@ Karunesh, I think carbon nanotube combined with electrochemistry proved to be the best method for water and wastewater purification. Beside this, silver nanoparticles are good antimicrobial agents, they are widely used to disinfect water.

Nanomaterials have shown great potential in treating wastewater due to their unique properties. Here are some of the best nanomaterials and techniques for wastewater treatment:

Nano-adsorbents

Nanomembranes

Nanophotocatalysts

Nanostructured catalytic membranes

These nanomaterials and techniques are eco-friendly and efficient in removing pollutants from wastewater. However, further research is needed to optimize their use and ensure.

Nanomaterials are products of nanotechnology from which nanoparticles are derived. Notable engineered nanomaterials include amorphous silicon dioxide, carbon nanotubes, titanium dioxide, copper oxide, Zinc oxide, and others. Each of these nanomaterials has its unique usefulness in such fields of human endeavor as agriculture, environment, industries, transport, healthcare, material science, energy, and information technologies, where it is most suitable.

Concerning wastewater treatment, I reckon that carbon nanotubes are the best nanomaterials that currently exist, especially when properly processed and utilized as adsorbents for removing micropollutants via adsorption systems.

I believe, rather than asking about nanomaterials, we should ask about the mechanism of treatment of water and/or wastewater by nanoparticles. I hope that everybody read well about the mechanisms of treatment before unknowingly flattering the nanotechnology. The nanoparticles are just materials, and those materials could be used in coagulation, filtration, or adsorption etc. The treatment of water and wastewater is not like other fields of using nanotechnology such as electronic and other industries.

Important to mention that the existence of nanoparticles in water even in trace amounts could be a problematic in the field of water quality management.

Nanomaterials and nanotechniques have shown great promise in wastewater treatment due to their unique properties and high reactivity. Some of the best nanomaterials and techniques for wastewater treatment are:

It's important to note that while nanomaterials offer significant advantages in wastewater treatment, their potential environmental and health impacts should also be considered. Proper synthesis, handling, and disposal of nanomaterials are essential to ensure their safe application in water treatment processes. Additionally, the choice of nanomaterial and technique depends on the specific contaminants present in the wastewater and the treatment objectives.

Dear Dr tewari

Nanomaterials and techniques commonly employed in wastewater treatment include:

It's important to note that the effectiveness of a particular nanomaterial or technique depends on the specific pollutants present in the wastewater, as well as factors such as cost, scalability, and potential environmental impacts.
