Specialty — Tubular Filtration
SP-TB Series — Organic Tubular Membranes
PTFE, PVDF and PES tubular membranes, 10 kDa to 0.2 µm
Product description
Organic tubular membranes are high-performance precision filtration membranes, available as sintered tubular membranes and non-woven tubular membranes, in PVDF, PES, PTFE and other materials. Separation precision ranges from 10 kDa to 0.2 μm.
Membrane tube inner diameters are 6, 8 and 10 mm for non-woven tubular membranes and 8, 12.7 and 25.4 mm for sintered tubular membranes. Standard module sizes are 4-inch, 6-inch and 8-inch, with non-standard materials and sizes available on request.
Working principle: the tubular structure allows liquid to flow in laminar or micro-turbulent regimes inside the membrane tubes, enabling separation based on membrane pore size. Sintered tubular membranes support backwashing to maintain stable flux, while non-woven tubular membranes handle high-solid and high-viscosity systems. PTFE tubing allows aggressive chemical cleaning to restore flux for long-term stable operation.

Performance figures are nominal values obtained under the standard test conditions stated with each table. Actual performance varies with feedwater chemistry, pretreatment, flux, recovery, temperature, pressure and operating practice. Individual element flow may vary from the nominal value. Specifications are subject to change without notice — request the current datasheet before specifying.
