Development of Mesoporous Composite Ceramic Membranes from Low Cost Materials: Application to Water Treatment
One of the challenges for development of inorganic membranes are to produce low-cost membranes from natural materials such as clay, Sand, Zeolite and apatite which are in abundance, need lower firing temperature than pure metal oxide and subsequently, low energy consumption. In this presentation, particular attention is paid to the development and application of new low cost porous ceramic membranes made particularly from natural materials and also from nanocomposites of clay for nanocomposite UF membrane preparation. In this case, the mesoporous active layer is deposited on tubular microporous supports via several techniques such as dip-coating or layer - by- layer.
The efficiency of the prepared membranes is evaluated by the application to the treatment of different types of wastewater coming from different sectors, for water desalination and remediation of industrial effluents.
