Nanofiltration (NF) Membrane Elements
AMI Nanofiltration Membrane Elements (NF Membranes)
- AMI® NF5 spiral wound nanofiltration elements are ideal for removing a high percentage of TOC and THM precursors with medium to high salt passage and medium hardness passage. NF5 membrane elements are an ideal choice for surface water and groundwater where good organic removal is desired with partial softening.
- AMI® NF9 spiral wound nanofiltration membranes provide high productivity performance while removing a high percentage of salts, nitrate, iron and organic compounds such as pesticides, herbicides and THM precursors. The low net driving pressure of the NF9 membrane allows the removal of these compounds at low operating pressures.
