Advanced Nanofiltration (NF) Membranes Designed for Complex Filtration Needs
IonClear nanofiltration membranes are engineered for precision separation, efficient performance, and long-term durability in complex industrial water treatment processes. With molecular weight cut-offs (MWCO) ranging from 90–500 Da, IonClear NF membranes enable selective ion retention, organic molecule separation, and monovalent salt permeation at operating pressures significantly lower than reverse osmosis (RO).
Designed to meet the needs of sectors such as biopharma, food and beverage, and industrial wastewater treatment, our nanofiltration membrane technology delivers:
- Efficient operation at 100–150 psi
- Flux rates of 15–20 LMH
- High rejection of COD, TOC, and divalent salts
- Broad pH tolerance and chemical resistance
Whether you’re targeting ZLD pre-concentration, water softening, or specialty separations, IonClear NF membranes offer reliable performance, customizable selectivity, and long-term operating value.

Engineered Nanofiltration Membranes for Targeted Separation

IonClear NF membranes are built for high-selectivity separations that require precision control over ionic and organic passage. With optimized polyamide composite construction and a low-pressure operation profile, these membranes reduce energy costs by up to 40% compared to conventional RO systems, while maintaining stable performance under varying feed conditions.
Available in 8″ and 4″ element formats, IonClear nanofiltration membranes are compatible with most industrial systems and can be tailored to your specific process chemistry and separation goals.
