| Summary: | This work presents the preparation of microfiltration (MF) membranes deposited on highly porous supports tailored for microfiltration applications. The supports were prepared from local Algerian clays and calcium carbonate, selected for their abundant availability. Subsequently, these supports underwent coating with microfiltration membrane using the slip casting method employing the same clay powder. The resulting membrane, sintered at 1100°C, exhibited desirable attributes including a thickness of approximately 27 μm and an average pore size (APS) value of about 0.42 μm, coupled with notable adhesion between the support and the membrane. Furthermore, physicochemical and microbiological tests were conducted on water samples to confirm the effectiveness of the membrane in microfiltration. The results show that the membrane is highly effective in removing turbidity, with a rejection rate of approximately 99%. The pH and conductivity of the water remain stable during filtration. Additionally, the membrane demonstrates significant efficiency in removing heavy metals, with rejection rates of about 68% for iron and 90% for aluminium, as well as it is effective in removing specific bacteria from water. |
