【 摘 要 】

Theimpact of two-phase flow onto the flux of the permeate in microfiltration oftwo sorbents-Bentonite and Lewatit S1468-with and without adsorbed zinc, wasexamined. Two different types of membrane, single-and multi-channel, based onα-Al₂O₃, were used. In single-channel membraneapplication of aeration increased the permeate flux by 13 and 29% withoutadsorbed zinc and by 22 and 25% with adsorbed zinc for Bentonite suspension andby 4 and 5.5% both with and without adsorbed zinc for Lewatit S1468 compared tosingle-phase (without aeration) flow at 1.4 and 2.2 m s^-1 of the gaseous phase rate, respectively. In multi-channel membrane thepermeate flux increased not significantly without adsorbed zinc and by 22 and25% with adsorbed zinc for Bentonite and by 12 and 13% without adsorbed zincand not significantly with adsorbed zinc for Lewatit S1468 at 0.4 and 1.1 m s^-1 of the gaseous phase rate, respectively.
