Nano-Filtration is a thin film with a pore size between reverse osmosis membrane and ultrafiltration membrane.The water flux is higher than that of commercial NF membrane by 30%~70%, and the energy consumption is reduced by 30~50%. With surface charge structure, it can be used to selective separation. We serves customers with adjusting the membrane according to different uses. 

Applications
Water treatment, softening, decolorization, concentration, selective separation, and etc.

Features

• Removal of 99% or more of metal ions or small organic molecules such as sodium, calcium, magnesium, etc.
• It can save more than 35-55% of high-concentration water treatment costs such as industrial wastewater and domestic sewage.
