【Abstract】 The polysulphone ultraftitration memberane made by the authors is used to study the separation of dispersing dye solution by means of ultrafiltration memberane in plate memberane ultrafiltrafion trough. The authors analysed the efects of pressure difference, flow velocity on membcrane surface, and solution concentration and studied the memberane stability under the condition of high temperature and different pH value. This technique can be used to separate the industrial waste water containing dispersing dye which is dischanged from textile dyeing mills.更多还原
