Summary
Product identification
The NANO9 is an ultra-low energy, excellent ion selective nanofiltration element. Oltremare NANO9 nanofiltration elements are high productivity elements designed to remove a high percentage of salts, nitrates, and organic like pesticides. They are ideal when a good rejection of hardness and salt is required.
Membrane Characteristics
- Membrane: NF
- Membrane Type: Polyamide
- Stabilized Salt Rejection (%):

|---|---|---|---|---|---|
| Oltremare NANO9 - 2540 | 1.8 (4) | 1016 (40) | 61 (2.4) | 19.1 (0.75) | Male |
| Oltremare NANO9 - 4021 | 1.8 (4) | 533.4 (21) | 100.3 (3.95) | 19.1 (0.75) | Male |
| Oltremare NANO9 - 4040 | 3.6 (8) | 1016 (40) | 100.3 (3.95) | 19.1 (0.75) | Male |
- For male elements, "C" is the outer diameter.
- Male elements have a protruding permeate tube. Dimension “D” for this tube is 30.5 mm (1.2 in) for modules 2540 and 4021, and 26.7 mm (1.05 in) for the 4040 module.
Important Information
- Start-up: It is recommended to flush elements for 30 minutes at low pressure and discard permeate during the flush prior to operation.
- Cleaning: Oltremare membrane elements must be cleaned periodically to ensure proper operation and to prevent membrane damage.
- Storage: Oltremare membrane elements must be stored appropriately to ensure proper operation and to prevent membrane damage.
