NF5 Nanofiltration Membrane Elements
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 membrane elements are among the finest in the industry. With hundreds of thousands of membranes in operation world-wide, we offer these nanofiltration (NF) membrane elements in standard residential and commercial sizes. AMI Membranes are Made in the USA in our ISO 9001:2015 Certified Facilities. Each membrane meets or exceeds our strict performance requirements before shipping. For the past 30 years we have earned a reputation of delivering consistent, high quality which makes AMI Membranes the natural choice for use in water treatment systems.
