Abstract: Experimental investigation
of the microfiltration
(MF) using
an revolving cross-flow membrane filter was conducted under constant
pressure
difference condition, and
different flat membranes made
of polyvinyliden difloride (PVDF,
0.1 μm), cellulose
acetate (CA,
0.22 μm), sulfonated
polyethersulfone
(SPES, 0.22
μm) and
polyamide
(PA,
0.45 μm), respectively, were used
in filtration
experiments.
The
dependence of the cross-flow MF rate and the filtrated volume on time were
measured on-line. The experimental results
showed that the effect
of
the cross-flow on high viscosity
medium
was
more apparent than that
on the low
viscosity one.
