Researchers evaluated microplastic characteristics and removal efficiency at the Ujung Menteng Flat House Sewerage Treatment Plant in Indonesia, sampling from influent, activated sludge, and effluent to assess how effectively existing wastewater infrastructure — not designed for microplastic removal — reduces contamination.
Characterization and Removal of Microplastics in Different Stages of Wastewater Treatment Plants
This review examines the types, shapes, and sizes of microplastics found in domestic and industrial wastewaters and evaluates the removal efficiency of different treatment processes across wastewater treatment plant stages, noting that no existing process achieves 100% removal.

Researchers investigated microplastic distribution in three industrial wastewater treatment plants in Vietnam, finding average removal efficiencies of only 21-26%, with billions of microplastic particles discharged daily into receiving waters from the largest plant.
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.
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.
Evaluation of microplastic removal efficiency of wastewater-treatment plants in a developing country, Vietnam
Researchers evaluated microplastic removal efficiency at four wastewater treatment plants in Vietnam, finding removal rates of 92-99% but substantial daily microplastic loads still entering receiving waters through effluent discharge.
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.
Effects of different treatment processes in four municipal wastewater treatment plants on the transport and fate of microplastics
Researchers investigated microplastic transport and fate across four municipal wastewater treatment plants in southeastern China, finding that different treatment processes varied in their microplastic removal efficiency, with fibers and fragments as the dominant types.
Study of occurrence, abundance, and characterization of microplastics in wastewater treatment plant in New Delhi, India
Researchers quantified microplastic prevalence in influent, treated effluent, and sludge from a wastewater treatment plant in New Delhi, finding that MPs are present throughout the treatment process and that the plant incompletely removes them, discharging MPs into receiving waters.
A study on characteristics of microplastic in wastewater of South Korea: Identification, quantification, and fate of microplastics during treatment process
Microplastics were tracked through three South Korean wastewater treatment plants with different tertiary treatment methods, finding 75–92% removal by primary and secondary treatment and over 98% removal after tertiary treatment. The study confirms that advanced treatment steps are necessary to approach near-complete microplastic removal from municipal wastewater.
The fate of microplastics in wastewater treatment plants: An overview of source and remediation technologies

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.
Effectiveness of conventional municipal wastewater treatment plants in microplastics removal: Insights from multiple analytical techniques
Researchers evaluated the effectiveness of conventional municipal wastewater treatment plants in removing microplastics across multiple treatment stages, finding removal efficiencies of 70–90% but documenting that billions of particles still pass through in final effluent daily.

This review examined the capacity of wastewater treatment plants in India to remove microplastics, synthesizing current knowledge on removal efficiencies and identifying major knowledge gaps and future research priorities. While WWTPs remove a substantial fraction of incoming microplastics, effluents still discharge particles into receiving water bodies, and sludge represents a concentrated secondary contamination pathway.
