ClearMicroplastic contamination in wastewater: Sources, distribution, detection and remediation through physical and chemical-biological methods
This review covers how microplastics end up in wastewater from sources like textile fibers, personal care microbeads, and broken-down plastic debris, and how they often survive the treatment process. Current removal methods like filtration and chemical degradation are costly and not fully effective. The lack of standardized ways to measure microplastics in wastewater makes it difficult to assess the full scope of human exposure through water systems.
Detection and Characterisation Techniques for Microfiber in Wastewater
This review covers current detection and characterization techniques for microfibers, the most common type of microplastic found in the environment. Researchers discuss how microfibers are released in large quantities during home laundry and enter waterways through wastewater treatment plants. The study emphasizes that precise detection methods are essential for understanding and controlling microfiber pollution, given its harmful effects on both aquatic ecosystems and human health.
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 reviewed the fate of microfibres released from textile industry effluents, finding that conventional wastewater treatment is insufficient to fully remove fibres, which then enter receiving waterways and contribute to environmental microplastic loads.
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.
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.
Interactions between microplastics and unit processes of wastewater treatment plants: a critical review
This critical review examines how microplastics interact with each unit process in wastewater treatment plants, synthesizing removal efficiencies and identifying that while conventional treatment removes the majority of microplastics, small particles and fibers consistently pass through to effluent.
Microplastics: Occurrences, treatment methods, regulations and foreseen environmental impacts
This review provides a broad overview of microplastic pollution, covering where these particles are found, how they are treated and regulated, and what environmental impacts are anticipated. Researchers found that current wastewater treatment methods are often insufficient to fully remove microplastics, and regulatory frameworks remain inconsistent across countries. The study emphasizes the urgent need for improved treatment technologies and coordinated global policies to address this growing environmental challenge.
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.
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.
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.
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.

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.
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.
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.
Detection and removal of microplastics in wastewater: evolution and impact
This review covers methods for detecting and removing microplastics from wastewater, which is a major pathway for microplastics to enter the environment. Microplastics in water can carry heavy metals, disease-causing organisms, and chemical additives, and are eventually consumed by aquatic life that enters the human food chain. The authors emphasize that better wastewater treatment technology is needed to reduce human exposure to microplastics through water and seafood.
Wastewater Treatment Approaches to Remove Microplastics
This review summarizes current approaches for removing microplastics from wastewater, noting that treatment plants capture many particles but are not fully effective — particularly for small fibers from laundry.
