Journal ArticleDOI
Recent Advances in Chiral Resolution through Membrane‐Based Approaches
Journal ArticleDOI
Investigation of flow patterns and mass transfer in membrane module channels filled with flow-aligned spacers using computational fluid dynamics (CFD)
TL;DR: In this paper, a modified friction factor was introduced to investigate the effect of the hydrodynamic conditions in the channel on the shear stress at the walls, and the experimental results showed that the transition between laminar and transitional flow regime could be rigorously determined for the spacers under study.
Journal ArticleDOI
Removal of heavy metals from drinking water supplies through the ion exchange membrane bioreactor
TL;DR: The ion exchange membrane bioreactor process has a high potential for use in drinking water treatment systems, and offers numerous advantages over currently implemented processes, such as minimising the risk of secondary pollution of the drinking water.
Journal ArticleDOI
Stability of supported ionic liquid membranes as studied by X-ray photoelectron spectroscopy
Raquel Fortunato,Carlos A. M. Afonso,Juana Benavente,Enrique Rodríguez-Castellón,João G. Crespo +4 more
TL;DR: In this paper, the use of room temperature ionic liquids (RTILs) in supported liquid membranes (SLMs) has been evaluated and further studies were conducted in order to assess the SLMs' operational stability under dynamic conditions.
Journal ArticleDOI
Mercury removal from water streams through the ion exchange membrane bioreactor concept.
Adrian Oehmen,Dario Vergel,Joana Fradinho,Maria A.M. Reis,João G. Crespo,Svetlozar Velizarov +5 more
TL;DR: The IEMB process represents a novel mercury treatment technology with minimal generation of contaminated waste, thereby reducing the overall environmental impact of the process.
