POREX® Tubular Membrane Filter (TMF™)

Superior strength of the patented* Porex Tubular Membrane allows higher operating and backwash pressures for a higher flux and reduced system footprint.


Structural Membrane Tubes are Designed to Perform

The patented* Porex Tubular Membrane Filters are designed to fit new and existing tubular membrane systems. In operation, a fluid, such as chemically pre-treated wastewater, flows through the tubular modules at high velocity, sufficient to maintain turbulent flow. At typical operating pressures of 20–80 psi, clean fluid is forced through the pores of the PVDF membrane, while suspended particulates remain in the retentate stream. The turbulent flow of the retentate stream prevents the build-up of particles on the inner surface of the tube, providing high flux and prolonged filter life. This turbulent cross-flow performance and large bore tubular design may eliminate the need for prefiltration and should routinely handle high solids levels up to 5% by weight. * US 7674517
