Failure to follow any instructions in this guide will void any warranty, if any exists.
PROTECTING THE MEMBRANE
When using the Membrane Decarbonator System, note the following information:
 The water temperature should not exceed 30° C (86° F).
 Air temperature should not exceed 30° C (86° F). If the air/amibient temperature exceeds 30°
C, the membrane life will be reduced.
 Remove free chlorine, ozone and any other oxidizing elements prior to the Liqui-Cel®
Membrane Contactor. Continuous chlorine levels should not exceed 1 ppm at 20° C (68° C).
The higher the concentration and temperature, the shorter the membrane service life.
Avoid contact with surfactants and alcohols when using our polypropylene membrane as they will
render the membrane hydrophilic. The membrane will need to be cleaned and dried before the
contactor can be put back into service.
Operating outside of these guidelines may negatively impact the membrane life.
MAINTAINING PERFORMANCE
Since water vapor and other volatile gases will pass through the membrane, the exhaust air from the
blower may become saturated with the vapor. Depending upon the ambient temperature,
condensation could occur in the outlet gas piping. Therefore, the outlet piping is sloped away from
the contactors. The condensation rate will depend on the liquid temperature. The warmer the liquid
stream, the higher the water-vapor transport rate. This condensation phenomenon is normal.
PROTECTING OTHER EQUIPMENT IN YOUR SYSTEM
If membrane failure occurs for any reason, water will flow to the air side of the membrane. This
would happen because the liquid is at a greater pressure than the air phase. In normal operating

mode, gases exit the membrane system at atmospheric pressure and in case of membrane failure,
water will flow out of the gas phase ports. The blower on the Membrane Decarbonator System is
protected from water damage since it has a liquid trap with a high water level cut-off switch
(located between the membrane contactor and the blower).
III. System Installation
A. Electrical Connections
WARNING
To reduce the risks associated with hazardous voltage:
 Ensure electrical connections are properly grounded.
 Always use a grounded power supply of appropriate voltage matching the system
voltage with fuse protection and a local disconnect switch.
 Always verify the appropriate electrical connections are used and are in
accordance with local electrical code and replace plug as necessary.
Select a location with adequate clearance from walls and other equipment to enable servicing of
the blower, membrane and other components. Allow at least (4) feet of clearance at the top of
the skid to accommodate membrane replacement.
A grounded power supply of the appropriate voltage matching the system blower voltage with a
15 amp fuse protection and a local disconnect switch is required.
If the skid was ordered for 110V (model SK-100-116), the 110V electrical plug will be attached.
For all other models (SK-100-216), the attached 220V plug may not match the customer’s
electrical connection. The customer is responsible for replacing this plug with the appropriate
plug for their electrical code. Refer to Figure 3 for the wiring diagrams.

Liqui-Cel® Membrane Contactors
Design & Operating Guidelines

Limited maintenance is required for Liqui-Cel® Membrane Contactors. We suggest a weekly or biweekly check of the system to verify it is operating as expected. For CO2 removal, a log should be
maintained to record critical information as shown in the example below. To measure the CO2
concentration, a colorimetric test kit is the simplest method. However, if the pH is < 3, the
colorimetric value will not reflect the actual CO2 removal. Another CO2 measurement system is
needed.
If the water pressure drop increases over time, it may be due to particulates accumulating in the
membrane contactor. Check the water inlet filter to ensure it is operating properly. If the blower
suction vacuum increases, that means the inlet air filter is clogged. If the CO2 removal % decreases,
it is due to scaling of the membrane and therefore should be cleaned.
Water accumulating in the water trap is normal, if it is due to water vapor condensation. It
should be drained on a regular basis to prevent the Hi Level limit switch from shutting off the
blower. However, if the level rises at an increasing rate, liquid may be passing through to the
gas side and replacement or cleaning may be needed.
This log will show the user a pattern of consistent performance or a decline in performance over
time. If the contactors are still performing to the stated performance, no maintenance is required. If a
decline in performance is noted, it may be time to clean the membrane. Cleaning is typically the only
maintenance required. See the 3M Cleaning Guide available online at www.Liqui-Cel.com.

A. Filtration Requirements
The inlet liquid and gas streams need to be filtered. The proper filtration
rating/arrangement will depend on the water source and, in many instances, filtration
alone will not provide sufficient protection to prevent membrane surface fouling, which
can negatively impact gas removal efficiency. Table 1 provides the minimum
recommended filtration guidelines to minimize potential membrane fouling and blockage
due to particles which will create a high pressure drop across the contactors and restrict
the flow through the contactor system. Additionally, some dissolved compounds found in
well, surface and city water will go through any filter and could potentially deposit on
membrane’s surface. DI water in combination with recommendations in table 1 will
provide a water quality that may help prevent system downtime.

The inlet air filter needs to be inspected regularly and replaced if needed. During
operation of the blower, its surface temperature can exceed 320° F (160° C) so do not
touch the unit. The discharge of the blower should be directed away from the operator to
prevent injuiry or other safety issues.

Design & Operating Guidelines
Membrane Fouling
When a Liqui-Cel® Membrane Contactor system is placed between a clarification unit and
an RO unit to remove CO2 from a water stream, watch for changes in water pH. Water
may contain species that are soluble in water in acidic pH ranges but insoluble in alkaline
pH ranges. If water pH increases as the water passes through the contactor (this
happens when dissolved CO2 is removed from water) the insoluble species might
precipitate on the membrane surface. Precipitation of solids can also occur when water is
treated with flocculation chemicals followed by a change in pH. For example, alum
(aluminum sulfate) is often used to remove suspended matter from water. The removal
takes place by coagulation, flocculation and precipitation in the water clarifier tank. The
precipitation occurs in the form of polymeric aluminum hydroxide at certain pH ranges. As
CO2 is removed from the feed water, a change in pH may be enough to precipitate
excess aluminum hydroxide or other ionic compounds on the membrane’s surface. The
thin coating or deposits will prevent normal gas transfer through the membrane and the
contactor’s removal efficiency will drop. This process is reversible by cleaning the
contactor with an acid solution such as 3% w/w ortho-phosphoric acid solution (refer to
the Liqui-Cel Membrane Contactor Cleaning Guidelines). The acid solution may dissolve
surface precipitates on membrane and will restore the contactor degassing performance
to original manufacturer's specifications.
When the contactors are installed downstream from carbon beds, a 2 micron absolute
filter should be installed and the carbon beds should be flushed to drain after the carbon
change-out until all carbon fines are flushed out. Care should also be taken when back
flushing carbon beds that are downstream of membrane contactors. Filtration should be
added to keep the contactors free from carbon particles, which can be difficult or
impossible to clean.
When Liqui-Cel Membrane Contactors are installed upstream of RO membranes, a
cleaning cycle is also recommended in order to prevent fouling of the Liqui-Cel
Membrane Contactor. Please refer to the Liqui-Cel Membrane Contactor Cleaning
Guidelines available on-line at www.Liqui-Cel.com or from your 3M representative.
