Effects of microbubbles in precoat filtration
When the diameter of a microscopic bubble is less than 50 μm, it is referred to as microbubble (MB). The properties of MB are different from those of bubbles whose diameter is more than 50 μm. For instance, MB has the negatively charged surface and the self-pressurization effect. Because of the...

| description | When the diameter of a microscopic bubble is less
than 50 μm, it is referred to as microbubble (MB).
The properties of MB are different from those of
bubbles whose diameter is more than 50 μm. For
instance, MB has the negatively charged surface and
the self-pressurization effect. Because of these
properties of MB, it is used in some processes such
as wastewater treatment or aquatic environmental
remediation.
It has been reported that when diluted slurry of
FeO(OH) is filtered in precoat layer containing MB
at a constant rate, the filtration time becomes more
than twice longer compared to that of conventional
precoat filtration. This technique can decrease the
frequency of filter medium cleaning and reprecoating,
resulting in a cost reduction of precoat
filtration. However, it has not been clarified why the
addition of MB to the precoat layer lengthen the
filtration cycle. In this study, we discuss the effects
of MB on precoat layer prepared by MB body
feeding to kieselguhr slurry. |
