Water Purification, a volume in the Nanotechnology in the Food Industry series, provides an in-depth review of the current technologies and emerging application of nanotechnology in drinking water purification, also presenting an overview of the common drinking water contaminants, such as heavy metals, organics, microorganisms, pharmaceuticals, and their occurrences in drinking water sources.

As the global water crisis has motivated the industry to look for alternative water supplies, nanotechnology presents significant potential for utilizing previously unacceptable water sources. This books explores the practical methodologies for transforming water using nanotechnologies, and is a comprehensive reference to a wide audience of food science research professionals, professors, and students who are doing research in this field.

• Includes the most up-to-date information on nanotechnology applications and research methods for water purification and treatment
• Presents applications of nanotechnology and engineered nanomaterials in drinking water purification to improve efficiency and reduce cost
• Provides water purification research methods that are important to water quality, including precipitation, adsorption, membrane separation, and ion exchange
• Covers the potential risks of nanotechnology, such as the toxicological effects of engineered nanomaterials in water and how to minimize risks based on research studies

Abstract

Decision makers as well as peoples are gradually aware about the importance of the environmental protection and increasing attention is paid for annihilate the negative aspects related to the humankind activities (industrial, agricultural, or domestic activities). In this context, the development of new materials or optimizing existent ones for environmental applications and especially for water purification is increasing as importance. The current work is devoted to the identification of the most used classes of nanomaterials for environmental applications, the mechanisms of water purification as well as the advances in this field induced by the synergic use of more components, especially magnetic materials and metals and metal-oxides, carbon-based materials, or silicates. The main advantages of the use of composite materials and core–shell structures are related to the individual properties, as well as due to the synergy between these components. The nanometric range of these materials is important because assure a high specific surface area and consequently high...
