Hollow Fiber Nanofiltration MembraneN90-3040
With breakthroughs in membrane materials and element structure,
Ochemate Advanced Material Technologies Co. Offers NÜF® N90
membrane elements with hollow fiber structure for industrial and municipal application.
NÜF® N90 has high
permeability under low
pressure and provides unique comprehensive advantages
for industrial and municipal users.
Hollow fiber nanofiltration
membrane NÜF® N90 element can effectively remove impurities from
water in commercial applications:
harmful substances such as
colloids, bacteria, viruses, and organic matter retain beneficial minerals and
trace elements. It can be widely used for drinking water in commercial office
buildings, canteens and catering institutions, hotels and clubs, hospitals and
schools, airports and stations, and other public places. It can achieve a
balance between safety and health in drinking water purification technology -
creating "better drinking water, healthier membranes".
Feature
• High hardness removal, high
efficient toxic metals removal such as copper, cadmium, chromium, lead,
mercury, antimony and arsenic.
• High small organic molecule
removal (such as antibiotics, endocrine disruptor, etc.) and reduce COD in
water.
• High removal rate for
monovalent salt.
NÜF® N90 element
has the typical characteristics of all NÜF® product series:
• Unique hollow fiber structure.
• high anti-fouling capacity
• Low operating pressure,
high permeate flux.
Product Types
TPFP integrated film
forming technology & modified polyamide as base material.

• At the first use, it is suggested that rinse the protective agent from NÜF® membrane through connecting water for one hour. Please discharge the permeate water from this one hour. • Membrane elements should always be kept moist after initial use. |
|||||||||||||||||||||||||||||||||||||||
• Membrane elements have a short-term resistance to free chlorine and other oxidants. Long-term contact may lead to damage of membrane fibers. Continuous exposure of membrane components to free chlorine or other oxidants should be avoided. | |||||||||||||||||||||||||||||||||||||||
• Back pressure on the permeate side should be avoided at all times. |
