Tubular Polymer Membranes

VINAFLO classic tubular membranes

VINAFLO classic tubular UF/MF membranes are made by coating PES or PVDF membrane on the internal surface of a rolling-weld porous polyester tube. This membrane was the long research result of our techniques in China.
According to our customers' feedback, its flux and separation performance can be competed with some famous brands in the world.
Tubular membrane modules are designed for separation, concentration and purification of the components of liquid mixtures and waste waters (solutions of high-molecular substances and colloidal solutions, finely divided suspensions, oily wastewater, low-coalescing emulsions). They are perfectly suited for treating solutions containing particles and high viscous solutions or solutions becoming viscous during treatment.

VINAFLO 1" tubular membrane

Developed by ourself, 1 inch tbular membranes are available now!

knitted glass fiber porous tube as supporting layer, PVDF membrane as active separating layer.

Higher strenth, long lifetime, outstanding anti-fouling performance... and low price!!
