“…The active ultrafiltration layer from kaolin was prepared by a slip casting process on kaolin support from a mixture of the inorganic powder and a 12 wt.% aqueous solution of polyvinylique alcohol (PVA) (Rhodoviol 25/140 (Prolabo)), which is used as binder and plasticizer. The slip casting process [42,52] was applied to coat the support tube to elaborate ultrafiltration membrane as described in Figure 1.…”

This work concerns to the development and characterization of support and ultrafiltration membranes from naturally occurring-kaolin clays as principal components. The preparation and characterization of porous tubular supports, using kaolin powder with corn starch as poreforming agent, were reported. It has been found that the average pore size was about 1 μm while the pore volume was 44% for supports sintered at 1150°C with a flexural strength of about 15 MPa. The deposition of the active layer was performed by slip casting method. The rheological study of various coatings with different concentration of kaolin powder, polyvinyl alcohol (PVA) and water under different conditions regarding temperature and stirring time was done. After drying at room temperature for 24 h, the membrane was sintered at 650°C. The average pore diameter of the active layer was 11 nm and the thickness was around 9 µm. The determination of the water permeability shows a value of 78 l/h.m 2 .bar. This membrane can be used for crossflow ultrafiltration. The application of the cuttlefish effluent treatment shows an important decrease of turbidity, inferior to 1.5 NTU and chemical organic demand (COD), retention rate of about 87%. So, it seems that this membrane is suitable to use for wastewater treatment.

“…Nevertheless, the membrane pore size can be reduced via surface modification of the membrane by crosslink age using various polymers (Rameeetse et al, 2019;Mathaba and Daramola,2019); embedding nanoparticles within the polymer matrix (Daramola et al,2015) or coating with nanoparticles as the active layer (Kasemset et al,2017;Wan et al,2017). In this context, a large number of research works has been devoted to the development of new types of inorganic membranes from low cost materials (Aloulou et al,2018) and (Tahri et al,2013). Majority of these studies concentrated on the application of (UF) membranes in pollution preventionSaffaj et al(2010).…”

The objective of this work is focused on the preparation and characterization of plan microfiltration membrane Zn 3 Al-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 Zn 3 Al-CO 3 with molar ratio (Zn 2+ /Al 3+ =3) was deposited on support by direct co-precipitation method. The characterizations of the membrane LDH-Gh 'Zn 3 Al-Gh' and deposited layer Zn 3 Al-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 Zn 3 Al-CO 3 was carried on the Ghassoul support successfully. The chemical resistance and pure water permeability tests suggest the use of the Zn 3 Al-Gh membrane for the microfiltration applications. In this context, the performance of Zn 3 Al-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 Ca 2+ , SO 4 2-, NO 3 and NH 4 + were established.
