Wastewater treatment using Nanotechnology
Topic: : Study of waste water treatment technology with the aid of Nanotechnology/Biotechnology

Project Summary : Nanotechnology is a broad field and has the potential to change the traditional waste water treatment paradigm. Nanomaterials have many unique properties that can enable novel technologies for contaminant removal, sensing and monitoring, microbial control and resource recovery. They have properties like high surface area, high reactivity and high catalytic properties. Nanomaterials are also very diverse for e.g. Nanotubes, nanoparticles, nanowires, dendrimers, zeolites etc.Carbon nanomaterials like Carbon nanotube have high conductivity, mechanical strength and surface areas thus making them as good candidates for biosensors for detection of pesticides, metal ions and other environmental pollutants. Dye nanoparticle-coated test strips can be used for detection of inorganic ions in the wastewater.Waste water treatment can also be done though dendrimer enhanced filtration. Dendrimers are highly branched globular nanoparticles with controlled size and architecture. They can easily serve as nanoscale reactors and can bind as well as deactivate viruses and bacteria. Clay mineral nanotubes can be used for waste water treatment as well. They are also environmentally friendly. However, disadvantages of using nanomaterials for wastewater treatment include difficulty in separation from the solution thus leading

Objectives of the study
a)To find/synthesise/develop and characterize an optimal nanomaterial with minimal drawbacks for wastewater treatment.
b)To use the nanomaterials for removal for specific pollutants like heavy metal, inorganic ions.
c)To develop nanocomposites with enhanced properties to treat problems like biofouling.
d)To develop membranes with immobilised nanoparticles for enhanced filtration of wastewater.
e)To minimise any waste generated by nanodevices or during the fabrication of nanomaterials.
