Summary

POREX® TMF 1.05-Tubular Membrane Filter (TMF) Modules

POREX TMF cross-flow tubular membrane modules are designed for optimal high solids separation at high flux rates. They feature unique, structural membrane tubes with superior strength, allowing for higher operating and backwash pressures, improved solids removal efficiency, higher flux, and a reduced system footprint. The structural composite membrane typically consists of a PVDF membrane bonded to a PVDF substrate or anchored to a PE substrate.

Product Features

• Consistent, reliable solid/liquid separations and long service life.
• Unique support with PVDF membrane offers high performance 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 for optimized support and enhanced membrane durability.
• Available in multiple tube quantities and diameters for increased surface area and flux.
