Microplastic removal in coagulation-flocculation: Optimization through chemometric and morphological insights
Researchers optimized the coagulation-flocculation process — a standard water treatment step where chemicals cause particles to clump and settle — for removing three types of microplastics: polypropylene, polyethylene, and polystyrene.

Coagulation–Sedimentation in Water and Wastewater Treatment: Removal of Pesticides, Pharmaceuticals, PFAS, Microplastics, and Natural Organic Matter
This review evaluated how coagulation-sedimentation processes in water and wastewater treatment perform against emerging contaminants including microplastics, pharmaceuticals, pesticides, and PFAS. Researchers found that conventional coagulants can remove up to 95% of micro- and nanoplastics but are less effective for pharmaceuticals and PFAS, and that novel coagulant systems and hybrid approaches show promise for improving removal across contaminant types.
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.
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.
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.

This review examines how natural coagulants, substances derived from plants and other natural sources, can be used to remove microplastics during wastewater treatment. Natural coagulants are safer and cheaper than chemical alternatives, and show promise for capturing microplastic particles. Since wastewater treatment plants are a major source of microplastics entering waterways, better removal methods could reduce the amount of plastic pollution reaching the environment and eventually human food and water supplies.
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.
