Abstract:
Nanoparticles have a great potential to be used in waste water treatment. Its
unique characteristic of having high surface area can be used efficiently for
removing toxic metal ions, disease causing microbes, organic and inorganic
solutes from water. Various classes of nanomaterials are also proved to be
efficient for water treatment like metal-containing nanoparticles, carbonaceous
nanomaterials, zeolites and dendrimers. The paper reviews recent advances on
different nanomaterials (nanostructured catalytic membranes, nanosorbents,
nanocatalysts, bioactive nanoparticles, biomimetic membrane and molecularly
imprinted polymers (MIPs)) with their application in waste water treatment.
Nanotechnology has lead to various efficient ways for treatment of waste water
in a more precise and accurate way on both small and large scale.
Since
water treatment by using nanoparticles has high technology demand, its usage
cost should be managed according to existing competition in market (Crane et
al., 2012)1. There are various recent advances on different nanomaterials
(nanostructured catalytic membranes, nanosorbents, nanocatalysts, bioactive
nanoparticles, biomimetic membrane and molecularly imprinted polymers (MIPs))
for removing toxic metal ions, disease causing microbes, organic and inorganic
solutes from water.
