| Abstract: | The fouling mechanism and cleaning methods for ceramic membrane in clarification of traditional Chinese medicine extract were studied. The influence of membrane materials on fouling was investigated. Aluminum membrane is a proper one in treating traditional Chinese medicine extract. The pollutants deposited on the membrane surface during the microfiltration were determined by IR spectroscopy. The fouling mechanism was analyzed with the results of SEM, EDX and ICP. The effect of several cleaning agents and cleaning time on the recovery of permeate flux were investigated. The solution with 2% NaClO was the best cleaning agent. |
