Suction Effects on the Hydrodynamics in the Vicinity of an Ultrafiltration Plane Ceramic Membrane

Popis výsledku v původním jazyce

The wall shear stress is determined at the surface of a plane ceramic ultrafiltration membrane in a tangential ultrafiltration module. In a first time, the shear stresses are determined at the surface of a plate of Plexiglas mimicking a membrane and at the plane membrane surface without fouling particles with the aim to investigate the influence of permeation. In a second time, the wall shear stress is determined at the surface of the plane membrane during the ultrafiltration of a suspension of spherical no compressible particles inducing a deposit at the membrane surface. In order to study the influence of the foulant, two concentrations of particles were used for the experiments. The values of the mean wall shear stress and its fluctuations (turbulent intensity rate) were measured by using an electrochemical method. 20 microelectrodes, on which an electrochemical reaction occurs, are mounted flush to the plate of Plexiglas and to the surface of the membrane to determine the maps of s
