Removing mixture salts from dye solutions using membrane technology still need to be improved for high dye rejection and low salt rejection. In this work, ceramic membrane with pore size of 1.5nm presented a satisfactory desalination of dye solutions containing NaCl and Na2SO4 compared with two commercial organic nanofiltration membrane elements (DK and DL). Effect of salt content, salt type, molar...
This work describes manufacturing of low-cost tubular ceramic microfiltration membrane made from natural pozzolan. Firstly, the tubular ceramic support was prepared by extrusion technique followed by sintering at low temperature of 950 °C. The extruded paste is essentially composed of pozzolan powder (<200μm), clay (<68μm), some organic additives and water. This formulation is conducted to obtain...
