QILEE Advanced Ultrafiltration Membrane: Precision Separation Technology for Diverse Water Sources

QILEE ultrafiltration membranes represent a breakthrough in membrane separation science, employing optimized polymeric formulations and structural engineering to achieve unparalleled filtration performance. Our hollow fiber membranes feature a graded pore structure with surface charge modification, creating not just physical but also electrochemical barriers against contaminants. The membranes operate on the principle of size-exclusion chromatography at macroscopic scale, where particles, colloids, and macromolecules are separated based on hydrodynamic radius rather than molecular weight alone. This approach enables exceptional recovery rates even with challenging feed waters containing high organic loads or variable turbidity.
The membrane's unique asymmetric structure combines a tight separation layer with a highly porous support matrix, minimizing hydraulic resistance while maintaining rejection capabilities. Our proprietary manufacturing process ensures consistent pore distribution within 0.03-0.05μm range, with coefficient of variation below 5% - a critical factor for predictable scaling and system design.
