Treatment of textile wastewater using conventional methods is either inefficient or costly. This is because it usually involves reactive dye, great amounts of salt and high temperature. In this study, a bimodal porous silica/(-alumina membrane with improved permeability was tested in dye–salt water separation. The effects of temperature, feed concentration of dye, feed concentration of salt, pH...
Previously undescribed oligosaccharides in bovine cheese whey permeate were characterized by a combination of nanoelectrospray Fourier Transform Ion Cyclotron Resonance (nESI-FTICR) mass spectrometry and matrix-assisted laser desorption/ionization Fourier transform ion cyclotron resonance (MALDI-FTICR) mass spectrometry. Oligosaccharide composition was elucidated by collision-induced dissociati...
 A model is developed for separation of multicomponent gas mixtures in a countercurrent hollow fiber membrane module. While the modelâs solution in countercurrent module usually involves in a time consuming iterative procedure, a proper initial guess is proposed for beginning the calculation and a simple procedure is introduced for correcting the guesses, hereby the CPU time is decreased ess...
