ClearMicroplastics in wastewater treatment plants: Sources, properties, removal efficiency, removal mechanisms, and interactions with pollutants
This review examines microplastic sources, properties, removal efficiency, and removal mechanisms across different wastewater treatment plant stages. Researchers found that while treatment plants remove a significant portion of microplastics, they cannot eliminate them entirely, resulting in the continued release of millions of particles into the environment daily through effluent and sludge.
Microplastics in Wastewater Treatment Plants: Characteristics, Occurrence and Removal Technologies
This review summarizes how wastewater treatment plants are a major pathway for microplastics entering the environment, covering the types, sizes, and sources of microplastics found in wastewater. While treatment plants can remove many microplastics, significant amounts still escape into rivers and oceans through treated water and sludge. The authors evaluate various removal technologies and recommend advanced treatment methods to better prevent microplastics from reaching water supplies.

Microplastics removal in wastewater treatment plants: a critical review
This critical review of microplastic removal in wastewater treatment plants examines removal efficiencies across different treatment stages, finding that while WWTPs remove the majority of microplastics from influent, they still release millions of particles daily and are a major pathway for microplastics entering aquatic environments.
Toward a Better Understanding of the Contribution of Wastewater Treatment Plants to Microplastic Pollution in Receiving Waterways
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.
Challenges and Fate of Microplastics in Wastewater Treatment Processes
This review examines the challenges microplastics (MPs) pose within wastewater treatment processes (WWTPs), noting that WWTPs can act as both sinks and secondary sources of MP contamination in water bodies. The authors survey various treatment approaches and their effectiveness in capturing MPs before effluent discharge.
Microplastics in wastewater plants: A review of sources, characteristics, distribution and removal technologies
This review provides a comprehensive look at how microplastics enter, move through, and are removed from wastewater treatment plants. Researchers found that while treatment processes can remove a significant portion of microplastics from water, large quantities still escape into rivers and oceans. The study highlights the need for improved treatment technologies and better monitoring to reduce microplastic discharge from these facilities.
Where do they go? A review of the wastewater treatment process and its impact on the fate of microplastics
This review examines the fate of microplastics across the physical, chemical, and biological stages of wastewater treatment plant (WWTP) processes, finding that WWTPs act as both sources and destinations for microplastics while not being designed to remove them, and surveying new removal strategies.
Microplastics in Wastewater
This review examines microplastic detection, occurrence, and removal across wastewater treatment plant stages, finding that while treatment plants are a major source of microplastic pollution, no standardized detection protocols exist and removal efficiency remains inconsistent across facilities.
Recent advances on microplastics pollution and removal from wastewater systems: A critical review
This review summarizes the latest research on microplastic detection, occurrence, and removal in wastewater treatment plants. While treatment plants can remove 57-99% of microplastics depending on the stage, significant amounts still escape into the environment through treated water and sludge. The findings highlight the need for advanced treatment methods to prevent microplastics from reaching waterways and ultimately human water supplies.
Research progress on microplastics in wastewater treatment plants: A holistic review
This review provides a holistic assessment of microplastics in wastewater treatment plants, covering sampling methods, occurrence patterns across treatment stages, removal efficiencies, and the environmental risks posed by microplastic discharge through effluent and sludge.
Microplastics and Wastewater Treatment Plants—A Review
This review examines the role of wastewater treatment plants in retaining microplastics before they enter the environment. Studies show that no wastewater treatment method achieves complete microplastic removal, making treatment plants themselves point sources of microplastic discharge into aquatic environments. The review also discusses concerns about microplastic-laden sewage sludge being applied to agricultural land.
The Effect of Wastewater Treatment Plants on Retainment of Plastic Microparticles to Enhance Water Quality—A Review
This review examined how well wastewater treatment plants remove microplastics, finding that most conventional systems achieve high removal rates but still discharge significant plastic quantities in treated effluent and sludge. Improving treatment efficiency and preventing sludge application to farmland are key strategies for reducing microplastic release.
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.
A global review of microplastics in wastewater treatment plants: Understanding their occurrence, fate and impact
A global review of 121 wastewater treatment plants found that microplastics are consistently present in both influent and effluent, with WWTPs acting as major conduits delivering plastics into aquatic and terrestrial ecosystems. While removal efficiencies varied widely, the sludge produced by these plants represents a concentrated secondary pathway for microplastic release to land.
Wastewater treatment plant effluent as a source of microplastics: review of the fate, chemical interactions and potential risks to aquatic organisms
This review examines wastewater treatment plant effluent as a source of microplastics entering aquatic environments. The study found that even though treatment plants remove most microplastics, the small amounts remaining in effluent may still contribute significantly to environmental contamination, and the chemical interactions between microplastics and other pollutants in wastewater raise additional ecological concerns.
Influence of wastewater treatment process on pollution characteristics and fate of microplastics
Researchers investigated microplastic abundance and removal efficiency across four wastewater treatment plants using different treatment technologies, finding influent concentrations between 539 and 1,290 particles per liter that were reduced substantially by primary and secondary treatment. Smaller microplastic particles proved hardest to remove and most likely to persist in final effluent.
