Nano-techniques: a tool to prevent disinfection by-product formation in drinking water

Water, a vital component required by all living things, becomes more and more polluted as a result of globalisation and industrialisation. Currently, pathogenic microbes, emerging pollutants, industrial chemicals and waste are polluting all-natural water resources and transportation systems. Therefore, before usage, drinking water has to be treated. When water disinfectants react with the organic natural components found in source waters, they may unintentionally produce disinfection by-products (DBPs), which have a negative impact on the biological system. There is a need for the development of innovative water-treatment solutions since traditional drinking water treatment (DWT) does not reduce emerging contaminants. The main objective of this study is to give an overview of disinfection techniques, DBP generation, health consequences and environmental repercussions. Additionally, there are advancements in nanotechnology that have been made in drinking water system treatment for the prevention of DBP and contaminant removal. Further review describes the analysis of advanced DWT processes that can be employed for the removal and control of precursors and DBPs.
