Ubiquitous microplastics, sources, impacts, and treatment: Importance of cost-effective ceramic membranes for MPs removal
AI summary Read the abstract
This review examines the sources, environmental impacts, and treatment methods for microplastic contamination, with a focus on ceramic membrane filtration. Researchers found that while conventional treatment methods have limitations, ceramic membranes offer cost-effective and durable performance for removing microplastics from water. The study highlights the widespread presence of microplastics across environmental compartments and the urgent need for scalable removal technologies.
Microplastics (MPs) contamination is one of today's most stern environmental challenges, resulting from enormous tonnes of plastic production. Since MPs are present in all forms, i.e., fragments, fibres, spheres, films, and pellets; they are released into the environment from personal care products, wastewater treatment plants, laundry, etc., even in minute doses of 10 μg/ml. MPs are found in various secretions and fluids of the human body, animals, and plants. Industrial effluents were treated for MPs using conventional methods such as coagulation with flocculation, electrochemical, adsorption, advanced oxidation process, etc. Still, membrane technology is considered the best in treating wastewater, and it is eco-friendly, has low power consumption, and has a tremendous dissolution efficacy of >99%. Ceramic membrane, in particular, offers several benefits, including high-quality thermal and chemical balance, natural stamina, fouling hostility, and sturdiness. These attributes make ceramic membranes more suitable than polymeric membranes for wastewater operation. Thus, the high cost of basic materials and the need for soaring sintering temperatures have made ceramic membranes expensive. As a result, researchers are focusing on developing ceramic membranes from other cost-effective materials to decrease costs. These cost-effective ceramic membranes empower them to retain the benefits of ceramic materials while drastically lowering their manufacturing costs. This review seeks to provide a trailblazing overview of the existence, providence, and effects of MPs in the environment and also different physical, chemical, and biological treatment technologies opted to treat the MPs with emphasis on the importance of cost-effective ceramic membranes for separation of MPs from various media. • Microplastics, Sources, Impacts, and Treatment elaborately presented • Observed membrane technology as one of the viable treatment systems for MPs • Emphasized the importance of cost-effective ceramic membrane for MPs removal

Membrane Technologies for Microplastics Removal from Wastewater: Recent Progress, Fouling Mechanisms, and Future Perspectives
AI summary Read the abstract
Tiny plastic particles called microplastics are slipping through our wastewater treatment plants and ending up back in the environment—and potentially in our food and water—because standard filtering methods aren't fine enough to catch them. This review paper rounds up the latest research on advanced filter membranes that can trap these particles more effectively, while also tackling a key problem: the membranes tend to get clogged by the plastics they're filtering out. While these technologies aren't yet perfected or widely deployed, they represent a promising step toward cleaner water and reduced human exposure to microplastics, which have been linked to potential health concerns.
