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. The book explores practical methodologies for transforming water using nanotechnologies and is a comprehensive reference for food science research professionals, professors, and students. It includes up-to-date information on nanotechnology applications and research methods for water purification, presents applications of engineered nanomaterials to improve efficiency and reduce cost, provides water purification research methods (precipitation, adsorption, membrane separation, ion exchange), and covers potential risks such as toxicological effects of engineered nanomaterials.
