Summary

POREX® TMF 5-Tubular Membrane Filter (TMF) Modules

Porex TMF cross-flow tubular membrane modules feature unique, structural membrane tubes designed for high solids separation at high flux rates. The superior strength of the membrane/substrate composite allows higher operating and backwash pressures, leading to increased solids removal efficiency, higher flux, and a reduced system footprint. The structural composite membrane uses PVDF membrane bonded to a PVDF substrate or anchored to a PE substrate.

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 provides 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
