Membrane Filtration Precision Comparison
| Membrane Type | Retention Pore Size Range | Retained Substances | Core Process Function | Typical Application Scenarios |
|---|---|---|---|---|
| Microfiltration (MF) | 0.1-10 μm | Suspended solids, colloids, bacteria, impurity particles | Coarse filtration, pre-clarification | Raw material pretreatment, beverage coarse filtration, water treatment pre-filtration |
| Ultrafiltration (UF) | 0.001-0.1 μm (1-100 nm) | Proteins, polysaccharides, macromolecular colloids, viruses | Purification, separation, decolorization | Biopharmaceuticals, animal/plant extracts, fermentation broth clarification |
| Nanofiltration (NF) | 0.0001-0.001 μm (0.1-1 nm) | Divalent salts, small-molecule pigments, polysaccharides | Decolorization, mild desalination, concentration | Juice concentration, TCM purification, reclaimed water softening |
| Reverse Osmosis (RO) | < 0.0001 μm (< 0.1 nm) | Inorganic salts, small-molecule organics, heavy metals | Desalination, pure water production, material concentration | Pure water treatment, environmental wastewater, food concentration and desalination |
