ClearUnderstanding 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.
Model analysis of electroflotation water treatment of wastewater containing microplastics
This study developed a mathematical model describing how electroflotation can remove microplastics from wastewater, identifying key factors affecting efficiency. Better process models help optimize treatment systems for removing plastic particles before they enter waterways.
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. Polystyrene was removed most efficiently, and adjusting pH, coagulant type, and dosage significantly improved removal rates, providing practical guidance for upgrading existing water treatment plants to better capture microplastics.
Microplastics Removal in a Dynamic Coagulation-Flocculation-Sedimentation System
Researchers compared microplastic removal during standard jar tests (batch) and continuous-flow flocculation systems, finding that flocculation mechanisms and removal efficiency differed significantly between the two setups. Conventional jar testing may overestimate microplastic removal because the flow conditions in real treatment plants are different. These findings have direct implications for designing more effective microplastic removal in full-scale water treatment facilities.
Impact of coagulation characteristics on the aggregation of microplastics in upper-ocean turbulence
This study investigated how coagulation conditions affect microplastic aggregation in water treatment, finding that coagulant type and dose significantly influence floc formation with plastic particles and ultimately removal efficiency.
Settling model to predict microplastics removal efficiency in wastewater treatments
A mathematical settling model was built to predict how efficiently wastewater treatment plants remove microplastics based on particle density, size, shape, and surface loading rates. The model shows that dense, large, spherical particles settle most readily, while light fibers and films are far harder to remove — providing treatment plant operators and engineers with a practical tool for optimizing processes to reduce the discharge of microplastics into rivers and coastal waters.
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.
Machine learning modeling of microplastics removal by coagulation in water and wastewater treatment
Researchers developed machine learning models to predict how effectively coagulation, a common water treatment process, can remove microplastics under different conditions. The best model achieved 96% accuracy and found that water temperature had the biggest negative effect on removal, while adding coagulant aids had the most positive effect. These tools could help water treatment plants optimize their processes to better remove microplastics from drinking water.
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.
Coagulation 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.
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.
