Ultrafiltration on steroids
SpinTek’s advanced Hollow Fiber (HF) Membrane
technology is a simple, powerful ultrafiltration
solution. SpinTek’s HF membranes provide a high
surface area that allows you to create compact
filtration systems with space saving advantages and
higher filtration rates.

Fiber Diameters
The standard diameters are 1.2 mm OD, 0.8 mm
OD (available October 2007) and 0.6 mm OD
(available October 2007). Other sizes are available
based upon custom tooling for a specific size. Lead
time is typically 12 weeks for a custom size using
current formulas.

Formulations
SpinTek is currently in production of hollow fiber
membranes for a variety of applications including
use in the Sparkle drinking water system. SpinTek
hollow fiber membranes are currently available in
Polysulfone and Polyethersulfone. Both polymers
are available with standard 50,000 NMWC or
100,000 NMWC cutoffs, though smaller or larger
cutoffs can be formulated depending upon the
application.

Fiber Lengths and Configurations:
Hollow fibers are available as continuous rolls or
can be precut to length. They are also available wet
or fully dry for potting. The maximum straight
length of cut fibers with no bends from manufacturing is:
• 1.2 mm OD is available up to 72" (1829 mm)
• 0.8 mm OD is available up to 72" (1829 mm)
• 0.6 mm OD is available up to 60" (1524 mm)

Hollow fiber membranes can be
assembled into bundles

Hollow Fiber
KEY BENEFITS
• Uses cost-effective, high-performance Membrane Ultrafiltration
Technology
• Low fouling system suffers little degradation of performance
between maintenance periods over months of use
• Human powered. A complete flexible system that doesn’t rely
on dubious electric delivery in outlying developing regions. Can
be converted to solar or animal power
• Little maintenance. This is an important factor in remote
locations with limited technical support
• Combination of technologies. HF, carbon filter, and ion
exchange filter eliminate virtually all contaminants while
providing fresh drinking water source from 150 to 200 gallons
per hour
• Easy to transport, install and maintain
