Abstract: |
|
The factors of aeration rate , on/off ratio, backflushing flow and membrane flux had important roles on the fouling of submerged ultrafiltration membrane. Orthogonal experiment was used to find out the remarkable influence function among these factors, the results of the variance analysis showed that the factors of aeration rate and on/off ratio had a significant influence on membrane fouling, and the factor of backflushing flow had a slight influence, while the factor of membrane flux had no influence on the membrane fouling. The obtained optimal parameters were; aeration rate 4 Nm3/h;on/ off ratio 16 min/2 min,;backflushing flow which is 80 % of water yield and membrane flux 55 LMH. The module can run steadily in the optimum condition for 3-4 days before chemical cleaning. |
