3.6 Height of the tanks relative to the
PAUL
®
unit
Before assembling the
PAUL
®
station
, it is essential to determine the exact
three-dimensional position of all three tanks, i.e. the
RWT
,
PAUL
®
and the
FWT
, to assure that all connections between the tanks fit and fulfil specific re-
strictions and the hoses are long enough.
The only requirement concerning positioning is that we recommend minimum
distances in height, as can be seen from Figure 2.
Figure 2:
requirements concerning height of tanks and
PAUL
®
unit
Please note that increasing the height difference between the bottom of
PAUL
®
and the inlet into the FWT will increase the transmembrane pressure TMP. This
results in higher flow, but it also might speed up pore blocking in the membrane,
so please do not use this simple possibility to increase water production to a
large extent.

> 0.50 m
*3
*1
: This can best be more than 0.50 m, as
this will assure that influent flow into PAUL
will always be sufficient high.
Note:
if the height difference is very high,
(> 10 m estimated), then the OPV (part of
the PCU) must be the „high pressure“
version – please indicate when ordering!
*2
: The bottom of the PAUL unit should at
least be
15 to 20 cm higher
than the inlet
into the FWT (in no case lower than the inlet
into the FWT).
*3
: water cans must fit under the taps.
Note:
delivery flow can be increased by
adding a local pipe/hose system and placing
the taps as low as possible beneath the FWT
bottom.
