Fact Sheet

SEPA* CF II
Membrane Cell System
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.
•
•

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.
