ClearTreatment technologies for the removal of micro plastics from aqueous medium
Researchers reviewed treatment technologies for removing microplastics from water, finding that while multiple methods including filtration, membrane processes, and coagulation show promise, their effectiveness depends on microplastic size, type, and concentration.
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.

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.
Integrating microplastic management into a broader wastewater decision-making framework. Is activated granular sludge (AGS) a game changer?
Researchers compared three wastewater treatment technologies for their ability to remove microplastics: conventional activated sludge, membrane bioreactors, and activated granular sludge. While membrane bioreactors performed best at removing microplastics, activated granular sludge emerged as the most cost-effective option with strong overall environmental performance. The study suggests that integrating microplastic management into wastewater treatment decisions requires balancing removal efficiency against energy use, cost, and environmental impact.
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.

Microplastic particles in the aquatic environment: A systematic review
Among treatment technologies for microplastic removal from water, membrane bioreactors achieved the highest efficiency (>99%), followed by activated sludge (~98%) and rapid sand filtration (~97%), while hybrid treatment approaches showed the best overall removal performance.
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.
When Technology Meets Sustainability: Microplastic Removal from Industrial Wastewater, Including Impact Analysis and Life Cycle Assessment
Researchers assessed a novel pilot plant that removes microplastics from industrial wastewater using organosilane-based agglomeration followed by belt filtration, and conducted a life cycle assessment. The system achieved 98% MP removal by mass and 99.9987% by particle count while reducing chemical oxygen demand by 96%, with the life cycle assessment confirming the environmental feasibility of the approach.
Microplastic remediation technologies in water and wastewater treatment processes: Current status and future perspectives
This review covers the main technologies for removing microplastics from water and wastewater, including membrane filtration, chemical coagulation, adsorption, biological methods, and advanced oxidation. Each method has trade-offs between effectiveness, cost, and environmental impact, and no single approach removes all microplastics completely. The review emphasizes the urgent need for better removal methods since microplastics have already been detected in human blood and infant feces.
