CF042A-FO Cell Manual
The CF042A-FO Cell is a laboratory-scale filtration unit that is designed to evaluate a variety
of engineered osmosis processes, including Forward Osmosis (FO), and Pressure Retarded
Osmosis (PRO). 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 CF042A-FO
Cell. Prior to operating or servicing this device, this manual must be read and understood.

The cell body consists of the tightening screws, cell top, membrane filter, O-rings, and cell
bottom. Figure 1 (see page 2) illustrates a typical assembly of the CF042A-FO. The CF042A-
FO is also packaged with a length of permeate tubing and membrane cutting template.
The CF042A-FO cell also requires additional equipment to operate that are sold separately:
* Modified Osmosis Insert is an accessory (sold separately) that is designed for experiments
where a dierential pressure is applied to the membrane sides, such as in a pressure-retarded
osmosis (PRO) process or pressure-assisted FO.

After verifying that all of the necessary components were shipped and present, you can begin
the assembly of the cell.
To assemble the CF042A-FO 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 bottom.
Caution: Do not depressurize the HP4750 Stirred Cell by loosening the couplings.
2. Place a piece of pre-cut membrane on to the cell bottom using the two alignment pins
to hold the membrane in position. The membrane should be installed with the shiny or
active side down facing the feed solution (bottom) in an FO process and facing the draw
solution (top) in a PRO process.
Note: If you are cutting your own membranes, the membrane’s outer edge should fit
between the inner and outer O-rings in the cell body to prevent leakage.
3. Place the cell top plate by aligning the two pins on the sides of the cell.
4. Insert one of the brass washers into each of the four holes at the corners of the cell top.
5. Secure the cell top by inserting and tightening one of the provided screws into each of
the corner holes.
The CF042A-FO Cell is now assembled and ready to be connected to a feed pump for
operation.

Figure 2 shows typical plumbing connections that need to be made for the operation of
the CF042A-FO Cell; the configuration can change slightly depending on the objectives of
the user. In general, the connections to be made are:
1. Feed tank to the feed pump
2. Pump outlet to the feed inlet of the cell body
3. Feed outlet of the cell body to the concentrate collection tank/feed tank
4. Draw solution tank to the draw solution pump
5. Draw solution pump outlet to the draw solution inlet of the cell body
6. Draw solution outlet of the cell body to the draw solution collection/draw tank
Figure 2 also lists the additional components that are necessary to operate the CF042AFO
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 forward osmosis system will vary with
the feed vessels, pumps, and tubing used.

Once the CF042A-FO Cell has been assembled and connected to a feed system, it can be
used in variety of applications that includes forward osmosis and pressure retarded osmosis.
To operate the CF042A-FO Cell:
To replace a member filter:
1. Open all of the valves in the system to relieve any pressure build-up before turning on the
feed pump.
2. Turn the feed and draw solution pump on.
3. Adjust the control valves (sold separately) to obtain the desired pressure and flow for feed
and draw solution.
Note: Experimentation enables you to determine the optimum settings for pressure, flow rate,
and shim/spacer combination to use on the chosen membrane and the fluid being processed.
4. Once the experiment is complete, shut down the system by turning the feed and draw
solution pumps o and opening all of the valves to relieve any pressure build up.
1. Turn the feed and draw solution pump OFF.
2. Open all of the valves in the system to relieve any pressure build up.
3. Loosen the screws in the cell top.
4. Separate the cell body top from the cell bottom.
5. Remove the membrane.
6. Install the new membrane.
7. Reassemble the cell top and bottom.
8. Secure the cell top to the cell bottom using the screws.
9. Turn the feed and draw solution pump on.

Parameters such as viscosity, pressure, and suspended solids may also aect performance/
operation. Experimentation with the CF042A-FO 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 an optional bypass valve and fitting on the pump outlet, which is not supplied
with the system.
The membranes, feed spacer, permeate, O-rings, and cell body materials construction dictate
the maximum operating temperatures.
