Pilot Study on Dosing Suspended Fillers to Alleviate Membrane Fouling

Abstract:

In this article, Vertical A/O-MBR was used as the experimental device to study membrane fouling through dosing cylindrical rigid suspended fillers, and the best conditions for membrane fouling control and effluent quality with fillers was discussed. Results showed that the critical flux zone decreased. When the MLSS was 5g/L and the suspended fillers dose was 1%, 5%, 10%, respectively, TMP increased rapidly with the quantity, greater quantity of fillers speeded up the membrane fouling process, and in small quantity membrane fouling had some delay action. The best dosing of fillers was determined as 7% in the condition of MLSS=5g/L, and the effluent quality was good.
