Synergistic Removal of Microplastics and Organic Matter in Desalination by Ferrous Iron/peracetic Acid System
AI summary Read the abstract
Researchers found that a ferrous iron/peracetic acid oxidation system synergistically removes both microplastics and humic acid organic matter from seawater during desalination pretreatment, outperforming individual removal of either contaminant alone. Effective microplastic removal from seawater desalination systems is critical for ensuring that drinking water produced from ocean sources does not carry microplastic contamination into human consumption.
Microplastics (MPs) have become an emerging pollutant in the oceans. We found that in seawater with both MPs and humic acids (HA), the Modified Fouling Index (MFI) values were much greater than the superposition of MPs only and HA only, and that MPs and HA formed a...

Removal of microplastics from water by using magnetic sedimentation
AI summary Read the abstract
"Researchers demonstrated that magnetic Fe-C-NH2 nanoparticles added to water can attach to polyethylene and PET microplastics, forming heteroaggregates that are then removed by a gradient magnetic field, achieving effective extraction of both plastic types from model aqueous suspensions. This green magnetic sedimentation approach offers a scalable, chemical-free pathway for removing microplastics from drinking water or wastewater effluent, with direct implications for reducing human ingestion of plastic particles."

Study on the Impact and Mechanism of Microplastics on the Coagulation-Coupled Ultrafiltration Process in Seawater Desalination Pretreatment
AI summary Read the abstract
This study systematically analyzed how microplastics interact with and disrupt the coagulation-coupled ultrafiltration process used in seawater desalination pretreatment, identifying fouling mechanisms and performance impacts. As desalination becomes a critical freshwater source globally, understanding and mitigating microplastic interference in treatment processes is essential for producing drinking water free from plastic contamination.
The Removal of Polypropylene Microplastics in Simulated Water Enriched with Organic Substances Through the Electrocoagulation Process
AI summary Read the abstract
Researchers tested electrocoagulation as a treatment method for removing polypropylene microplastics from simulated domestic wastewater enriched with organic substances in a Peruvian context, demonstrating effective removal under controlled conditions. This approach addresses a critical gap in wastewater infrastructure in developing regions, where untreated microplastic-laden water directly contaminates drinking sources and food-producing water bodies.
