Preparation and characterization of flat membrane support based on Sahara Moroccan clay: Application to the filtration of textile effluents

Abstract

The present paper is devoted to synthesis of porous ceramic support from local Sahara Moroccan clay. This material is characterized by its natural abundance and its beneficial properties. The support with flat configuration was prepared from natural clay. The powder was crushed and sieved to 125 µm. The extrusion was performed by applying the uniaxial pressing. SEM, XRD, and DTG characterizations techniques were used. The elaborated flat support sintered at 950°C showed apparent porosity and water absorption of 40.81% and 25.25%, respectively. The water permeability of elaborated support is about 121 L/(h m 2 bar) after 2 h of filtration. The support performance was evaluated by filtration of textile effluents with a good retention of suspended particles present in textile effluents.
