Product water

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.

Mechanical / hydraulic

The following physical dimensions are specified for the Oltremare NANO9 - 4040 model:

• Element Weight (e): 16.4 kg (36 lb)
• Dim. A: 1016 mm (40 inches)
• Dim. B: 200 mm (7.89 inches)
• Dim. C (f): 28.6 mm (1.125 inches) (inner diameter for female elements)
• Permeate Tube (g): Female

Important Notes

• Start-up: It is recommended to flush elements for 30 minutes at low pressure and discard permeate during the flush prior to operation. Refer to the Element Start-Up Guide for further information.
• Cleaning: Elements must be cleaned periodically. Refer to the Membrane Cleaning Guide for details.
• Storage: Elements must be stored appropriately. Refer to the Element Storage Guides for details.
