This study investigates a novel method for food waste management by using it as a sustainable replacement for conventional pore-forming agents in ceramic membrane production. The membranes were analyzed using various techniques, including X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and a universal testing machine. The morphologies of the membranes were observed using scan electron microscopy (SEM). The effects of particle size (45-125 μm), pore-forming agent (5-20 wt%), and sintering temperature (900-1150 °C) on the porosity and mechanical strength of the membranes were investigated using the Design of Experiments (DoE) and Response Surface Methodology (RSM). The optimized membrane was evaluated for its performance in filtering industrial textile wastewater. It achieved impressive results, with approximately 98.4 % removal of turbidity and 71.3 % removal of chemical oxygen demand. This research paves the way for optimizing ceramic membrane fabrication using upcycled food waste, promoting sustainability and offering potential solutions for both food waste management and industrial wastewater treatment challenges.
本研究探讨了一种新颖的食物垃圾管理方法，即将食物垃圾用作陶瓷膜生产中常规成孔剂的可持续替代品。使用 X 射线衍射（XRD）、傅里叶变换红外光谱（FT-IR）、热重分析（TGA）和万能试验机等各种技术对膜进行了分析。通过扫描电子显微镜（SEM）观察了膜的形态。使用实验设计（DoE）和响应面法（RSM）研究了粒径（45-125μm）、成孔剂（5-20wt%）和烧结温度（900-1150°C）对膜的孔隙率和机械强度的影响。对优化后的膜进行了过滤工业纺织废水性能评估。它取得了令人印象深刻的结果，浊度去除率约为 98.4%，化学需氧量去除率为 71.3%。这项研究为使用可回收食物垃圾优化陶瓷膜制造铺平了道路，促进了可持续性，并为食物垃圾管理和工业废水处理挑战提供了潜在的解决方案。
