Despite the membrane incompatibility, results from the MEDKR reaction show that there is great potential for the MEDKR system if improved base resistant OSN membrane can be produced. Therefore new base resistant OSN membranes are currently being developed in order to produce a more robust MEDKR proc

Thin-film composite membranes in contrast to asymmetric membranes allow using expensive or rare materials for the selective layer. The polymer of the selective layer can be crosslinked before or after deposition, different modifiers, including inorganic nanoparticles can be introduced into the polym

In the present paper we illustrate applications of a new set of force balance equations able to predict the average size of a droplet forming during cross-flow membrane emulsification processes. These balance equations allow to correlate the droplet diameters with the advancing and receding contact

A good shortcut design method of tubular membrane modules provides a more accurate estimate of the size or area of the module required for a given separation duty and hence its cost. A previous shortcut design method based on the cross-flow nature of the membrane developed by the author considered o

In this study, a stage-2 spiral-wound nanofiltration (NF) system was used to further treat the permeate produced by a stage-1 tubular NF employed for treatment of dyestuff wastewater. Pilot-scale experiments were carried out to select the appropriate commercial NF membranes by investigating the TOC

This experimental and simulation work allows the establishment of relationships between the physicochemical properties of aroma compound molecules and the extraction efficiency. Indeed, the best configuration of the membrane modules was also determined in regards to the aroma compounds properties.

In recent years the study of new materials in the field of catalysis has been attracted the attention of scientific world in order to prepare catalysts more stable, selective and with the possibility of their easy recovery and recycle. In this work we investigated the preparation and characterizatio
