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.
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

FRESH TASTING WATER：The Reverse Osmosis Replacement Membrane cleans your water by removing heavy metals, inorganics and volatile organics and other harmful chemicals that produce distasteful and smelly odors.
Application
● Pure water system
● Chemical RO filtration
● Desalination of brackish water
● Food and beverage wastewater
● Power plant boiler make-up water
● Medical reverse osmosis filtration system
Important Information
It is recommended that systems using these elements rinse the elements for 24 hours, prior to first use, to meet NSF/ANSI 58 Standard.
The first full tank of permeate must be discarded. Do not use this initial permeate for drinking water or food preparation.
Keep elements moist at all times after initial wetting.
To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution. Rinse out the preservative before use.
The membrane shows some resistance to short-term attack by chlorine (hypochlorite). Continuous exposure, however, may damage the membrane and should be avoided.
