficiency, wastewater treatment plants remain an important source of microplastic discharge into the environment.
