Page 3: Introduction
Sepa CF Cell Manual 1. Introduction The Sepa CF Cell is a laboratory-scale crossflow filtration unit designed to evaluate the performance of 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. By using a combination of stainless steel (SS) shims, feed spacers, and membranes, users can vary the operating conditions and fluid dynamics over broad ranges. -

3. Sepa CF Cell Assembly After verifying that all the necessary components were shipped and present, you can begin the assembly of the Sepa CF Cell. 3.1 Cell Body Assembly The cell body consists of the cell top, membrane filter, feed spacer/ permeate carriers (optional), shims (optional), O-rings, and cell bottom. - Page 7 Sepa CF Cell Manual To assemble the Sepa CF Cell Body: 1. Connect the concentrate flow control valve to the cell bottom by wrapping PTFE tape around the valve’s male NPT end and screwing it into the concentrate outletport. Note: The cell bottom is the half of the cell body that has the four alignment pins. The cell top has the holes to accept the alignment pins.
- Page 8 Sepa CF Cell Manual 4. Install the feed spacer into the central cavity, on top of the shim. The feed spacer must lie flat and be fully contained within thecavity. Note: The feed spacer and the permeate carrier look similar and are cut in the same size. The permeate carrier is thinner and has a tight weave while the feed spacer has large gridding.
- Page 9 Sepa CF Cell Manual 6. Wet the permeate carrier with water or the fluid to be processed and place it into the cavity in the cell top. The surface tension caused by wetting the carrier will keep it in place.
- Page 10 3.2 Cell Holder Assembly The cell holder is filled with Mobil DTE 20 Series Hydraulic Oil to operate the hydraulic piston. Before using the Sepa CF Cell for the first time, the brass quick release connector must be installed into the cell holder.

Page 14: Supplementary Operating Information
Sepa CF Cell Manual 5. Supplementary Operating Information 5.1. Membrane Performance Results 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 an excessive pressure differential across the membrane and possible damage. -
