Ultrafiltration

The investigation was undertaken to evaluate the effectiveness of using activated carbon (AC) in conjunction with ultrafiltration (UF) in the removal of methylene blue (MB) from aqueous solutions. The combination of activated carbon with UF in this work was to exploit the high adsorption capabilitie

In China, many water supplies depend on conventional water treatment. Due to unfit soil and water conservation in some regions of China, conventional water treatment has showed some defects for the poor quality of water resource. In addition, advances in membrane technology and increasing requiremen

Increasing the fluid velocity in cross-flow membrane ultrafilter has two conflicting effects: one, the decrease in concentration polarization resistance, which is good for ultrafiltration; while the other, the decrease in average transmembrane pressure is bad for performance. Along the flow channel

Water from Lake Butoniga near the town of Buzet, Croatia, was used as a source for drinking water production. Since lake water has a high concentration of trihalomethane precursors, a treatment was necessary. A process including ozonation, flocculation and filtration was chosen on the basis of preli

Olive oil production results in important quantities of wastewater containing large amounts of total solids and organic carbon as well as low oil concentrations. This paper describes the treatment of olive mill wastewater (OMW) by combining an ultrafiltration (UF) technique and an advanced oxidation

The experience of the Canary Islands is unique in the world. In a very limited territory, all types of technologies and combinations can be found. The tertiary treatment installed in the waste water treatment plant of Barranco Seco (Gran Canaria, Canary Islands) has been designed with an ultrafiltra

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

It is now common knowledge that membrane filtration processes can be considered as high performance separation techniques, not only in laboratory experiments but also in many industrial applications. With its strong development for the production of large-scale drinking water, the ultrafiltration on

One of the most critical problems in developing countries is the lack of drinking water. People in these regions are supplied with surface water, which contains a significant amount of microorganisms that can cause several diseases. In fact, one of the main causes of infantile mortality is the high
