The objective of this powerpoint presentation was to optimize the aeration and backwash
methods 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 was
significantly 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 both
effective to control membrane fouling;
the energy consumption for aeration was much smaller for NAF
than for CAF; and,
this result suggests that NAF or PAF is required for low turbidity
feed water. However, both were not effective to retard membrane
fouling for the case of high turbidity feed water. Accordingly, IAF
seems to be useful for feed water with large variations of water
quality because they could reduce membrane fouling with
moderate energy consumption. Includes tables, figures.
