Recent Development in Nanotechnology for the Removal of Disinfection By-Products

Access to inexpensive, clean water sources is one of the UN’s Sustainable Development Goals. Rapid world population growth, climatic changes, high energy needs, and municipal and industrial pollution, which endangers freshwater reserves and a sustainable supply, have all contributed to the problem’s exponential growth. Removal of disinfection by-products is another significant issue that requires an appropriate solution. When a disinfectant interacts with organic matter that is present in nature, man-made pollutants, bromide, and iodide ions, disinfection by-products (DBPs) are created. The demand for more modern water treatment has been motivated by DBPs, a chemical water treatment problem. New strategies and better materials are required by contemporary water treatment technologies for the management and methods of conservation of water resources. Water contamination is a major cause of the spread of many infectious diseases. The key challenge is to create novel technologies that can provide enough treatment facilities without producing harmful by-products. While many traditional water treatment technologies have been used to prevent the transmission of infectious diseases that are fatal and non-fatal through the water; together with other long-range relevant technology, nanotechnology is one such technique for removing pollutants from water by adsorption or nanoparticles that serve as catalysts for oxidation of chemical or photochemical for the removal of contaminants. Nanotechnology provides the potential of ensuring the long-term availability of clean drinking water and the conservation of water resources by utilizing cutting-edge materials and procedures for conservation, purifying water, and reuse. In this chapter, we examine recent developments in nanotechnologies for water filtration, as well as their prospects, practical difficulties with commercialization, and potential dangers.
