| Abstract: | Membrane separation process of corn high steep-water were studied, Ultrafiltration(UF)combined with Reverse Osmosis(RO)was developed. The retain ratio of protein in concentrate solution passed through the RO membrane was 99.77%.The COD value of the permeate solution fell to 1000mg/L. And the permeate solution could be used as process water. The concentrate solution that retained by the RO membrane could be used as recovering valuable matters, such as lactic acid, and that retained by UF membrane could be made the thick corn liquid. |
