ClearUnderstanding and Improving Microplastic Removal during Water Treatment: Impact of Coagulation and Flocculation

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.
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.
