New Delhi: IIT Kanpur recently made a path-breaking development in the treatment of wastewater. They have formulated a novel nano adsorbent that will aid in the selective elimination of metal and antibiotic-resistant bacteria from polluted water with a rapid method to synthesise.
The research team was led by Dr Niraj Sinha and Dr Archana Raichur, Department of Mechanical Science at IIT Kanpur. In recent years, there has been a number of methodologies and researches on how to use nano-adsorbent for wastewater treatment. This development is quite significant in that regard.
Professor Abhay Karandikar, Director, IIT-K said that “The world is reeling under several environmental hazards and water pollution is one of them. It bears direct implications on the health of humans and animals. At IIT Kanpur, our research in the field of nanotechnology is broad and diverse and this invention bears testimony to that. This crucial invention in the form of these novel nano-adsorbents would not only curb water pollution but would also be crucially beneficial for humankind.”
The uniform cubical nano-absorbent is multi-layered, bactericidal, reusable, and eco-friendly. They also have a few unique physio-chemical features that have the ability to deactivate and separate antibiotic-resistant bacteria from water.
According to Prof. Sinha, the adsorbents can remove harmful pathogens and bacteria from drinking water and improve water filtration. They can be easily used against microorganisms as they have no side effects and are compatible with the human body.
In recent years, water contamination through pharmaceutical residues is slowly increasing. Along with that, Antimicrobial Resistance (AMR) is also on the rise. This can jeopardise the effectiveness of Antibiotics during any kind of bacterial infection, and as a result be a huge threat to public health.
In such a situation, the nano-adsorbent can come in handy by effectively eliminating the antibiotic resistance bacteria from the water.
The nano-adsorbents also have the potential to be used as a component of membrane filters. They are currently being tested for clinical evaluation and bio-remediation that are ready to be commercialised.
Meanwhile, IIT Kanpur has also collaborated with Danish scientists to research Biomedical waste. The research is being conducted to know about the adverse effects of medicines and medical devices used on the patients and identify ways to prevent the negative effects.
As per the latest updates, IIT Kanpur will also install low-cost, narrow band IoT-based air quality monitoring sensors in Jaipur. The project will be conducted jointly with Rajasthan State Pollution Control Board, Airtel and Ericsson. These sensors are easy to install and of low maintenance.
