| Abstract: | As a high efficient, low energy expense and easily operated separation technology, membrane separation technology has been widely and large-scale used in the water treatment, but membrane pollution is a bottleneck in its use. In the paper, we introduced the current techniques used to enhance membrane permeation flux, analyzed the theory of permeation flux significantly enhanced by gas/liquid two-phase flow, the development of its theory and problems probably met in application. In water treatment, the application of gas/liquid two-phase flow used to enhance membrane permeation will be more and more. |
