Hydrodynamics

Bio-fouling is the principal problem met with membrane filtration in biological suspensions treatment, in particular in the case of membranes made of sintered clay which have a low resistance to chemical washing; we are interesting, in this work, to the bioadhesion which is the cause. At first, by t

A new multi-effect plate evaporator, EasyMED, is presented. This patented process [1] is applicable for seawater desalination using simple and modular technology. Experimental results from the hydrodynamics and thermal performances obtained with a one-effect laboratory unit with 0.4 m3/d distilled w

The aim of this work is to characterize more accurately, through experimental or theoretical approaches, the hydrodynamics of three particular systems usually used for flux enhancement: shear-enhanced filtration with a vibrating membrane module, gas/liquid two-phase flows and Dean vortices. The corr

It is known that the performance of membrane filtration depends on the coupling of mass transfer and fluid mechanics within membrane modules. The influence of cross corrugated membranes, and the orientation of flow to the angle of corrugation (90°, 45°, and 0°) on the mass transfer coefficients has

Air sparging has shown to be very efficient for flux enhancement in different membrane processes and for different membrane geometries. This study focuses on the application of air sparging to nanofiltration flat sheet membranes and aims to understand which hydrodynamic parameter is responsible for
