BOOTH NO : I4
Category : Manufacturing Technologies
Ceramic membranes, superior to polymers, offer robustness, thermal stability, and fouling resistance. Industries leverage ceramics' chemical resistance and mechanical strength, aiding desalination and pre-treatment. Superior hydrophilicity and stability against fouling mark ceramic membranes. Pervaporation, a distinct separation process, involves hydrophilic membranes under vacuum, different from reverse osmosis. Effective separation relies on vacuum-driven vaporization. Ceramic membranes enhance pervaporation efficiency, with composite membranes showing promise. A novel approach integrates ceramic hollow fibers with ZnO nanoparticles and PVA for saltwater desalination. The concept involves phase inversion, forming an asymmetric structure, followed by nanoparticle deposition and hydrophilic membrane polymerization. The resulting phase change within the ceramic hollow fiber aids desalination, a breakthrough for efficient salt separation.
The lack of a polymer-ceramic composite hollow fiber membrane for pervaporation desalination using room temperature feed and vacuum suction presents a significant research gap. Ceramic membranes' advantages, including robustness, stability, and low fouling, have garnered attention. Despite progress, challenges persist in developing efficient pervaporation processes, particularly for desalination. The proposed study aims to address these gaps by utilizing a novel approach involving ceramic hollow fibers with ZnO nanoparticles and PVA for saltwater desalination. The process involves phase inversion and nanoparticle deposition, exploiting the microstructure of the ceramic hollow fiber to enable efficient desalination at ambient temperature and low pressure. This study seeks to contribute to the advancement of pervaporation technology and its application in seawater desalination.
