Water purification with nano-filters
Application of Nanoparticles in Waste Water Treatment – no doubt that nanotechnology has a big ability to change our life completely, as these very tiny particles incorporated in all fields especially medicine, industry, and agriculture.
The study that we will illustrate in this article discusses the role of some nanoparticles in the purification of water from many wastes to use clean water and re-use the wastewater safely.

Review: there are some researchers in India who says that they investigate some nano-particles in water purification, such as carbon nanotubes, nano filters, nanocatalysts, Nanosensors, and magnetic nanoparticles to get rid of any wastes and microbes, and detect contaminants in the previously used water.
Application of Nanoparticles in Waste Water Treatment
The teamwork also showed that the purification grade controls the wastes and impurities which nanoparticles can tackle, and the purification process also depends on the nanotechnology and other techniques, they add that these techniques can detect the toxic chemicals, microorganisms (i.e: Bacteria, fungi, worm ova, etc.), and liquid wastes especially oils.
Researchers say that the main benefit of the application of nanomaterials and biotechnology in the field of water and wastewater treatment is the no need of high pressure to force water across these tiniest filters; so the water is easy to be cleaned when compared with other water purification methods.
The carbon nanotubes mostly can remove all contaminants and pathogens in water especially: oils, bacteria, fungi, viruses, organic compounds, and some elements such as arsenic. Although the smaller pore in carbon nanotubes; it has a flow rate equal and sometimes faster than the larger pores.
Besides that, the nanofibrous alumina filters and some other nanomaterials have a good effect in removing all harmful and -ve charged contaminants and pathogens from water.
nanotechnology and water pollution
The scientists say that, although the simplicity of Water purification with nano-filters and nanomaterials nowadays; it is very important to develop water treatment devices based on nanotechnology techniques to get very clean and pure water; which will surely result in getting rid of many infections and Diseases eradication
nanotechnology in water purification
They also point out that some researchers think that the nanomaterials may have a higher affinity to react with water wastes and pathogens because of its higher surface area when compared to the bulk material (area: volume ratio), so these nanomaterials may have unrecognized and untested interactions with pathogens and biological surfaces.
But we have to tell you that there is no harmful effect on human health when using water purification methods based on nanotechnology yet.
The main advantage of using nanoparticles is its easy preparation and no harmful side effects on human or environment, but it is very important to further studies and tests to uncover the biological interactions of nanoparticles In order to confirm its safety on the human being
