Nano-filtration System

Short Description:

Nano-filtration is a new type of molecular-level separation technology that falls between traditional separation ranges of ultra-filtration and reverse osmosis. The characteristic ofnano-filtration is that it can retain small molecular weight organic substances that pass through ultra-filtration membranes, while also dialyzing inorganic salts that are retained byreverse osmosis membranes, allowing for simultaneous "concentration" and desalination.When using nano-filtration to ｒｅｐｌａｃｅ reverse osmosis, the "concentration" process is more efficient and faster, achieving a higher "concentration" multiple. Nano-filtration (NF) membranes mainly remove solute ions with a diameter of about 1nm, retain molecules with a molecular weight of around 200 or more, and have an exclusion capacity of 90% to 99%....
