Product Description

UltraClean UC NF280 series nanofiltration membrane elements have ultra-high flux, can highly remove TOC and THM (trihaloalkane) precursors, while divalent salts passed moderately, other salts passed moderately or to a higher degree. It is to remove organic matter in surface water and groundwater and moderately soften, concentrate, separate or purify ideal membrane element for inorganic salts, organics, natural medicines and fermentation broths. NF280-400/34 elements have large membrane area and high water yield, providing a wide range of water treatment and concentration and separation application options for industrial production. It is suitable for systems that remove TOC, THM precursors and salts from water under ultra-low pressure conditions with low operating energy consumption, as well as in material separation, municipal and industrial water treatment.


Product  Highlights

1.Ultra-high throughput
2.High removal of TOC and THM (trihaloalkane) precursors
3.Ultra-low operating pressure can effectively reduce the operating energy consumption of membrane system3.Stable chemical properties, strong anti-pollution
