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.
Unaccounted Microplastics in the Outlet of Wastewater Treatment Plants—Challenges and Opportunities
This review examines the challenges wastewater treatment plants face in capturing and detecting microplastics, highlighting significant gaps in removal efficiency and calling for improved monitoring and treatment technologies to prevent microplastic discharge into natural water systems.

Innovative technologies for removal of micro plastic: A review of recent advances
Researchers reviewed emerging technologies for removing microplastics from wastewater, covering filtration, coagulation, biological treatment, and other methods used at treatment plants. The review highlights which approaches show the most promise and calls for broader adoption and improved standardization so that microplastics are more consistently captured before they reach rivers, lakes, and oceans.
Navigating microplastics in wastewater treatment: Understanding analysis, mitigation, removal strategies, impact, and current knowledge gaps
Researchers reviewed how wastewater treatment plants (WWTPs) handle microplastic pollution, finding that while WWTPs significantly reduce microplastic levels, they still release hundreds of particles per liter into the environment daily, and inconsistent testing methods make it hard to compare results across studies.
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.
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 in treatment of microplastics in wastewater
This review examines current methods for removing microplastics from wastewater, including conventional treatment processes and newer advanced techniques. Researchers found that while standard treatment plants can remove a significant portion of microplastics, many particles still pass through into waterways, and the captured plastics often end up concentrated in sewage sludge. The study highlights the need for improved treatment technologies to more effectively address microplastic contamination in water systems.
Microplastic pollution is widely detected in US municipal wastewater treatment plant effluent
Researchers conducted a wide survey of US municipal wastewater treatment plants and found microplastics widely present in effluent, confirming that conventional treatment does not fully remove microplastics and that treatment plants are ongoing sources of environmental contamination.
Advancements and Regulatory Situation in Microplastics Removal from Wastewater and Drinking Water: A Comprehensive Review
This review examines current methods for detecting and removing microplastics from wastewater and drinking water treatment plants. Researchers found that while existing treatment processes remove many microplastics, some particles still pass through to discharge into natural water bodies. The study also provides an overview of regulations and policies in the United States addressing microplastic contamination in water systems.
Microplastics removal through water treatment plants: Its feasibility, efficiency, future prospects and enhancement by proper waste management
Researchers reviewed over 80 studies on water treatment plant performance and found microplastic removal ranges widely — from 16% in basic primary treatment up to near 100% with advanced membrane systems — but a major flaw is that removed microplastics concentrate in sludge, which can re-enter the environment. The review recommends optimizing coagulants and sludge treatment to prevent microplastics from simply being relocated rather than eliminated.

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.

Size- and Polymer-Specific Assessment of Micro- and Nanoplastics in a European Wastewater Treatment System
Scientists studied tiny plastic particles in European wastewater treatment plants and found that these facilities can remove most microplastics from sewage, but many still escape into the environment. Even though the treatment plants filter out a lot of plastic pollution, the enormous amount of wastewater they process means millions of plastic particles still end up in rivers and oceans every day. This matters because these plastic particles can eventually make their way into our drinking water and food chain, potentially affecting human health.
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.
