An Experimental and Theoretical Study on Separations by Vacuum Membrane Distillation Employing Hollow-Fiber Modules

An experimental study of solar thermal vacuum membrane distillation desalination

An experimental desalination system coupling a vacuum membrane distillation (VMD) unit and a vacuum tube solar heat collection (SHC) unit was developed and tested. The parametric sensitivity of the VMD unit performance was investigated first using an electric heater as the heat source, and then the whole system was examined using solar heat. It was revealed that hot feed temperatures higher tha...

An Experimental Study on the Oily Wastewaters Treatment by Polyethersulfone (PES) Nanostructure Hollow Fiber Membranes

Oily wastewaters from oil refineries and oil distribution centers are one of the most important environmental concerns in recent decades; therefore, it is critical to treat these types of wastewaters. In this study, the performance of different polyethersulfone hollow fiber membranes in oily wastewaters treatment was investigated and the effects of operating conditions such as transmembrane pre...

Novel designs for improving the performance of hollow fiber membrane distillation modules

Experimental Study on Concentration of Aqueous Lithium Bromide Solution by Vacuum Membrane Distillation Process

This study aims to investigate the applicability of vacuum membrane distillation for concentrating aqueous lithium bromide solution, and to analyze the feasibility of applying vacuum membrane distillation process to the absorption refrigeration system. Hydrophobic polyvinylidene fluoride (PVDF) was adopted as the membrane material, and was made into hollow fiber membrane module. Commercial aque...
