TMF 3838D1N2

Summary

Product identification

Toray's Microfiltration (TMF-series) membranes are low-pressure spiral-wound elements with a molecular weight cut-off (MWCO) between 200,000–1,000,000 Daltons. They feature a polyvinylidene fluoride (PVDF) asymmetric membrane and are designed as net-wrapped (no tail) elements. These sanitary elements are suitable for dairy and food processing applications, designed to remove residual fat from whey and whey protein concentrate while maximizing whey protein transmission.

Material Specifications

• Feed spacer & element outer wrap: Polypropylene
• Permeate carrier: Proprietary
• Adhesives: Proprietary
• Microfiltration Membrane: Polyvinylidene fluoride (PVDF)

Product Specifications (TMF 3838D1N2)

• Feed spacer thickness: 0.046 in. (1.17 mm)
• Active area: 60 ft² (5.6 m²)
• Application: Whey Defatting
• MWCO: 500k–1,000k Daltons

Other TMF-series models are available for Whey Defatting and Casein Separation with varying active areas and feed spacer thicknesses.

• TMF 'D1' membranes have a MWCO of 500k–1,000k Daltons and are used for whey defatting and whey protein isolate.
• TMF 'D2' membranes have a MWCO of 200k–400k Daltons and are used for casein concentrate and brine clarification.
