Study of Modeling Transmembrane Pressure and Gel Resistance in Ultrafiltration of Oily Emulsion

This article deals with water removal from oil-in-water emulsion by an ultrafiltration membrane at different transmembrane pressures. The membrane intrinsic resistance and gel resistance are analyzed and determined based on the resistance-in-series theory. The experimental results show that the effect of pressure on the permeate flux depends greatly on variations...

Removal of Phenol From Wastewater by Different Separation Techniques

Application of membrane techniques (pervaporation and membrane-based solvent extraction) and adsorption to the removal of phenol from solutions modeling wastewater from phenol production by cumene oxidation process was investigated. The transport and separation properties of composite membranes PEBA, PERVAP 1060 and PERVAP 1070 in pervaporation of water-phenol mixtures were determined....

Modeling of the Conversion of Weak Organic Acids by Bipolar Membrane Electrodialysis

Organic acids are increasingly used for various industrial applications. Bipolar membrane electrodialysis EDBM can be used to achieve the conversion of the acid salt into its acidic form. Its introduction in replacement of precipitation can significantly lower the environmental impact of the process. This paper is focused on the modeling...
