Full TextAbstract
The influence of two-phase flow patterns especially slug and bubble patterns has been investigated in the recent studies of effect of gas injection on membrane fouling. The consequences demonstrate that slug flow is more effective than bubble flow in terms of enhancing shear force and permeate flux. In this paper, an experimental study is performed to investigate the fouling reduction in an ultrafiltration process using gas flow injection. The effect of slug and bubble patterns on permeate flux in the ultrafiltration process in a flat sheet module is analyzed with a video system facilitated with a high speed camera. The characteristics of bubbles such as their distribution and velocity are measured by image processing. The results show that the amounts of fluctuating and average velocity of the slug flow were larger than those of the bubble flow. The higher velocity of bubbles in the slug flow enhances permeate flux more.
