The CF047/CF090 Cell is a laboratory-scale crossflow filtration unit that is designed to
evaluate flat sheet membranes in a variety of applications. It simulates the flow dynamics of
larger, commercially available membrane elements such as industrial spiral wound membrane
elements. Users can vary the operating conditions and fluid dynamics over broad ranges.
Table 1 outlines the operational parameters and technical specifications of the
CF047/CF090 Cell.
Prior to operating or servicing this device, this manual must be read and understood.
Table 1: CF047/CF090 Features and Technical Specification
* Note: Maximum Pressure and Temperature ratings are dependent on a variety of factors involved in
MPD testing. Listed values are guidelines based upon material properties and cannot be guaranteed in
every application.

The CF047/CF090 cell also requires additional equipment to operate that are sold separately:
• Feed Pump
• Feed Tank
• Filtration membrane packs
• Flow control valves
• High pressure hoses
• Pressure gauges
2.1. Additional Equipment
After verifying that all the necessary components were shipped and present, you can begin
the assembly of the crossflow cell.
3. CF047/CF090 Cell Assembly
To assemble the CF047/CF090 crossflow cell:
1. Wet the O-rings with a small amount of water or the fluid to be processed and install
them into the grooves on the cell top.
Caution: Ensure the O-rings lie flat in the grooves of the cell top. Leaking may occur if the
O-rings do not lie flat in the grooves. The O-rings will be cut or crushed when the system is
operating if the O-rings are not installed correctly.

5
CF047/CF090 Cell Manual

2. Place piece of pre-cut membrane inside the cell top, centered over the inner o-ring. The
membrane should be installed with the shiny or active side down toward the cavity in the
cell top.
3. Place the sintered metal support disk on top of the membrane to hold the membrane in
place.
Note: When cutting membranes, ensure the membrane diameter extends past the outer
edge of the inner O-ring to prevent leakage.

6

4. Place the cell bottom on the assembled cell top
5. Use the 3-inch high pressure coupling to clamp the cell bottom to the cell body.
Tighten the high pressure coupling with 27 Nm (20 ft-lb) of torque for 69 bar (1000 psig)
operation.

6. Flip the cell over and install the feed inlet/outlet and permeate fittings as shown, if
they have not been previously installed. Use PTFE tape and thread sealant when installing
fittings into the cell.
7. The CF047/CF090 Crossflow Cell is now assembled and ready for operation.

Figure 2 shows typical plumbing connections that need to be made for the operation of the
CF047/CF090 Cell; the configuration can change slightly depending on the objectives of the
user. In general, the connections to be made are:
Figure 2 also lists the additional components that are necessary to operate the CF047/
CF090 cell. These components are sold separately and can be found in the Membrane/
Process Development section of the Sterlitech website (http://www.sterlitech.com/membrane-
processdevelopment.html). The final assembly of the crossflow system will vary with the feed
vessels, pumps, and tubing used.
Note: A good starting point may be to set the system at 1.7 bar (25 psig) pressure for
ultrafiltration or 17.2 bar (250 psig) for reverse osmosis. If this does not produce the desired
results then the parameters can easily be adjusted and dierent membranes can be used.
1. Feed vessel to the pump inlet
2. Pump outlet to the feed inlet of the cell body
3. Concentrate outlet of the cell body to the feed vessel
4. Permeate outlet to the permeate collection vessel
1. Open all the valves in the system to relieve any pressure build-up before turning on the
feed pump.
2. Turn the feed pump on.
3. Adjust the flow using the by-pass line or by adjusting the pump speed.
4. Adjust the concentrate/back pressure control valve to obtain the desired pressure.
5. Once the experiment is complete, shut down the system by turning the feed pump o
and opening all of the valves to relieve any pressure build up.
5. Operation Of The CF047/CF090 Cell
Once the CF047/CF090 Cell has been assembled and connected to a feed system, it can be
used in variety of applications that includes reverse osmosis, ultrafiltration, nanofiltration, and
microfiltration.
To operate the CF047/CF090 Cell:

10
CF047/CF090 Cell Manual

Spiral wound membranes containing mesh spacers are usually operated with a fluid velocity
across the membrane surface of 0.1–0.5 m/sec (0.3–1.6 ft/sec). Higher velocities in membranes
may lead to excessive pressure dierential across the membrane and possible damage. Hollow
fiber membranes, tubular membranes, and membranes with
tubular spacers may be operated at higher velocities, but this may not contribute to a more
eective operation.
Other parameters such as viscosity, pressure, and suspended solids may also aect
performance/operation. Experimentation with the CF047/CF090 Cell can help predict the
best operating parameters. If your pump is delivering too much flow, a portion of the flow can
be diverted back to the feed container before entering the feed inlet of the cell body. This
requires installation of a bypass valve and fitting on the pump outlet (Figure 2, #8).
To replace a membrane filter:
1. Turn the feed flow pump OFF.
2. Open all the valves in the system to relieve any pressure build up.
3. Open the high-pressure clamp
4. Separate the cell body top from the cell bottom.
5. Remove the support disk and the used membrane.
6. Install the new membrane, followed by the support disk.
7. Reassemble the cell top and bottom.
8. Secure the cell top to the cell bottom using the high-pressure clamp.
9. Reconnect inlet, outlet, and permeate fittings to the cell as required. Resume operation
as outlined above.

The membrane, O-rings, and cell body materials construction dictate the maximum operating
temperatures. Listed values are guidelines based upon material properties.
The CF047/CF090 Cell can be cleaned easily after the membrane is removed. However,
you may wish to simulate the actual cleaning conditions of Cleaning-In-Place (CIP) in larger
systems with spiral-wound or tubular membranes. This can be done with CIP. Clean-In- Place
chemically cleans without removing the membrane to mechanically scrub the unit.
During CIP, cleaning solutions are re-circulated and, in some cases, allowed to sit for a period
of time within the cell body. In some cases, the feed pump can be used to re- circulate the
cleaning solutions.
