Start-up Procedures
for 3M™ Liqui-Cel™ MM 0.5x1 and 0.75x1 Series
Membrane Contactors
Prior to any start-up procedure, proper installation is required.
Please read and follow all safety information, warnings and instructions in this manual. Failure
to follow all product warnings and instructions could cause serious injury and property
damage. Retain these instructions for future reference.
Intended Use and Product Selection:
3M™ Liqui-Cel™ Membrane Contactors are intended to remove dissolved gasses and bubbles
from compatible liquids or to add gasses to a liquid stream. Liqui-Cel products are for use in
industrial separation applications of industrial fluids only, in accordance with the applicable
product instructions and specifications. 3M Liqui-Cel MM 0.5x1 and 0.75x1 Series Membrane
Contactors are not constructed of US FDA Title 21 CFR § 174-186 compliant materials. Not for
use in food contact applications.
Since there are many factors that can affect a product's use, the customer and user remains
responsible for determining whether the 3M product is suitable and appropriate for the user's
specific application, including user conducting an appropriate risk assessment and evaluating
the 3M product in user's application.
Restrictions on Use:
3M advises against the use of these 3M products in any application other than the stated
intended use(s), since other applications have not been evaluated by 3M and may result in an
unsafe or unintended condition. Do not use in any manner whereby the 3M product, or any
extractable or leachable from the 3M product, may become part of or remains in a medical
device, drug, cosmetic, or food or drink additive or supplement; or in applications involving
life-sustaining medical applications or prolonged contact with internal bodily fluids or tissues. If
you are considering using this 3M product for a restricted use, you must first contact 3M with
information about your proposed application to request prior written authorization for supply.
If your process may result in dangerous concentrations of explosive, flammable, toxic or
oxidizing liquids or gases in the membrane contactor or the system, contact 3M prior to use.

Mount contactor as shown below.
2.
Refer to start-up procedures below for each mode of operation.
Notes:
•
The liquid pressure should always be higher than the gas pressure inside the contactor.
•
Liquids entering the membrane contactor should be prefiltered at 5 micron absolute at
99.9% removal (beta 1000).

Start-up Procedures
A. General start-up instructions for the
liquid phase.
Note: Liquid flows on the shellside. The liquid
pressure should always be higher than the gas
phase pressure inside the contactor.
1.
Connect the liquid in/out ports and the
vacuum/sweep ports as shown in the
diagrams above.
2.
Slowly introduce liquid to the contactor,
making sure that the liquid inlet pressure
and liquid flow rate through the
contactor never exceed the respective
maximum operating limits.
B. General start-up instructions for the
sweep (strip) gas and vacuum phase.
Sweep (Strip) Gas Mode
(applies only to the 0.5 x 1 Contactor)
1. Set the gas pressure in the contactor to the
lowest possible level by adjusting the
appropriate valve in the gas delivery system.
2. Set the recommended sweep flow rate
by adjusting the appropriate valves. The
typical sweep gas flow rate range for the
0.5 x 1 is 50-500 std. cc/min.
3. Introduce sweep gas into the contactor.
Note: If using compressed air, make sure
it is oil free and air temp is < 35°C. A 0.2
micron filter is recommended with any gas.

Sweep (Strip) Gas with Vacuum (Combo)
Mode (applies only to the 0.5 x 1 Contactor)
1.
Set the gas delivery pressure to the
contactor at ≤ 1 psig (0.07 barg).
2.
Connect sweep gas to contactor via one of
the ports marked Vacuum or Sweep Gas.
3.
Start sweep flow and adjust flow rate by
adjusting the appropriate valve. Typical
sweep flow rate range for 0.5x1 in
combo mode is 10-100 Std cc/min.
4.
Connect vacuum to the contactor via
the second port marked Vacuum or
Sweep Gas.
5.
Start vacuum pump.
6.
Adjust absolute gas pressure on vacuum
side to desired level.
Vacuum Only Mode
1.
Start vacuum pump following vacuum
pump manufacturer's instructions.
2.
Apply vacuum to the membrane
contactor by opening the appropriate
valve. For MM-0.5x1 series membrane
contactors, vacuum can be applied to
both gas ports together, or to one port
while keeping the other port capped off.
3.
Adjust absolute gas pressure on the
vacuum side to the desired level at the
vacuum port on the contactor.
•
Gas entering the contactor should be filtered at 0.2 micron absolute at 99.9% removal
(beta 1000) for high-purity applications. Filtration at 1 micron absolute at 99.9% removal
(beta 1000) may be sufficient for industrial applications.
•
Upon initial start-up, flush all pipes to drain prior to introducing liquid into the membrane
contactors.
•
The vacuum pump and/or sweep gas should be on at all time unless the membrane
contactors are completely drained.
•
Liquid flows on shell side and sweep or vacuum are applied to the lumen side for these
3M Liqui-Cel MM-Series Membrane Contactors.
