Nano 7 8040

Summary

Product identification

The NANO7 is an ultra-low energy, excellent ion selective nanofiltration element. 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 ideal when good removal of organics is required, with partial softening to maintain a minimum level of hardness.
