The morphology, hydrophobicity of three commercial membranes on long-term performance.
| Commercial membranes | Hydrophobicity/hydrophilicity | Roughness | Flux decline |
|---|---|---|---|
| Polysulphone (PSf) | Hydrophobicity | More rough | Largest |
| Polyethersulphone (PES) | Hydrophobicity | Smoother | Less large |
| Regenerated cellulose (RC) | Hydrophilicity | Similar roughness to PSf | Smaller |
