Low-Cost Antibacterial Ceramic Water Filters for Decentralized Water Treatment: Advances and Practical Applications

Abstract

Access to clean water remains challenging for people living in underdeveloped regions, rural areas, and remote locations. In the absence of centralized water treatment systems, point-of-use (POU) solutions are necessary. Ceramic water filters (CWFs) have emerged as a practical and affordable option for decentralized water treatment. This review focuses on recent advances in antibacterial CWFs, including preparation methods, filtration performance, and applications. The review highlights the significance of preparation techniques, material choices, and additives in determining CWF properties and performance. Despite virus and chemical contaminant removal limitations, ongoing research on nanofillers and antibacterial additives shows promise for enhancing the CWF performance. The costeffectiveness, ease of production, and low operational requirements of CWF make it a viable solution for decentralized drinking water systems, particularly in resource-limited areas. Studies have demonstrated the efficacy of CWFs in reducing water contaminants, but proper maintenance and user training are crucial to optimal performance.

PSf Membrane-Impregnated Jute–Copper Nanocomposite as Highly Efficient Dye Removal Material

“…In recent years, nanocomposite materials, including polymeric nanocomposites, have emerged as promising candidates for wastewater treatment due to their exceptional adsorption, catalytic, and antimicrobial properties. , These materials, composed of a combination of nanoscale particles and a polymeric matrix, offer enhanced performance and efficiency compared with traditional treatment methods. Nanocomposites exhibit high surface-area-to-volume ratios and tenable surface properties, making them ideal for the adsorption and degradation of various pollutants present in wastewater. , …”
