“…Dry and isostatic pressing are widely used in pressing processes [38][39][40][41]. The particles in the dry-pressing process extrude from each other to produce internal friction, which in turn acts on the powder particles to bond them more closely [42]. Its technological processes include feeding, compression, molding, billet, and mold cleaning, and it has a relatively simple operation.…”

Ceramic membranes have become one of the most rapidly developing and promising membrane materials owing to their excellent properties. Compared with other membrane materials, ceramic membranes are widely used in the wastewater and water treatment fields owing to their advantages, including higher chemical stability, stronger mechanical strength, longer service life, and better water filtration performance. In this paper, the sources of raw materials and their preparation for the production of ceramic membranes are briefly introduced. The methods for preparing ceramic membranes are described in detail, including the role of ceramic membranes in water treatment applications, the preparation methods of the membranes, and the latest progress in this area, along with a review of the applications of ceramic membranes in wastewater and water treatment. Simultaneously, this study also evaluates which preparation method is the most advantageous and the aspects of its advantages. The raw materials used in the ceramic membrane preparation and the types of water treatment suitable for this method were studied. The results showed that the phase-conversion sintering technique has multiple advantages, and the generated asymmetric structure with finger- and sponge-like voids can further improve the flux and separation abilities, which are attractive for scientific researchers. Finally, the development trends in the inorganic ceramic membrane market were surveyed. This work can help beginners understand the preparation procedures employed to produce ceramic membranes for water treatment; compare the porosity, mechanical strength, permeation flux, and chemical and thermal stability of the resulting membranes; and reasonably select the appropriate preparation method for the relevant water treatment type.

“…Slip casting follows a procedure similar to that for conventional CWF preparation. Tape casting is a widely used technique for producing thin and smooth ceramic sheets, involving pouring a ceramic powder suspension into a reservoir and passing a ceramic tape under an adjustable casting knife. − Pressing is commonly employed in fundamental research for fabricating ceramic membranes, where a dry powder is pressed by using a machine and then heat-treated. In the extrusion method, a mixture of ceramic materials and additives is made pliable and forced through a shaped opening to determine the membrane’s structure and properties .…”

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.

“…Due to the stable chemical properties of the ceramic membrane surface, it can avoid the adhesion of particles such as calcium sulfate with high viscosity in desulfurization wastewater. In the process of cross-flow filtration, the ceramic membrane can rinse opportunely to avoid excessive pollutants attached to the membrane surface and affecting the membrane flux [11]. At the same time, due to the stable surface properties, the pollutants covered on the surface are more likely to be washed away during the backwashing period, so the recovery effect of ceramic membrane flux after backwashing is also better [12].…”

According to the current zero-discharge requirements for wastewater in the power industry, based on the widely used membrane concentration technology, a pilot process for pretreatment of desulfurization wastewater is established at the Huaneng Yunhe Power Plant. The desulfurization wastewater from the triple-tank outlet is dealt with the ceramic membrane filtration or quartz sand filtration, activated carbon filtration, and tubular ultrafiltration respectively, the results prove that the ceramic membrane process can substitute the traditional quartz sand filtration, activated carbon filtration, and tubular ultrafiltration process, which not only can significantly reduce the construction scale and floor area, but also reduce the treatment costs per ton of water. At the same time, aiming to reuse desulfurization wastewater, a higher water recovery rate is obtained by the ceramic membrane process, and the anti-pollution performance of the ceramic membrane is better. Therefore, pretreating desulfurization wastewater through a ceramic membrane is a more reasonable pretreatment process.
