Nanotechnology in water treatment

How can nanotechnology be used to purify water?

Water purification using nanotechnology exploits nanoscopic materials such as carbon nanotubes and alumina fibers for nanofiltration. For instance, carbon nanotube membranes can remove almost all kinds of water contaminants including turbidity, oil, bacteria, viruses and organic contaminants.

What is Nano water filtration?

Nanofiltration (NF) is a relatively recent membrane filtration process used most often with low total dissolved solids water such as surface water and fresh groundwater, with the purpose of softening (polyvalent cation removal) and removal of disinfection by-product precursors such as natural organic matter and

Should nanotechnology be used for sewage or industrial wastewater treatment?

In the aspect of sewage treatment , nanotechnology has shown a high degree of superiority over conventional methods. Nanotechnology has a good effect on organic waste, especially organic matter such as chlorides, which cannot be used in conventional methods.
