A Mini Overview of Wastewater and River Water Treatment by Various Nanoparticles
Summary
This mini-review covers how various metal-based and metal-free nanoparticles are used to treat contaminated water, removing heavy metals, dyes, and emerging pollutants. Nanoparticle-based water treatment is also being explored for microplastic removal, complementing conventional filtration technologies.
Nowadays nanoparticles are utilized vastly for several purposes. Wastewater treatment is a term where both metal based, and metal free nanoparticles are employed. In the case of water such as river water, ground water, sea water, industrial wastewater etc. are contaminated for which we cannot use this in our needs by utilizing nanoparticles This water can be treated by se veral processes such as photocatalysis, adsorption, antimicrobial treatment, desalination, and others. By photocatalysis, dye contaminated water is treated with dye degradation. Sea water can be treated by desalination. In ground water, there are several heavy metals which can be absorbed by nanoparticles for the reason of high surface area of these. River water along with other waters contains sever al microbial organisms and remains unsafe in utilization. As nanoparticles have antimicrobial properties, they can treat this contamination. In our study we will give a short overview of wastewater treatment by nanoparticles.
