XM Series Submerged PTFE Membrane Cassette
Shuiyi Xflon® series submerged PTFE membrane products are specifically developed for high-pollution industrial wastewater sectors such as those containing oil and solvents. These PTFE hollow fiber membranes feature exceptional chemical stability, resistant to strong acids, strong alkalis, oxidizers, and various chemicals, utilizing Shuiyi’ proprietary hydrophilic modification and anti-fouling technologies to enhance both performance and longevity.
Shuiyi Xflon® PTFE separation membranes are dedicated to solving challenges in high-difficulty industrial wastewater treatment and industrial material separation, aspiring to be a leading brand in industrial separation technology.
Description
- Full fluoropolymer construction ensures high tensile strength with zero filament breakage or delamination
Shuiyi PTFE hollow fiber membranes are made entirely from 100% PTFE material, with inner and outer layers sintered together, preventing delamination. PTFE hollow fiber membranes have high mechanical strength, suitable for harsh environments in membrane
bioreactors, with no fiber breakage and a long service life. - Withstands concentrated acids, strong alkalis, and aggressive oxidizers with extended service life
Shuiyi PTFE hollow fiber membranes exhibit outstanding resistance to strong acids, alkalis, and oxidizers. Even when heavily contaminated, they can be thoroughly restored through chemical cleaning,meeting a 10-year lifespan requirement. - Permanent hydrophilic modification, strong anti-fouling performance
Shuiyi PTFE hollow fiber membranes use proprietary hydrophilic modification technology, making the fibers highly hydrophilic and oleophobic. Flux recovery after cleaning is complete, and continuous operation and high-frequency backwashing do not affect their hydrophilicity. These membranes can be stored, transported, and installed dry. The PTFE material used has the lowest surface tension among solid materials, generally preventing oily substances from lingering on its surface, thus exhibiting strong anti-fouling capabilities. - Hot-melt adhesive automated sheet placement with pulsed aeration technology, engineered for anti-fouling performance and sludge-resistant operation
Shuiyi submerged PTFE hollow fiber membrane modules utilize automated fiber alignment technology, arranging the fibers equidistantly and neatly with uniform gaps. Extensive practical applications have shown its effectiveness in alleviating root clogging issues in membrane assembly.
