SEPA* CF II

Membrane Cell System

Fact Sheet

Description and Use

GE Water & Process Technologies Sepa* CF II Mem­brane Cell system is a lab quality crossflow mem­brane filtration unit capable of withstanding up to
1,000 PSIG (69 bar). It provides fast and accurate
performance data for any reverse osmosis,
nanofiltration, ultrafiltration or microfiltration cross­flow application. (Figures 1 and 2)

Versatile Operational Capabilities to Fit a Wide
Range of Applications

Sepa CF II has a unique, patented design that simu­lates the flow dynamics of larger, commercially
available membrane elements. This versatile mem­brane cell can be used as a membrane evaluation
device, process development tool or for small-scale
production, while minimizing the amount of mem­brane and sample used. This results in a significant
savings of time and money, enabling you to fully
leverage your investment.

Using Sepa CF II you can easily modify operating
conditions, fluid dynamics and pressure levels to
simulate a broad range of applications. This
enables you to easily determine which GE flat-sheet
membrane is most appropriate for your
intended application.

Features and Benefits

Sepa CF II Membrane Cell system has many fea­tures that make it ideal for use in any reverse os­mosis, nanofiltration, ultrafiltration or microfiltration
crossflow application.

• Accepts any flat sheet membrane.

• Unique piston clamping mechanism. Patented

pneumatic or hydraulic mechanism enables
quick change out of membrane in less than one
minute, and then quickly seals it with uniform
pressure and a leak-proof seal.

• Wide variety of shims and spacers. Optimizes
flow characteristics during filtration, maximizing
membrane efficiency.

• Accommodates pressures to 1000 PSIG (69 bar).
Allows for the simulation of a greater range of
large-scale applications at optimal rates.

• Stainless steel body with Viton (Viton is a regis­tered trademark of DuPont Dow Elastomers)
o-ring. Contributes to flexibility of use by allow­ing almost any type of substance through the
membrane cell.

Typical Applications

Fluid Transfer

Depending on pressure, standard tubing or hose
can be used for connecting cells to vessels. The
connection between the pump and inlet valve on
the cell should be a high-pressure hose. Contact GE

Compatible Flat Sheet Membranes

Accommodates any 7.5 in x 5.5 in (19 cm x 14 cm)
flat sheet membrane for a full 22 in
effective membrane area. (See Figure 3 which
shows assembling the cell membrane.)

GE offers precut and individually wrapped mem­brane inserts in single or assortment packs from
our large selection of reverse osmosis, nanofiltra­tion, and ultrafiltration membranes. Single packs
are available with the microfiltration membranes.
