Synder Filtration offers the widest range of
ultrafiltration membranes available to provide
maximum flexibility in solving unique process
challenges. Available in both spiral wound and
flat sheet membrane configurations, Synder can
customize ultrafiltration membranes and membrane
systems to meet the specific application goals of
our customers.

Ultrafiltration membranes are capable of
separating larger materials such as colloids,
particulates, fats, bacteria, and proteins, while
allowing sugars, and other low molecular weight
molecules to pass through the membrane.

With a pore size range between 0.01 to 0.1µm,
ultrafiltration membrane pore sizes fall between
that of nanofiltration and microfiltration. UF
membranes typically operate between 50 120 PSI
(3.4 8.3 bar) and are dependent on
transmembrane pressure to drive the separation
process. Other polymeric ultrafiltration membrane
characteristics include robust chemical and
temperature resistance, and low fouling
tendencies if proper pretreatment is employed.

Cross Flow Ultrafiltration (also known as
Tangential Flow Ultrafiltration) is a separation
process where the feed stream is in parallel to
the membrane surface, which helps to control the
formation of the gel layer, greatly improving
flux stability and membrane life vs.
perpendicular flow systems. As opposed to
conventional filtration which causes a quick
build-up of solids onto the membrane surface,
cross flow filtration increases the passage of
permeate through the membrane and overall flux
efficiency.

Both sanitary and industrial ultrafiltration
membranes are comprised of a semi-permeable,
polymeric membrane layer cast onto a uniform
substrate, or backing material. Synder Filtration
employs phase inversion to extra solvents out of
the liquid polymer dope that has been cast onto
the backing material. As the solvents are
extracted, the polymer solidifies forming an
asymmetric pore structure, which is ideal for
controlling rejection at the surface, while
promoting maximum throughput of permeate.
