In the present study, the effect of zirconia powder content, polyvinyl alcohol (PVA), Contact time and sintering temperature of zirconia microfiltration membrane elaboration were evaluated using Plackett-Burman design (PBD) and investigated by thickness and pore diameter. The zirconia microfiltration membrane has been prepared by the powder suspension technique. A deflocculated suspension of zirconia was obtained by mixing (5-10% w/w) of zirconia, (30-35% w/w) of PVA (12% w/w aqueous solution) as binder and water. The zirconia layer was deposited on the inner surface of clay support by slip casting with a contact time (2-5 min). After drying at room temperature, the ZrO2 membrane was sintered (800-1000°C) for 2 hours. By using PBD, sintering temperature, PVA and zirconia were recognized and selected as important effectives parameters of pore diameter; On the other hand, PVA and contact time were the main controlling parameters of the thickness of zirconia microfiltration layer. The optimal factors to elaborate the microfiltration membrane by using experimental design include a sintering temperature of 1000°C, zirconia content of 5%, PVA content of 30% and contact time of 2 min predicting a pores diameter of 0,24 µm and thickness of 24 µm.

With the increase in demand for commodities in the world, it is advisable to conserve resources. In the case of liquid wastes generated from pharmaceutical and petroleum industries, an unconventional solution is provided for the regeneration of solvents. However, this solvent recovery can be carried out using various efficient methods. Recently, Mixed Matrix Membranes (MMM) obtained by the addition of nanoparticles into a polymer matrix as reinforcements, or using a material with a well-defined inorganic network as a membrane like zeolite, silica based, Zeolite imidazolate frameworks (ZIFs) and Metal organic frameworks (MOFs), were explored for a solvent recovery process. These membranes possess characteristics such as high selectivity, flux and stability at various environmental conditions for the solvent recovery process. In this review, we have covered the polymer, nanocomposites, and ceramic membranes for solvent recovery through the pervaporation and organic solvent nanofiltration processes. The key challenges faced by the materials such as MOFs, zeolite, silica, zeolite and ZIFs when they are fabricated (through in situ synthesis or secondary growth process) as membranes and separation of solvents to explore for the solvent recovery process are reviewed.

“…Therefore microfiltration (MF) separation is widely used as a solid-liquid separation technique in the drink and food industries and in biotechnology. The microfiltration membrane we made from natural Moroccan clay [1][2][3] and phosphate [4] show their potentialities in the rationalization of productions systems. Their intrinsic characteristics of efficiency, operational simplicity and flexibility, relatively high selectivity and permeability for the transport of specific components, low energy requirements, good stability under a wide spectrum of operating conditions, easy control and scale up have been confirmed in a large variety of application, and operations.…”

Study of coupling photocatalysis and membrane separation using tubular ceramic membrane made from natural Moroccan clay and phosphate

This paper is devoted to study the feasibility of combining photocatalytic degradation with membrane filtration for the removal of organic pollutants. As a result, we have successfully prepared lowcost microfiltration membranes based on clay and phosphate. It is expected that the phosphate and clay composite membrane can have multifunctional separation and photocatalysis simultaneously and this type of composite membrane can play an important role in the photocatalytic reaction in presence of TiO2 and the separation process. We then tested the efficiency of the direct coupling of photodegradation and filtration to determine the rate of release of TiO 2 particles through the microfiltration membrane. However, we have seen that the recovery of TiO 2 exceeds a 96%, as well as the removal of products from the photodecomposition of the reaction mixture in the membrane photocatalytic reactor. In our case the methylene blue elimination rate exceeds 75%.
