NANO9 nanofiltration element with good rejection of hardness and salt

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. The low net driving pressure of the element allows the removal of these compounds at low operating pressures.
