Nf Membrane Filter(Nanofiltration membrane) is a membrane filtration-based method that uses nanometer sized through-pores that pass through the membrane. NF membrane have pore sizes from 1-10 nanometers, smaller than that used in microfiltration and ultrafiltration, but just larger than that in reverse osmosis.

NF1 series is a Nf Membrane Filter developed for the field of wastewater, having high removal rate of total organic carbon (TOC) and medium interception rate of inorganic salts. Ultra-low pressure and pollution-resistant technology are developed to improve service life and energy efficiency.
