1812 Spiral Membrane Bench-Scale Unit
1812 Spiral Membrane Bench-Scale Unit
This type of equipment is used for laboratory (bench-scale) verification separation and filtration operations, filled with 1812 spiral-wound membrane cartridges. It is equipped with an imported high-pressure plunger pump, sanitary BA piping, sanitary valves and other components. It is equipped with an automatic frequency converter to ensure stable working conditions and provide parameter references for later pilot-scale and large-scale models.
It is applied in biopharmaceuticals, biological fermentation, animal and plant extraction, food and beverage, cosmetics and other fields, mainly for material clarification, separation, desalination, purification, refining and other processes.

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