Abstract

The objective of this work is focused on the preparation and characterization of plan microfiltration membrane Zn₃Al-Gh and the study of their efficiency in the treatment of ground water. This membrane was carried by using the support of the clay such as Ghassoul ‘Gh’ prepared by using dry uniaxial compaction method. The layered double hydroxides (LDH) based on Zn₃Al-CO₃with molar ratio (Zn²⁺/Al³⁺=3) was deposited on support by direct co-precipitation method.

The characterizations of the membrane LDH-Gh ‘Zn₃Al-Gh’ and deposited layer Zn₃Al-CO_3,was done by scanning electron microscopy analysis (SEM), X-ray diffraction (XRD), porosity and Fourier Transform Infrared Spectroscopy (FTIR),and shows that the deposition of the Zn₃Al-CO₃was carried on the Ghassoul support successfully. The chemical resistance and pure water permeability tests suggest the use of the Zn₃Al-Gh membrane for the microfiltration applications.

In this context, the performance of Zn₃Al-Gh membrane has been used in attempt to remove the indicator bacteria of fecal pollution, and eventually pathogenic bacteria in company with them, which are existing in groundwater of the urban commune “Sebaa-Ayoune” (Fez-Meknes region, Morocco). The analysis of the samples of water after and before microfiltration showed the bacteria removal is important for all germs indicating of fecal pollution. On the other hand, the diminution of the turbidity, the conductivity and the concentration of Ca²⁺, SO₄^2-, NO₃^- and NH₄⁺ were established.
