Sepa
CF II Membrane Cell
System Principles of Operation
The permeate carrier is
placed into the Cell Body Top, which fits over the Guideposts. Guidepost
location assures proper orientation of the cell body halves.
The cell body is inserted into the Cell Holder. Hydraulic pressure
is applied to the bottom of the holder. This pressure causes the
piston to extend upward and compress the cell body against the Cell
Holder top. Double O-Rings in the cell body provide a leak-proof
seal.
The feed stream is pumped from the user supplied Feed Vessel to
the Feed Inlet. The Feed Inlet is located on the Cell Body Bottom.
Flow continues through a manifold into the membrane cavity. Once
in the cavity, the solution flows tangentially across the Membrane
surface. Solution flow is fully user controlled and is laminar or
turbulent depending on the feed spacer and the fluid velocity used.
A single piece of rectangular-Membrane is installed in the Cell
Body Bottom on top of the Feed Spacer and Shim (optional). Precut
membranes from Sterlitech or flat sheet membrane from any source
may be used. Guideposts assure proper alignment of the membrane.
A portion of the solution permeates the Membrane and flows through
the Permeate Carrier, which is located in the Cell Body Top. The
permeate flows to the center of the Cell Body Top, is collected
in a manifold, and then flows out through the Permeate Outlet connection
into a user supplied Permeate Collection Vessel. The concentrate
stream, which contains the material rejected by the membrane, continues
sweeping over the Membrane and collects in the manifold. The concentrate
then flows through the Concentrate Flow Control Valve into a user-supplied
vessel or back into the Feed Vessel as shown above.
Sepa-CF II Material of Construction Fluid Compatibility
The Cell Body is available in 316 stainless steel. Feed Fluids of
strong acids may attack the cell body.
