| Abstract: | It was described that the change regularity of membrane permeation flux during the ultrafiltration of filtrate treated by five kind of different pretreatment process.By comparing the change of HA concentration and molecular weight which the sample was pretreated before and after.The change of the flux that was also compared that membrane had used to filter the filtrate before and after as well as the membrane washed by enzymes solution.It was discussed that the regularity of membrane polluted and the method of preventing. |
