INSTRUCTIONS FOR USE
ACTIVASORB® Depth Filter Sheets
Installation of ACTIVASORB® depth filter sheets
Before use, check the filter sheet conditions. Defective filter sheets
should not be used. The sheets must be inserted with the unfil-
trate side (inlet/rough side) against the non-filtrating elements
or frames and the filtrating side (outlet/fine side) against the
filtrating elements of the filter.
NOTE
For the NOVOX® ST and OD plate and frame filter
press, the filter sheets must be centered and cover
all sides of the elements so that they protrude a
few millimeters above the filter elements.
Wetting the filter sheets
a) Gently press the plate and frame filter (approx. 50 % pressing
power)
b) Fill the filter with water (e. g. tap water or WFI) by slowly
opening the inlet keeping the venting valves open
c) Once purged, open the outlet valve to drain and close the
venting valves, adjust the filter pressing power as required
d) Apply back pressure of about 0.2 bar (2.9 psi) by closing the
filter outlet slightly
e) Rinse for 5 minutes to wet all filter sheets
f) Stop the water supply and close the filter pack with full power
For manually operated, smaller filters, the wetting of the filter
sheets can also be carried from the outside.
Rinsing the filter sheets
g) Use 50 L/m² of a process-compatible solution (e. g. WFI) indica-
tively (might variate depending on ACTIVASORB® grade)
h) The rinsing flow rate shall be approximately 350 L/m²
If rinsing is not desired or tolerated (insoluble products such as
high percentage distillates or oils), the product to be filtered may
be first recirculated to remove possible small fibers and/or diato-
mite particles.
Sterilization
i) Slightly open (release) the plate and frame filter press (to ease
the materials expansion due to the increasing temperature)
j) Fill the system with water, slightly open all outlet valves
k) Heat up the filter until the required sterilization temperature of
85 °C is reached at all outlet valves
l) Maintain temperature for minimum 20 minutes
m) Turn off the hot water supply
n) Cool the filter down gradually to room temperature with cold
sterile water while recirculating it into the system
To save energy, it is recommended in step k) and l) to heat up
during recirculation.
NOTE
Sterilization is not fully completed until all parts to
come into contact with the product have been
sterilized. For alternative sterilisation methods,
please contact your FILTROX representative.

Filtration
o) Slowly start filling the filter by opening the inlet valve and all
venting valves (ensure complete venting), the outlet valve
should be closed
p) Once properly vented, open the outlet valve, close the venting
valves and start the filtration (if required, the initial filtered
volume may be separated from filtrate to avoid dilution with
rinsing water)
q) Adjust to the flow rate to 150 L/m²
process needs
r) Ensure continuous and uniform flow rate
s) Avoid any abrupt changes in filtration flow, pressure shocks,
gas bubbles, as well as stop and go
NOTE
Observe the maximum recommended flow rate,
operating pressure and temperatures. Further
information can be found in the corresponding
technical data sheet.
Regeneration
Once saturated and the filtration is no longer in accordance with
the requirements, the depth filter sheets are to be considered
exhausted and cannnot be regenerated.
Replacement of filter sheets
The ACTIVASORB® depth filter sheets must be replaced as soon as
the filtration-treatment requirements are no longer fulfilled. The
filtered volumes vary depending on the products, process target,
flow rate as well as ACTIVASORB® grade.

Note on disposal
The respective official regulations for disposal must be followed,
depending on the filtered product. Uncontaminated sheets can
be disposed of as non-hazardous waste. Please refer to your local
environmental authority for more information.
Shelf life and storage
The filter sheets should be stored in their original packaging in a
dry, odor-free and well-ventilated area. Temperature fluctuations
can lead to condensation formation and should therefore be
avoided. The filter sheets are intended for immediate use. Filter
sheets for food & beverages should be used within 60 months
from date of manufacture. Filter sheets for life science applica-
tions should be used within 36 months from date of manufacture.
Further information can be found on the corresponding technical
data sheet for filter media.
