Surface Area

In the blending application mentioned previously on
page 3 the surface area of the Pall hydrophobic
membrane cartridge was approximately 120 times
the surface area of the flat sheet. This increased
surface area provides longer filter life and improved
water rejection.

Volume filtered
In many cases the filter can be undersized and this
may result in a number of filters being put in series to
“fix” the problem. We at Pall ensure that enough
surface area is proposed at the beginning to ensure a
realistic filter life for the unit.

What do you get with a bigger surface area?
This graph represents the exponential relationship
between the volume of liquid filtered and filtration area
under constant flow and media permeability conditions.
The exponent of the relation has been empirically
determined to be between 1.5 and 2.0.
Therefore, doubling available filter area should
essentially extend service life from 2.8 to 4.0 times.
At Pall we have recognised this need
and have developed a complete range
of filtration and separation equipment
to ensure that the samples presented
Pall Housings
All Pall filtration and separation equipment is
manufactured in several locations around the
globe so that continuity of supply is maintained the
coalescers and cartridges specified in this brochure
will have the same part numbers wherever they are
supplied from.
The housings that the coalescers and cartridges fit into
are manufactured locally to take account of local
specifications and requirements. In this case the
housing part numbers may be different to differentiate
these local requirements.

In discussions with many of our
customers around the world it is
increasingly evident that the
cleanliness of sampling systems
used for process product analysis
with analyser equipment is becoming
more critical. The need for a sampling
system to operate 24 hours a day
7 days a week means that the
sampling system equipment has to
be as reliable as that in the process
stream itself.

to the analysers are contaminant free.
Whether it is separation of liquid from
liquid, liquid from gas streams or
particulate removal from liquid or gas
streams Pall can provide an efficient cost
effective solution with payback from
investment being only a few weeks in
some cases.
A sampling system for process analysis
is generally a complex process that needs
to withdraw, transport, condition and
dispose of the sample fluid. When the
analyser is part of an automatic control
loop the reliability becomes even more
critical and the cleanliness of the sample
presented to the analyser paramount.
