"Membrane Technologies for Industrial Effluents Valorization : Water Treatment to Reuse and Added-value Resources Recovery"
In recent years, various removal methods have been developed for the treatment of pollutants containing in wastewater such as chemical precipitation, membrane filtration, adsorption, dialysis/electrodialysis… Among this methods, we choose to work with ceramic microfiltration and ultrafiltration membranes made from natural material: phosphate, clays... due to its abundance in Morocco.
The filtration test of salts solutions performed with different ultrafiltration ceramic membranes show that salt rejection depend on the charge of the ions, pH, salt nature and concentration. The rejection mechanism depends on the relative ratio of the coulombic, dielectric and hydration interaction between the material and the ionic species.
We will focus in this presentation on the elaboration and characterization of microfiltration and ultrafiltration ceramic membranes and their application to remove salts and textile dyes in water. -
