摘要：This work was conducted to evaluate the starch addition on some physicalcharacteristics of flat ceramic microfiltration membranes made from Moroccanpozzolan. Natural pozzolan was characterized by X-ray fluorescence, X-ray diffractionand Thermo-gravimetric analysis. The starch was added as porosity agent and itsamount was varied from 0 to 20 wt.%. Membranes were prepared by dry process usinguniaxial pressing method and followed by sintering at temperature of 950 °C. Obtainedmembranes were characterized by scanning electron microscopy, water porosity,mechanical strength, and water permeability. The experimental results indicate thataddition of starch to natural pozzolan increases the porosity, pore size, and permeabilityof the membrane but accompanied by a decrease of the flexural mechanical strength.The promising aspect of the obtained results allowed using these membranes as filtersfor clarification of local industrial textile effluent.
