Recycling solid industrial wastes into valuable materials is always the priority solution in waste management. In this perspective, sugar scum and fly ash were used to produce an effective low-cost porous ceramic membrane. The impacts of the sintering temperature, amount of sugar scum, and sintering time on the properties of the prepared ceramic membrane were investigated and optimized using experimental design. A simultaneous rise in both the sintering temperature and the amount of sugar scum leads to a notable increase in porosity. Moreover, the simultaneous increase or decrease in the time and the amount of sugar scum causes a significant decrease in the compressive strength. The optimal conditions have been determined as a sintering temperature of 1197 °C, a sugar scum amount of 12.06 %, and a sintering time of 253 min. Under these conditions, the density, porosity, and compressive strength were found to be 2.16 g/cm³, 34.66 %, and 28.24 MPa, respectively. In addition, the obtained ceramic membrane has a water permeability of 2356.68 L/h m bar, a pore size in the range 0-4.5 μm, and excellent chemical resistance in both acidic and basic media. Finally, the performance of the prepared ceramic membrane was evaluated by the filtration of methylene blue. The results indicate that sugar scum and fly ash are suitable precursors to manufacture an effective ceramic membrane for the treatment of wastewater.
将固体工业废料回收转化为有价值的材料一直是废物管理中的首要解决方案。从这个角度来看，糖渣和粉煤灰被用于生产一种有效的低成本多孔陶瓷膜。利用实验设计研究并优化了烧结温度、糖渣用量和烧结时间对所制备陶瓷膜性能的影响。烧结温度和糖渣用量同时升高会导致孔隙率显著增加。此外，时间和糖渣用量同时增加或减少会导致抗压强度显著降低。已确定最佳条件为烧结温度1197℃、糖渣用量12.06%、烧结时间253分钟。在这些条件下，发现密度、孔隙率和抗压强度分别为2.16g/cm³、34.66%和28.24MPa。此外，所获得的陶瓷膜具有2356.68L/h m bar的水渗透性、0-4.5μm范围内的孔径，并且在酸性和碱性介质中均具有优异的耐化学性。最后，通过对亚甲基蓝的过滤评估了所制备陶瓷膜的性能。结果表明，糖渣和粉煤灰是制造用于处理废水的有效陶瓷膜的合适前驱体。
