ClearMethod development for microplastic analysis in wastewater
This book chapter describes methods developed to detect and measure microplastics in wastewater samples, addressing the lack of standardized analytical protocols. Reliable detection methods are essential because wastewater treatment plants are a major pathway through which land-based microplastics enter aquatic environments.
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.
Evaluation of the Presence of Microplastics in Wastewater Treatment Plants: Development and Verification of Strategies for Their Quantification and Removal in Aqueous Streams
Researchers evaluated microplastic presence in wastewater treatment plants and developed a pilot capture system capable of detecting, quantifying, and removing microplastic particles from water. The study found that conventional treatment processes are insufficient for complete microplastic removal, highlighting the need for dedicated technologies to address this gap in water treatment infrastructure.
A multidimensional study of wastewater treatment
This review covers the full range of wastewater treatment approaches, from physical and chemical methods to biological and membrane-based technologies. The paper summarizes how different contaminant types — including microplastics — are handled by various treatment systems. It serves as a broad reference for understanding current wastewater management capabilities and limitations.
Validation of Sample Preparation Methods for Microplastic Analysis in Wastewater Matrices—Reproducibility and Standardization
Sample preparation methods for microplastic analysis in wastewater were validated against reference standards to assess recovery rates and reproducibility.

A Critical Review of Extraction and Identification Methods of Microplastics in Wastewater and Drinking Water
This critical review of methods for detecting microplastics in wastewater and drinking water identifies major inconsistencies in sample collection, processing, and characterization across studies, making it difficult to compare reported concentrations. A five-criteria ranking system is proposed to evaluate the quality and completeness of microplastics studies.
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.
The Effect of Wastewater Treatment Plants on Retainment of Plastic Microparticles to Enhance Water Quality—A Review
This review examined how well wastewater treatment plants remove microplastics, finding that most conventional systems achieve high removal rates but still discharge significant plastic quantities in treated effluent and sludge. Improving treatment efficiency and preventing sludge application to farmland are key strategies for reducing microplastic release.
Selection of a sustainable treatment process for removal of microplastics from wastewater by axiomatic design and PROMETHEE
Researchers compared multiple water treatment processes for microplastic removal and identified selection criteria for sustainable treatment approaches, finding that coagulation-flocculation, membrane filtration, and biological treatment each offered different trade-offs in cost, efficiency, and byproduct generation.
Wastewater treatment plants as a pathway for microplastics: Development of a new approach to sample wastewater-based microplastics
Researchers developed a new sampling and monitoring protocol for microplastics at wastewater treatment plants, enabling more consistent tracking of microplastic loads through treatment stages and discharged effluent.
Microplastic 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 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.

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.
