ClearMicroplastics 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.
Treatment 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.
Microplastics in aquatic systems: An in-depth review of current and potential water treatment processes
This review provides a detailed examination of microplastic contamination in aquatic systems and evaluates current and emerging water treatment technologies for their removal. Researchers assessed methods ranging from conventional coagulation and filtration to advanced techniques like membrane bioreactors and electrochemical processes. The study concludes that while no single technology fully eliminates microplastics, combining multiple treatment approaches offers the most promising path forward.
Membrane bioreactor and rapid sand filtration for the removal of microplastics in an urban wastewater treatment plant
A wastewater treatment plant was monitored for 18 months to compare microplastic removal by membrane bioreactor technology versus rapid sand filtration, finding that membrane bioreactors achieved much higher removal efficiency but that both technologies still released microplastics into receiving waters.
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.
How to remove microplastics in wastewater? A cost-effectiveness analysis
A cost-effectiveness analysis of microplastic removal in wastewater treatment found that activated sludge, rapid sand filtering, and membrane bioreactor technologies differ substantially in removal efficiency and cost per unit removed, with membrane bioreactors achieving the highest removal but at prohibitive cost.
Rapid Sand Filtration Technique for Remediation of Microplastics
Researchers tested rapid sand filtration as a technique for removing microplastics from water, evaluating particle removal efficiency across different plastic sizes, shapes, and filter media. The technique achieved meaningful microplastic reduction and was proposed as a practical water treatment enhancement.
Micro- and nanoplastics removal from water and solid matrices: Technologies, challenges, and future perspectives
Researchers reviewed a decade of research on micro- and nanoplastic removal technologies across water and solid matrices, finding that conventional water treatment achieves over 80% microplastic removal but transfers most particles to sludge rather than degrading them, while advanced oxidation processes show strong degradation potential under controlled but not yet real-world conditions.
Occurrence, identification and removal of microplastics in a wastewater treatment plant compared to an advanced MBR technology: Full-scale pilot plant
Researchers compared microplastic removal efficiency between a standard wastewater treatment plant and an advanced membrane bioreactor (MBR) system and found MBR technology achieved 99.7% removal — far outperforming conventional treatment — suggesting upgraded filtration systems are critical to keeping microplastics out of waterways.
