ClearEradication of Microplastics in Wastewater Treatment: Overview
This review examined technologies for removing microplastics from wastewater, evaluating physical, chemical, and biological treatment methods and finding that while conventional treatment plants capture a significant fraction, emerging technologies like membrane filtration and coagulation are needed to achieve more complete removal.
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.
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.
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.
Filtration Methods for Microplastic Removal in Wastewater Streams — A Review
This review surveys filtration, membrane, coagulation, and biological methods for removing microplastics from wastewater, concluding that membrane bioreactors and dynamic membranes are among the most effective current technologies. The paper provides a useful comparative overview for engineers and policymakers seeking cost-effective solutions to prevent microplastics from passing through treatment plants into waterways.
Microplastic Removal Techniques in Domestic and Municipal Wastewater: A Systematic Review
This systematic review summarizes existing research on different methods for removing microplastics from household and city wastewater. The study found that while conventional treatment plants can remove many microplastics, advanced techniques like membrane filtration and electrocoagulation are needed to catch the smallest particles. This matters because wastewater is one of the main pathways through which microplastics enter rivers, lakes, and eventually our drinking water.
Removal of microplastics in unit processes used in water and wastewater treatment: a review
This review evaluates various water and wastewater treatment technologies for their ability to remove microplastics, including filtration, coagulation, and advanced oxidation methods. The authors found that while conventional treatment plants can remove a large percentage of microplastics, significant quantities still pass through into treated water. The study calls for combining multiple treatment steps and developing new technologies specifically designed to capture micro- and nanoplastic particles.
Recent approaches and advanced wastewater treatment technologies for mitigating emerging microplastics contamination – A critical review
This review critically assessed advanced wastewater treatment technologies for removing microplastics, noting that conventional treatment plants act as both barriers and point sources for microplastic release into the environment. The study suggests that advanced treatment approaches such as membrane filtration and advanced oxidation processes show promise for improving microplastic removal efficiency from wastewater.
Conventional and Advanced Treatment Technologies for Microplastics in Water Treatment Facilities
This review evaluated both conventional and advanced water treatment methods for removing microplastics from wastewater. Researchers found that while techniques like coagulation, filtration, and membrane bioreactors can remove most microplastics, treatment plants still release significant quantities due to the sheer volume of water processed, and microplastic-laden sludge applied to farmland creates another pathway for environmental contamination.
Removing microplastics from wastewater using leading-edge treatment technologies: a solution to microplastic pollution—a review
This review examined leading-edge treatment technologies for removing microplastics from wastewater, as treatment plants are a major pathway for microplastics entering the environment. Researchers evaluated various advanced treatment methods including membrane filtration, advanced oxidation, and electrocoagulation for their microplastic removal efficiency. The study suggests that combining multiple treatment approaches may be necessary to effectively reduce microplastic discharge from wastewater systems.
A comprehensive review of microplastics in wastewater treatment plants
This review surveys microplastic removal technologies used in wastewater treatment plants, comparing membrane bioreactors, electrocoagulation, coagulation-sedimentation, and biodegradation approaches. Understanding removal efficiency at treatment plants is critical because they are a primary pathway by which microplastics — and the toxic chemicals they carry — reach rivers, coastal waters, and ultimately drinking water supplies.
Membrane Processes for Microplastic Removal
This review evaluates the use of membrane technologies for removing microplastics and nanoplastics from wastewater treatment plant effluents. Researchers found that while membrane bioreactors show promise, most existing membrane approaches are still insufficient for comprehensive microplastic removal, especially for the smallest particles. The study suggests that specially designed membrane systems are needed as advanced tertiary treatment to prevent microplastic discharge into waterways.

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.
Removal of microplastics from wastewater for world water pool protection
This review examines existing techniques for removing microplastics from treated wastewater before it is released into natural water bodies, noting that standard treatment plants only remove 83–98% of microplastics — still leaving billions of particles entering ecosystems daily. Advanced options like membrane bioreactors and biosorbents made from agricultural waste show promise but remain costly to scale.
Technologies for the Removal of Microplastics from Wastewater: A Short Review
This review compares wastewater treatment technologies for removing microplastics, finding that membrane bioreactors and advanced filtration systems achieve the highest removal efficiencies (>95%) but that MPs accumulating in sludge may re-enter the environment through biosolid disposal. The analysis underscores that no current treatment system completely prevents MP discharge and that sludge management is a critical but underaddressed pathway to the environment.
Microplastic removal and management strategies for wastewater treatment plants
This review examines how well different wastewater treatment technologies remove microplastics and what management strategies can improve performance. While conventional treatment plants can remove a large percentage of microplastics from water, the particles often end up concentrated in sewage sludge that gets applied to farmland.
