Description
The objective of this powerpoint presentation was to optimize the aeration and backwashmethods to minimize membrane fouling and energy consumption for submerged microfiltration (SMF)process. Experimental methods included: non-aeration filtration; periodic aeration filtration; and, continuance aeration filtration. Experimental materials are presented along with comparisons of aeration methods. The experimental results indicate that: the extent of fouling wassignificantly dependent on water quality and aeration methods;the major foulant was mainly particles in summer;feed water turbidity was less than 30 NTU, CAF and PAF were botheffective to control membrane fouling;the energy consumption for aeration was much smaller for NAFthan for CAF; and,this result suggests that NAF or PAF is required for low turbidityfeed water. However, both were not effective to retard membranefouling for the case of high turbidity feed water. Accordingly, IAFseems to be useful for feed water with large variations of waterquality because they could reduce membrane fouling withmoderate energy consumption. Includes tables, figures.
