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

“…The fundamental distinction between ceramic membranes and conventional CWFs is rooted in their disparate filtration mechanisms and scope of application. − Conventional CWFs engage in physical filtration, a process contingent upon the exclusion of larger particulate matter, predicated on the pore structure’s ability to sieve particles at the particulate level. In juxtaposition, ceramic membranes operate through a sophisticated membrane filtration modality, proficient in the exclusion of finer particulate entities, as well as the sequestration of dissolved solids, bacteria, and viruses. − This advanced filtration is achieved through molecular sieving bolstered by surface chemical functionalities, facilitating interactions at the molecular scale, culminating in a more comprehensive purification paradigm. − Ceramic membranes offer superior filtration performance and improved separation efficiency and are used in industries with rigorous water quality standards. − …”

Synthesis, Characterization and Catalytic application of Mn-MFI prepared by Different Methods

“…There have been reports of the production of high-quality inorganic membranes for catalytic membrane reactors using isomorphous substituting the trivalent ions Al 3+ , B 3+ , Fe 3+ , and Ge 3+ for the Si 4+ ions in silicalite-1 14,15 . The high-silica aluminosilicate molecular sieve (zeolites) known as aluminumcontaining silicalite-1 (ZSM-5) exhibits significant importance as catalytic materials For the inclusion of manganese into silicalite-1, two synthetic techniques have been described 16,17 recrystallizing Mn(II)-exchanged magadiite into Mn-silicalite-1 18,19 .…”
