Sterlitech Sepa CF II Membrane Cell System Benefits and Features
• Accepts Any Flat Sheet Membrane:
Maximum flexibility ensures the most efficient and cost effective
membrane is chosen for future scale-up or small scale production.
Sepa CF II Membrane Cell System accommodates any 19 cm x 14 cm (7.5
in x 5.5 in) flat sheet membrane for a full 140 square cm (22 square
inches) of effective membrane area. For convenience, Sterlitech
offers precut and individually wrapped membrane inserts in single
packs from our large selection of reverse osmosis (RO), Nanofiltration
(NF), ultrafiltration (UF), and microfiltration (MF) membranes.
Some assortment packs are available.
• Unique Piston Clamping Mechanism: Membrane change
out takes less than one minute. The unique patented mechanism quickly
seals the cell and provides uniform pressure to assure a perfect
seal – a significant improvement over other multiple bolt
lab scale units with inherent, uneven torque and leak problems.
Sepa CF II Membrane Cell System’s versatile hydraulic mechanism
utilizes a hand pump for its pressure sources. The pressure relief
valve is set to 1,000 psi. We strongly recommend the hand pump as
a safety feature.
• Compatible With Wide Range of Feed Flow Fluid Pumps:
Special pumps are not required. Many standard lab scale pumps can
provide the wide range of pressure and flow that the Sepa CF II
Membrane Cell System is capable of using. Any pump operating less
then 2 gpm should work with the system. We recommend a piston driven
diaphragm pump.
• Concentrate Flow Control Valve: Stainless steel concentrate
flow control valve gives users accurate control of pressure and
flow over the membrane surface. This easy-to-use valve is mounted
on the concentrate outlet of the cell and is easily removed for
inspection and cleaning.
• Stainless Steel Cell With Viton®* O-Ring: The
34 mil or 75 mil stainless steel cell body contributes to flexibility
of use by allowing almost any type of substance through the membrane
cell.
• Wide Variety of Feed Spacers and Permeate Carriers:
User selects from a variety of spacer configurations, identical
to those used in large-scale sepralators, to help optimize flow
characteristics for the particular solution being processed. Mesh
or tubular feed spacers (along with the membrane and the permeate
carrier) are loaded in the stainless steel cell body to simulate
the actual flow of characteristics of a wide variety of available
spiral-wound and tubular membrane elements. These spacers, in conjunction
with the concentrate flow control valve, allow the user to test
laminar or turbulent flow conditions.
• Wide Variety of Shims and Spacers: Optimizes flow
characteristics during filtration, maximizing membrane efficiency.
Placing the correct shim and spacer to fill the cell cavity when
used with the membrane and permeate carrier may optimize flow conditions.
Suggested 1-2 mil of space should remain after the complementary
shim and spacer are selected. We strongly recommend when using thinner
feed spacers the use of the complementary shim to allow the system
to properly work.
• Multiple Ports for Instrumentation: Pressure gauges,
flow meters, pH monitors, etc., are easily connected to the cell
to monitor important process parameters. Pressure gauges indicating
piston sealing pressure and concentrate fluid pressure are included
as standard features with the system.
• Laminar or Turbulent Flow: Shear sensitive feed solutions
can be processed in laminar flow mode while less sensitive solutions
can be processed in turbulent flow mode to lessen membrane fouling.
Sepa CF II Membrane Cell System is versatile enough to operate in
either flow mode.
• Pressures to 1,000 psi (69 bar): Separations can be
performed at optimum rates, thus saving time and money. Permeate
flow rate is approximately proportional to driving pressure. Therefore,
higher pressure means higher permeate flow and faster concentrations.
Lower pressures can be used to satisfy special membrane or solution
requirements.
