Fabrication, characterization and application of ceramic membrane developed from Tunisian natural kaolin clay for textile wastewater treatment are presented in this study. The morphology and properties of the resulting membrane sintered at 1000°C for 3 h were then determined by Scanning Electron Microscopy (SEM), mechanical and chemical resistance and water permeability. Separation performance of the membrane was evaluated during the treatment of textile wastewater. SEM images reveal the homogeneous surface of the membrane. The membrane displayed good chemical and mechanical resistances as well. Its permeability was of 21.2 L.h .m.bar, indicating that separation performance could occur in the domain of Ultrafiltration (UF). Performances of the membrane during the treatment of raw and biologically pretreated textile effluents are promising in terms of the removal of colour (99% for the raw effluent and 100% for the biologically pretreated effluent), chemical oxygen demand (COD) (80% for the raw effluent and 93% for the biologically pretreated effluent) and turbidity (98% for the raw effluent and 100% for the biologically pretreated effluent).
本文介绍了一种由突尼斯天然高岭土制备、表征及应用于纺织废水处理的陶瓷膜。研究了在 1000°C 下烧结 3 h 后所得膜的形貌和性能，通过扫描电子显微镜（SEM）、机械和化学阻力以及水渗透性进行了测定。考察了膜在处理纺织废水过程中的分离性能。SEM 图像显示出膜的均匀表面。该膜还表现出良好的耐化学性和机械性能。其渗透通量为 21.2 L.h-1.m-2.bar-1，表明分离性能可发生在超滤（UF）范围内。该膜在处理原水和生物预处理纺织废水时的性能在去除色度（原水为 99%，生物预处理后为 100%）、化学需氧量（COD）（原水为 80%，生物预处理后为 93%）和浊度（原水为 98%，生物预处理后为 100%）方面均有很好的效果。
