The alumina microfiltration(MF) membrane was modified with nanocrystalline TiO2 in the pore wall. The electrokinetic properties of unmodified and modified alumina membranes were characterized by streaming potential measurements during tangential filtration at various conditions of pH, ionic concentr

There has been a growing interest in the use of inorganic membrane for several industrial and laboratory applications. This is because they offer many advantages over organic counterparts in separation processes. These include resistance to compaction under high pressure, chemical stability at high

Desalination of seawater and NaCl solutions is of great interest as potable water sources are dramatically declining on earth. Most of the techniques used to decontaminate water involve polymeric membranes and expensive desalination processes. To improve thermal, chemical and physical resistance of

Microfiltration membrane is increasingly used in wastewater treatment to produce a higer quality effluent. In this study a microfiltration membrane from Tunisian clay (JM18/SI2) was used to treat cuttlefish effluents generated from the conditioning (freezing and washing) seawater food industry which

The filtration tests of electrolyte solutions performed with different ceramic membranes show that salt rejection depends on pH, salt nature and concentration. A simple correlation between streaming potential and rejection rates exits and confirms that streaming potential is a relevant parameter to

The use of inorganic membranes in pollution treatment is actually limited by the cost of such membranes. Advantages of inorganic membranes over organic ones are their chemical, thermal and pH resistance. In this study, low cost ZnAl2O4-TiO2 ultrafiltration membranes were tested for removing Cd(NO3)2

A milk factory sited at Boudouaou (40 km from Algiers) rejects a great quantity of effluent which contains soft whey. 8,000 l are treated twice a week and are rejected into a river which supplies drinking water to the town population. Some analyses have shown an increase in the water acidity and bot

The use of ceramic membrane in liquid pollution treatment is actually limited due to the price of ceramic membrane, nevertheless these membranes are more resistant to solvent, pH and oxidation. In this work the preparation of low cost TiO2(50%)-ZnAl2O4(50%) membranes deposited on an artificial cordi

The filtration tests of electrolyte solutions performed with different ceramic membranes show that salt rejection depends on pH, salt nature and concentration. A simple correlation between streaming potential and rejection rates exits and confirms that streaming potential is a relevant parameter to

Supports for microfiltration and ultrafiltration were prepared with Tunisian silty marls. Plastic pastes were prepared from a ceramic powder of silty marls mixed with organic additives and water. The pastes could be extruded to elaborate a porous tubular configuration. The supports fired at 1190°C a
