Abstract
This work reports the development and characterization of a new ceramic MF membrane. The flat membrane was prepared from natural Bentonite extracted from the vicinity of Nador, Morocco. X-ray fluorescence (XRF), X-ray diffraction (XRD) and thermogravimetric analysis (TGA) techniques were used for the characterization of the raw material. Flat disks of 37.1mm in diameter and 1.6mm in thickness were obtained by uniaxial pressing method, followed by sintering at 950°C. The resulting membrane was characterized by Environmental Scanning Electron Microscopy (ESEM), water porosity and mechanical strength. The porosity of this membrane is 32.12% with a mean pore size of 1.70μm. The water permeability of elaborated membrane is 520L/(hm2bar) after 2h of filtration. The membrane presents good mechanical properties with flexural strength of 22MPa. The microfiltration membrane was tested in industrial effluents treatment with a nice retention (94–99%) of suspended particles present in wastewater.
