Fabrication of Nano Based Water Filters

Project Title

Fabrication of Nano Based Water Filters

Project Area of Specialization Biomedical EngineeringProject Summary

The main objective of this project is to invent water filters through nanotechnology by synthesizing Cobalt doped Zinc Oxide Reduced Graphene Oxide Nanoparticles and monitoring its applications in water purification. A typical water filter consists of 3 chambers:

1st chamber collects sediments through a filter

2nd chamber adsorbs heavy metals to its surface.

3rd chamber has ultraviolet light that contribute in killing microbes in a very small range.

The main idea of our project is to compact these three chambers into one specific chamber that is more efficient and performs much better activity than the traditional water filters.

For that, we first need to synthesize Reduced Graphene Oxide through graphite flakes. Once Reduced Graphene Oxide is synthesized then we are going to co-dope it with Cobalt/Zinc Oxide Nanoparticles together known as Cobalt Doped Zinc Oxide Reduced Graphene Oxide Nanoparticles.

The functions of Cobalt Doped Zinc Oxide Reduced Graphene Oxide in water purification are:

i)                    Reduced graphene oxide can adsorb heavy metals on its surface

ii)                   Cobalt Doped Zinc oxide have photocatalytic function and are activated through normal visible light and kills microbes in a long range.

So, the idea is that by synthesizing Cobalt doped Zinc Oxide Reduced Graphene Oxide Nanoparticles we can compact these three chambers present in a typical water filter into one specific chamber where Reduced Graphene Oxide will adsorb heavy metal on its surface and Cobalt doped Zinc Oxide will not only kill microbes in a long range but also will be activated through normal LED bulbs. Thus this project is playing an effective role in water purification that too in an affordable range since we are not only merging 3 typical water filter chambers into one but also using normal LED lights in replacement of UV-light for making drinking water free from microbes and heavy metals.

Project Objectives

Using novel techniques for Water Purification in a cost efficient way and brining cheap water filters in the market that eradicate water contaminants rigorously in a much better way than the traditional water filters.

Project Implementation Method

Once Cobalt Doped Zinc Oxide Reduced Graphene Oxide is synthesized then we will test its efficiency on the contaminated water, polluted with microorganisms and heavy metals. The main focus of this procedure is 'tap water'. Impure tap water is global issue having adverse effects on health, most often leads to severe disease which ultimately results in death. In this approach, the tap water will be screened to check if any impurity is present in the water. In case of the presence of any impurity, the water will be treated with the aforementioned technique, and screened again to confirm the purity of water.

Benefits of the Project

Fabrication of water filters that eliminate contaminants from drinking water in a more efficient and cheaper way, thus making it fit for human consumption that too in an affordable range.

Technical Details of Final Deliverable

As we know, that the water crisis is receiving close reviews for the past few years, keeping in view its destructive effect on an individual health. Therefore, our approach is serviceable enough to cope-with this problem. Also, this proposal involves the removal of heavy metals from water which could be seriously harmful for one's health. The most contemporary application of this approach is the use of 'LED Lights' instead of UV light which has the potential to eliminate the microorgarmins present in the water in a far away range.
