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 dierent 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:
