Nanofiltration (NF) is a state-of-the-art membrane-based separation process renowned for its ability to effectively treat wastewater, effluents, and other challenging water sources. NF technology delivers high-performance separation by targeting multivalent ions, pathogens, suspended solids, and larger colloids. Its versatility and efficiency make it an essential component in modern water and effluent treatment systems.
Key Features of NF Technology
NF membranes are engineered with a nominal pore size of approximately 0.001 microns and a molecular weight cut-off (MWCO) range of 1,000 to 100,000 daltons. These membranes demand higher operational pressures compared to Microfiltration (MF) or Ultrafiltration (UF) to achieve optimal filtration and deliver clear, high-quality water.
Operational Pressure: NF systems typically operate at pressures between 6–15 barg (600–1500 kPa), ensuring the effective removal of contaminants while maintaining efficiency.
Water Softening: NF technology excels in water softening by removing hardness, making it a reliable pretreatment step for Reverse Osmosis (RO) systems.
Advantages of Nanofiltration (NF)
NF membranes strike a balance between separation precision and operational efficiency, making them ideal for applications where fine filtration and resource recovery are critical.
