TMF 1.1

Summary

Product identification

• POREX® TMF 1.1-Tubular Membrane Filter (TMF) Modules
• Optimal high solids separation at high flux rates.
• Cross-flow tubular membrane modules contain Porex’s unique, structural membrane tubes.
• The superior strength of the membrane/substrate composite allows higher operating and backwash pressures for superior solids removal efficiency, higher flux, and reduced system footprint.
• The structural composite membrane features PVDF membrane bonded to PVDF substrate or anchored to PE substrate.

TMF Series Features

• Consistent, reliable solid/liquid separations and long service life.
• Unique support with PVDF membrane offers high performance tubular membrane with superior operating characteristics.
• Sintered PVDF substrate with PVDF membrane offers high temperature and improved chemical compatibility (pH range of 0–14).
• PVDF/PVDF composite option offers 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 provides an optimized support structure for tubular membranes and enhanced membrane durability.
• Available in multiple tube quantities and diameters for increased surface area and flux.
