Microfiltration Membrane

Sanitary element for dairy and food processing
Toray's Microfiltration (TMF-series) membrane separation is a low-pressure process with amolecular weight cut-off (MWCO) of between 200,000–1,000,000 Daltons.
TMF-series models are net-wrapped (no tail) spiral-wound elements incorporating a
polyvinylidene fluoride (PVDF) asymmetric membrane. They are designed to remove residual
fat from whey and whey protein concentrate and maximizing whey protein transmission.
