Nanotechnology in Remediation (Environmental clean up)

Removal of pollutants and contaminants from environment as nontoxic

substances

In remediation technology mainly use: living organism (i.e. (bioremediation)

microbes, fungi, bacteria, plants etc.), chemical substance (i.e. metals NPs,

polymers) and many nano scale materials (i.e. metal oxides, carbon nanotubes,

nanoscale zeolites, fibres etc.)

Use of nano devices to enhance microbial activity to remove pollutants

Nano based sequence bioreactor has been designed and developed by Prof.

M.H. Fulekar in 2009 for the bioremediation of hazardous waste with the

special reference to dye stuff effluents.

In the first reactor the physicochemical and microbial characterized effluents

will be taken where in TiO2 nano based semiconductor will be used under the

influence of UV radiation for the oxidation/reduction and chemical degradation

of dye stuff effluents.

Nano biosensors will be used to observe rate of chemical degradation of the

hazardous compound present in dye stuff effluents.

First reactor was connected to second bioreactor through the peristaltic pump

where mycorrhizal soil amended with Gold NPs/sand/gravel will be arranged

one below the other on perforated plates at the bottom inside the bioreactor for

trickling the contaminants.

Page 13: Sustainable nano based technology ppt

This technology will be useful to the Petrochemical industry and Chemical

industry which generates the waste containing compounds such as phenol

Provide and fundamentally restructure the technologies currently used in

environmental detection, sensing, remediation and pollution removal

Eco-friendly, No toxic martials formed

Sustainable for Environment, Social and Economical

I don’t want to protect the environment

I want to create a environment where the environment doesn't need protecting
