ClearMicroplastics in municipal wastewater treatment plants in Turkey: a comparison of the influent and secondary effluent concentrations
Microplastics were detected in both influent and secondary effluent at two wastewater treatment plants in Turkey, with fibers as the predominant type in both streams. The study confirms that Turkish wastewater systems discharge substantial numbers of microplastic particles into receiving waters, consistent with findings from other countries.
Occurrence, Characteristics, and Removal of Microplastics in Wastewater Treatment Plants
This review summarizes the occurrence, characteristics, and removal efficiency of microplastics in wastewater treatment plants, highlighting how these facilities simultaneously act as sinks trapping microplastics and as sources releasing them into surrounding aquatic and terrestrial environments.
Evaluation of microplastics removal efficiency at a wastewater treatment plant discharging to the Sea of Marmara
Researchers tracked microplastics through all compartments of a secondary wastewater treatment plant in Istanbul, finding that the plant removed about 86% of incoming microplastics but still discharged a substantial number to the Sea of Marmara, with fibers as the dominant form.
Presence of Microplastic in Erzurum Urban Wastewater Treatment Plant
Researchers investigated microplastic presence at the inlet and outlet of the Erzurum Urban Wastewater Treatment Plant in Turkey, finding average concentrations of 36,400 MP/m3 in influent and 2,875 MP/m3 in effluent. Tertiary treatment achieved over 90% removal efficiency, while primary and secondary treatment alone proved insufficient for effective microplastic removal.
The fate of microplastics in wastewater treatment plants: An overview of source and remediation technologies
This review examines how wastewater treatment plants serve as key pathways for microplastic entry into the environment, analyzing removal efficiencies across different treatment stages and identifying advanced technologies for improved microplastic remediation.
Abundance and characteristics of microplastics in an urban wastewater treatment plant in Turkey
A wastewater treatment plant in Bursa, Turkey removed 93.7% of incoming microplastics from wastewater, with the average influent concentration of 135 MPs per liter reduced to 8.5 MPs per liter in the effluent. Despite high removal efficiency, the plant still released an estimated 525 million MPs per day to receiving waters due to the large volume of treated wastewater.
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.
Occurrence and Removal of Microplastics in Wastewater Treatment Plants: Perspectives on Shape, Type, and Density
Researchers compiled data from multiple countries on microplastic removal efficiency across different stages of wastewater treatment plants. They found that removal rates varied widely, from 48% in some facilities to over 90% in others, depending on the treatment technologies employed. The study suggests that while conventional wastewater treatment can capture a significant portion of microplastics, advanced tertiary treatment methods are needed to further reduce discharge into the environment.
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 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.
Microplastic emission trends in Turkish primary and secondary municipal wastewater treatment plant effluents discharged into the Sea of Marmara and Black Sea
Researchers tracked microplastic emission trends from Turkish primary and secondary municipal wastewater treatment plant effluents, finding that while treatment reduces MP concentrations, significant quantities are still discharged into receiving water bodies.
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.
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.
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.

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.
Efficiency of Wastewater Treatment Plants (WWTPs) for Microplastic Removal: A Systematic Review
