Ultrafiltration membrane is a porous membrane with super "screening" separation function. Its pore size is only a few nanometers to tens of nanometers, which is only 1‰ of a hair! Applying appropriate pressure on one side of the membrane can screen out solute molecules larger than the pore size to separate particles with a molecular weight greater than 500 Daltons and a particle size greater than 2 to 20 nanometers.
Introduction
Ultrafiltration membrane is a porous membrane with super "screening" separation function. Its pore size is only a few nanometers to tens of nanometers, which is only 1‰ of a hair! Applying appropriate pressure on one side of the membrane can screen out solute molecules larger than the pore size to separate particles with a molecular weight greater than 500 Daltons and a particle size greater than 2 to 20 nanometers.
The New Era of Molecular Separation
Modern industrial challenges demand more than traditional filtration can provide. Where conventional UF membranes offer static performance, our dynamically responsive filtration platforms adapt to changing feed conditions while maintaining critical separation thresholds. This technological leap enables:
1. Adaptive pore structures that tighten under high contaminant loads
2. Self-diagnosing membrane surfaces that signal fouling before it impacts performance
3. Regenerative polymer matrices that recover from chemical exposure
These capabilities stem from our multi-disciplinary membrane science program, combining materials engineering, nanotechnology, and industrial IoT to create the most advanced filtration media available today.

Q&A
Q: What are "virus-retentive" UF membranes?
A: Membranes with ≤20 nm pores (NFR/Nano Filtration Range) to remove small viruses (e.g., parvovirus) in biopharma/water treatment.
Q: How does UF enhance MBR (Membrane Bioreactor) efficiency?
A: Replaces clarifiers, allowing higher sludge concentrations and superior effluent quality (turbidity <0.2 NTU).
Q: Is UF suitable for oily wastewater treatment?
A: Yes, but requires pre-treatment (e.g., DAF or coalescers) to avoid irreversible membrane fouling by emulsified oils.
