“…The degree of contact between the particles increases as the sintering temperature increases, and as a result, neck formation starts and further leads to the densification of the membrane. [ 16 ] Figure 1 depicts the entire process of membrane synthesis. The cenosphere membrane was prepared using the uniaxial pressing technique.…”

“…The synthesized membrane, which was sintered at 1000°C, has pores with a size of 0.6 m. The membrane was used for microfiltration application. [ 16 ] Fly ash and kaolin have been used by Rawat and Bulasara [ 17 ] to produce a low‐cost ceramic membrane, which was then employed to separate humic acid from water. The amount of kaolin and fly ash utilized throughout the synthesis determined the best membrane preparation.…”

Ceramic membranes are now receiving greater attention and are regarded as the best alternative option for reducing energy use. There are currently a number of limitations on the use of ceramic membranes, including high raw material costs and high sintering temperatures during synthesis. Cost‐effective raw materials were employed in the synthesis of ceramic membranes to get around these restrictions. Utilizing a straightforward pressing technique, circular disc‐type membranes were prepared. To assess the membrane properties, the impact of sintering temperatures between 700 and 900°C was examined. By varying the sintering temperature, the average membrane pore diameter was observed. The membrane, which was sintered at 800°C, had pores that were on average 110 nm in size. Furthermore, the porosity of these synthesized membranes ranged from 22% to 35% with an average pore diameter of 74–121 nm. These manufactured membranes showed very good chemical stability when both acidic and basic solutions were used. Various characterization methods, including thermogravimetric analysis (TGA), x‐ray diffraction analysis (XRD), and scanning electron microscopy (SEM), were used. Thermo‐gravimetric investigation revealed that the synthesized cenosphere membrane required a minimum sintering temperature of about 700°C. The flux measured with deionized water and the applied transmembrane pressure showed an upward trend. The impact of sintering temperature on permeate flux was investigated. The results showed that as the sintering temperature increased from 700°C to 900°C, the flux reduced. It was determined that the synthesized membrane cost ₹1618.80/m2.

The need for water is increasing owing to the rapidly increasing world population, urbanization, industrialization, global climate changes, and intensive agricultural activities. While the importance of water is increasing day by day, the purification and reuse of water have become more and more essential. Reducing the pollutants at the source as much as possible and if it will be given to the receiving environment, giving the wastewater treatment in accordance with the current discharge regulations, are priority processes. Of the advanced separation methods, membrane separation technology is used to reduce water resource use and control environmental pollution and has advantages such as high separation efficiency, convenient operation, compact equipment, and energy-saving. Membranes are divided into two categories according to their structures: organic and inorganic membranes (or ceramic membranes). Compared to organic membranes, inorganic membranes have many advantages such as high thermal and chemical stability, good resistance to microbial erosion, easy regeneration and cleaning, high mechanical strength, and long-term stability in harsh conditions. The high cost of ceramic membranes is an important disadvantage. In recent years, it is seen that membrane production costs are reduced by using natural minerals such as kaolin, quartz, bauxite, diatomite, clay, limestone, dolomite, zeolite, and industrial wastes instead of the commonly used ceramic membrane raw materials. By using these raw materials, besides reducing the cost of ceramic membranes, it also contributes to lowering the temperatures required for their production. In this study, studies on ceramic membranes produced from industrial wastes (waste ash, sawdust, sewage sludge, construction and demolition wastes, waste diatomite, rice husk ash, sugarcane pulp ash, corn cob ash waste etc.) were examined.
