Abstract
Extracting glutamic acid from waste sugar by AFC99 polyamide membrane with reverse osmosis was tested with increase in extraction percentage and producing efficiency. The results showed that the osmosis speed was directly proportional to liquid pressure and was related to flow velovity through membrane. Therefore, enlarging the liquid pressure and decreasing the concentration difference between the membrane and the main flow will result in raising the glutamic acid extracting rate and its producing efficienvy.
