10K Ultrafiltration Membrane
Sanitary element for dairy and food processing

Toray's 10K Ultrafiltration (TUF-series) membranes have a molecular weight cut-off (MWCO)of 10,000 Daltons. TUF-series models are net-wrapped (no tail), spiral-wound elements
using a hydrophilic polyethersulfone (PES) asymmetric membrane specifically developed
to retain milk and whey proteins, and maximize productivity.

Applications

Toray's TUF-series 10K membranes offer high flux and protein
retention ideal for whey processing at all concentrations andmilk protein concentration (MPC) applications. Toray's TUFseries 10K HR (High-Rejection) membranes yield high protein
retention for high concentration end of whey and whey protein
isolate (WPI) plants.
