6. 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

Improvement in bioreactor by nanotechnology
 CNTs-adsorbed toxic
gases
 Nano fibres layers
 Nano catalyst :
MnO removes volatile
organic compounds from
industrial smokestacks
 Adsorbents : Active
carbon fibres, zeolite,
silica.

10.  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.

12. CONCLUSION
12

13.  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
