The insights from this study allow fast membrane development for specific applications. With pore size, membrane thickness and hydrophobicity/ oleophobicity are adjustable on demand. The tested membranes show good performance in liquid–liquid extraction. State of the art in membrane contactors are p

The hollow-fiber module (cross flow) in combination with activated carbon showed almost no flux decline and a good performance independent of particle size or distribution. The presence of particles led to the abrasion of the fouling layer and helped to prevent its possible growth and consequent blo

This organic nanocomposite membrane is readily processed via “Trojan horse” method compared to the conventional MMMs [5]. The thin selective layer can be easily fabricated on the supporting materials to form the composite structure in order to obtain the high flux. The increased performance in ethan

Thus, it is shown that counter-current mode of MC operating is preferable for high separation efficiency. The proposed RMC for biogas separation provides the methane purity >95% under low energy consuming. For air dehumidification, the contactor system providing dew point below –30° C is developed.

The developed model gives a good agreement of calculated and experimental data. The role of membrane control keeps important even under currents close to the limiting current that gives reasons for improving membrane selectivity properties.

Behaviour of rubbery (PDMS) polymeric matrix containing MOFs is different due to glassy (PSf) polmer. Flexibility of the chains in elastomer allow higher loading of the filler in the matrix. The gas separations abilities of the fabricated organic molecular sieve membranes show improvement in permeab

Application of in-line coagulation/ultrafiltration process with the use of alum or polyaluminum chloride resulted in improved removal of NOM from treated water and reduced membrane fouling. It seems that the investigated

We propose in this study the effectiveness of an organic membrane Nanomax50 charged negatively on complex solution tanneries. Our choice was made on the solutions of tanning and liming of the tannery tawing of Rouïba/Algiers because of the nature of the substances which they contain, namely chromium
