Application of Nanomaterials in Water Purification: A review

Abstract

Providing clean water all over the world at low cost to meet human needs is a big challenge in the current century. As the world strives to keep pace with the increasing demand for clean water as quickly as possible due to the permanent increase in population density and the deterioration of the state of water and its quality in addition to climate changes. The requirement for developing technological innovations incorporated water managing can't be exaggerated. As reached by previous researchers, nanotechnology possesses vast capabilities to improve water treatment and purify it from organic and inorganic pollutants through the safe use of unconventional water sources. This review covers the methods that have been examined both laboratory and commercially in purifying and treating water. This research provides a discussion of the used methods, advantages and their limitations and also covers a study of nanomaterials used as photocatalysts, whether manufactured or under study. This is done by studying and reviewing the chemical and physical properties of these nanomaterials and their applications in treating water pollution.
