one of the barriers during whey filtration using uf membrane is the fouling phenomenon of the membrane, which is caused by whey proteins. in this work, the uf membranes were prepared using polysufone (psf), dimethyl formamide (dmf), 1 wt.% poly vinyl pyrrolidone (pvp) and different concentrations of licl via phase inversion induced by immersion precipitation. the prepared membranes were charact...

Polymer-based membranes have advanced or novel functions in the various membrane separation processes for liquid and gaseous mixtures, such as gas separation, pervaporation (PV), reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), microfiltration (MF), other critical applications of water purification, solvent concentration, recovery [...]

Several ultrafiltration membranes of the anisotropic and isotropic type were characterized by means of the thermoporometry. Successive cooling and heating runs were performed in order to investigate the effects of the water-ice and ice-water phase transitions on the structure of the membranes. The results found for membranes having different casting thicknesses indicate that, in some cases, por...

In the era of freshwater scarcity, world seeks to limit overexploitation all accessible resource and also recover potable water by treating wastewater. Various domestic, agricultural industrial activities lead in generating high amount wastewater from which can be recovered for human needs. Over many years, conventional filtration process has gained success some extent effluents treatment dispo...

Conjugated polyaniline can impact the field of water filtration membranes due to its hydrophilic and antibacterial nature, facile inexpensive synthesis procedure, heat acid tolerance, unique doping/dedoping chemistry. However, gelation effect, rigid backbone, limited hydrophilicity severely restrict adaptability their antifouling performance. This Mini Review summarizes important works polyanil...

An effective method was developed for the preparation of Brucella abortus native hapten by use of an ultrafiltration system. The membranes PM30 and YM5 were used to separate the lipopolysaccharide and the native hapten. The yield of the native hapten was higher than that obtained by a more complex procedure reported previously. This method is economical for the large-scale preparation of B. abo...
