SS Series by SpinTek

Tubular Membrane Systems

SpinTek’s Membrane Products Group
specializes in solutions for waste and process
streams formerly considered untreatable.

High Solids, Low Fouling
The SpinTek SS series of tubular membrane systems
are designed for small to medium flow rates with feed
streams that are high in suspended solids. The SS
tubular membranes have 1.0" diameter feed channels
to allow large solids to pass through the system
without plugging the membranes. Perfect for oil/
water separation applications including metal
working fluids and oily emulsions, the SS system uses
high cross flow velocity developed by a recirculation
pump to reduce membrane fouling. The SS system is
available in standard sizes suitable for many industrial
applications. Custom systems can be designed for
larger applications of where the solution being
processed requires special materials of construction.

Membrane Composition
The SS series can use a wide variety of standard
membranes. Membranes available are manufactured
of polyvinylidene fluoride (PVDF), polysulfone
(PS), and polyether sulfone (PES). Membrane pore
sizes range from 5,000 NMWC (nominal molecular

weight cutoff) up to 100,000 NMWC.

Membrane Housing
Standard membrane housings contain 1" diameter
tube and are constructed of PVC with a maximum
operating pressure of 70 psig. PVC maximum
pressure rating is 120F. CPVC can be used where
operating conditions are at a maximum pressure of
160F and 90 PSIG. Alternate housings are available
constructed of 304 SS.
Membrane Cleaning
The membrane surface can be mechanically cleaned
by passing special sponge balls through the tubes. The
flow can be reversed for multiple passes if needed.
Controls and Instrumentation
The SpinTek SS systems are fully instrumented and
automated for production use. The SS controller is
simple to operate and has lights, switches and enclosure rated NEMA 12. alternate NEMA ratings are
available. Standard instrumentation includes feed,
recycle, and concentrate pressure gauges and flow
