TMF 37

Summary

Product identification

POREX® TMF 37-Tubular Membrane Filter (TMF) Modules are designed for optimal high solids separation at high flux rates, utilizing unique, structural membrane tubes for superior strength and higher operating/backwash pressures.

Key Features:

• Consistent, reliable solid/liquid separations and long service life.
• Unique support with PVDF membrane for high performance.
• Sintered PVDF substrate with PVDF membrane offers high temperature and improved chemical compatibility (pH range of 0–14).
• PVDF/PVDF composite option provides increased abrasion resistance and enhanced membrane durability.
• Three distinct membrane pore sizes available on two different substrate options.
• Uniform, thermally-bonded omni-directional substrate pore structure for optimized support and enhanced membrane durability.
• Available in multiple tube quantities and diameters for increased surface area and flux.
