· Material Diversity: NF membranes can be fabricated from a wide range of materials, including polyamide, cellulose acetate, sulfonated polysulfone, aromatic polyamide composites, and inorganic materials. Some NF membranes feature surfaces coated with polyelectrolytes, giving them a negative charge that enhances the rejection of charged ions.
· Technology Positioning: In its early stage, the NF membrane was often referred to as a "low-pressure RO membrane" or "loose RO membrane." It is recognized today as a novel pressure-driven membrane technology positioned between Reverse Osmosis (RO) and Ultrafiltration (UF).
