CF042A-FO Cell Manual
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.
5. Operation of the CF042A-FO Cell
