NANO7 nanofiltration membrane with good rejection of TOC and organics, and medium to high salt passage
Oltremare NANO7 nanofiltration elements are designed to remove a high percentage of TOC and organics with a medium to high salt passage and medium hardness passage. It is an ideal element when a good removal of organics is required, with a partial softening in order to maintain a minimum level of hardness. The low net driving pressure of the element allows the removal of these compounds at low operating pressures.
