Abstract

A study of the effect of particulate solids on mass transport behaviour in cross-corrugated membrane systems is reported. The electrochemical limiting current technique was employed to determine the mass transfer coefficients. The influence of cross-corrugated structures, to simulate membranes, and the effect of the orientation of flow to the angle of corrugation (0°, 45° and 90°) on the mass transfer coefficient is reported. The effect of particulate solids on mass transport was investigated using SiO2, at concentrations of up to 0.2 wt %. The presence of SiO2, at a concentration lower than 0.2%, gave higher values of mass transfer coefficient compared to those in the absence of the solid. The mass transport correlations showed that even at low values of Reynolds number there is evidence of turbulence.
