| Abstract: | [Objective] To pre-assess the ultrafiltration treatment of potato starch wastement and make preparation for furthur adopting PES membrane to treat potato starch wastewater.[Method] Potato starch wastewater was prepared through simulating potato starch production,and then treated by 4 kD,6 kD,10 kD and 20 kD molecular weight cutoff of PES membrane,retention rates,COD,protein concentration of feedstock and discharge were analyzed.[Result] Compared with the retention rate of COD and protein,the best molecular weight cutoff was elected.[Conclusion]The assessment was completed. |
| Keywords: | Best molecular weight cutoff PES membrane Ultra filtration Potato Sarch wastewate |
