ClearCoagulation technologies for separation of microplastics in water: current status
This review examines how coagulation water treatment technologies can remove microplastics from water. Conventional coagulation achieves 8-98% removal efficiency while electrocoagulation achieves 8-99%, depending on conditions, offering a potentially effective approach for reducing microplastics in drinking water and wastewater.
Microplastics removal by coagulation: cutting-edge coagulants and coagulation processes
This review examines how coagulation, a water treatment process that clumps particles together for easier removal, can be used to filter microplastics from water. Researchers summarize recent advances in coagulant materials, including novel hybrid formulations, and the factors that influence their effectiveness. The study highlights coagulation as a practical and scalable approach for addressing microplastic contamination in water treatment systems.
Recent advances in microplastic removal from drinking water by coagulation: Removal mechanisms and influencing factors
A meta-analysis and random forest model found that coagulation can effectively remove microplastics from drinking water, with particle shape being the most important factor affecting removal efficiency, followed by coagulant type and dosage. Charge neutralization is the dominant mechanism for small microplastics, while adsorption bridging and sweeping work better for larger particles.
Treatment processes for microplastics and nanoplastics in waters: State-of-the-art review
This review summarized established and emerging treatment processes for removing microplastics and nanoplastics from drinking water and wastewater, evaluating coagulation, membrane filtration, advanced oxidation, and biological treatment in terms of removal efficiency and operational feasibility.
Microplastic removal by coagulation: a review of optimizing the reaction conditions and mechanisms
This review examines recent advances in using coagulation to remove microplastics from water and wastewater, analyzing how factors like coagulant type, dosage, pH, and particle shape affect removal efficiency. Researchers found that optimizing these reaction conditions is critical for maximizing microplastic removal while reducing energy costs. The study highlights significant knowledge gaps in understanding the mechanisms behind coagulation-based microplastic removal and calls for more extensive research.
Understanding and Improving Microplastic Removal during Water Treatment: Impact of Coagulation and Flocculation
Researchers systematically tested coagulation and flocculation for removing microplastics from drinking water, finding that removal efficiency depended strongly on plastic particle size and whether particles had been weathered, with smaller pristine particles being the hardest to remove.
Recent innovations in microplastics and nanoplastics removal by coagulation technique: Implementations, knowledge gaps and prospects
This review evaluates coagulation, a water treatment technique that uses chemicals to clump particles together for easier removal, as a method for eliminating microplastics and nanoplastics from water. Researchers found that coagulation can effectively remove these plastic particles, especially when combined with other treatment steps, but performance varies based on plastic size, shape, and water chemistry. The study identifies key knowledge gaps and recommends further research to optimize coagulation for real-world microplastic removal.
Microplastic removal by coagulation/flocculation: A review and bibliometric analysis
This review of existing research found that a common water treatment method called coagulation (where chemicals help clump particles together so they can be removed) works well at filtering out microplastics from drinking water and wastewater. The treatment is especially good at removing larger microplastic pieces, but struggles with the tiniest ones under 10 micrometers. This matters because microplastics are showing up everywhere in our water supply, and this research suggests we already have proven technology that could help reduce our exposure to these plastic particles.
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.
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.
Removal of microplastics via drinking water treatment: Current knowledge and future directions
This review examines what is currently known about microplastics in drinking water systems and how well existing water treatment processes remove them. Researchers found that while conventional treatment steps like coagulation and filtration do reduce microplastic levels, significant amounts can still persist through to tap water. The study calls for more research into optimizing treatment processes and developing monitoring strategies specifically targeting microplastic contamination in drinking water.
Microplastics removal from aquatic environment by coagulation: Selecting the best coagulant based on variables determined from a systematic review
This systematic review and experimental study identifies the most effective methods for removing microplastics from water using coagulation, a common water treatment technique. Researchers tested different coagulants on three types of microplastics and found that aluminum-based coagulants were most effective. These findings could help water treatment plants better remove microplastics from the water supply before it reaches our taps.
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.
Investigating the Potential of Coagulants to Improve Microplastics Removal in Wastewater and Tap Water
Researchers found that adding coagulants (FeCl3 or Al2(SO4)3) to wastewater and tap water improved microplastic removal, with aluminum sulfate achieving 43% and 62% removal efficiencies respectively, though the high concentrations required suggest that combining coagulants with organic polyelectrolytes could improve practicality.
Elimination of a Mixture of Microplastics Using Conventional and Detergent-Assisted Coagulation
Researchers tested coagulation as a method to remove microplastics from tap water, evaluating how microplastic type (PE and PVC), water pH, coagulant dose, and microplastic concentration affect removal efficiency, and finding that detergent-assisted coagulation improves performance.

This review evaluates various water and wastewater treatment technologies for their ability to remove microplastics, including filtration, coagulation, and advanced oxidation methods.

Problems, Challenges, and Removing Methods of Micro Plastics from Water
This review examines the presence of microplastics in drinking water — both tap and bottled — and the technologies available to remove them. Microplastics have been detected in drinking water worldwide, and while conventional treatment removes some particles, smaller nanoplastics largely pass through. The authors assess filtration, coagulation, and advanced treatment options for improving microplastic removal in drinking water systems.
