Effects of microbubble-bodyfeeding on filtration properties of clay suspension
Microscopic bubbles with diameter of 1 ~ 50 μm are generally called microbubbles and have different behaviors from ordinary bubbles. For example, very long stagnation, pressurized interior gas due to surface tension and free radical generation under water are characteristics of microbubbles. I...

| description | Microscopic bubbles with diameter of 1 ~ 50 μm are
generally called microbubbles and have different
behaviors from ordinary bubbles. For example, very
long stagnation, pressurized interior gas due to
surface tension and free radical generation under
water are characteristics of microbubbles.
In cross-flow filtration of river water with UF
membrane module, the filtration flux was increased
by generating microbubbles in the water [1], while in
dead-end cartridge filtration, microbubblebodyfeeding
enhanced detachability of filter cake [2].
The reasons for these phenomena have not been
clarified yet.
In this study, we conducted mainly two constantpressure
filtration experiments, i.e. filtration with a
cylindrical cartridge filter and upward filtration with
a planar filter. In the latter experiment, filtrate flows
in the direction opposite to gravity. We compare the
detachabilities of filter cake as well as filtration
properties of suspensions with and without
microbubbles, and discuss the effects of
microbubbles on filtration process. |
