The deterioration of water quality and unavailability of drinkable water are pressing challenges worldwide. The removal of toxic organic and inorganic pollutants from water is vital for a clean environment, as a response to water scarcity. Adsorption-based water technologies are among the most widely used because of their high efficiency and low cost, without relying on a complex infrastructure. In recent years, carbon nanomaterials (CNMs), such as graphene and derivatives, carbon nanotubes, carbon nanofibers, nanoporous carbon, fullerenes, graphitic carbon nitride, and nanodiamonds have been extensively exploited as adsorbents due to their extraordinary surface properties, ease of modification, large surface area, controlled structural varieties, high chemical stability, porosity, low density, ease of regeneration, and reusability. This book provides a thorough overview of the state of the art in carbon nanomaterials as they are used for adsorption applications in water purifications, as well as addressing their toxicological challenges. This volume primarily explores the fundamentals of adsorption, its mechanical aspects, synthesis and properties of CNMs, and adsorption performances of CNMs and their nanocomposites with organic and inorganic materials. Structural engineering and activation processes produce materials with enhanced adsorptive properties and separation efficiencies. Furthermore, the formation of CNMs with 2D and 3D macro-and microstructures and high porosities is a potential approach to improve adsorption performances and extend CNM use at the industrial level. The book also addresses important issues regarding these adsorbents that potentially affect future research and industrial applications of carbon-based nanoadsorbents in water security. - Presents advances in multifunctional 3D superstructures of carbon nanomaterials and their composites for adsorption applications - Outlines the fundamentals on synthesis and characterization techniques of carbon-based nanostructures and their composites - Assesses the major toxicological challenges in using nanostructured materials as adsorbents for water purification

High-Risk Pollutants in Wastewater presents the basic knowledge regarding the diversity, concentrations, and health and environmental impacts of HRPs in municipal wastewater. The book summarizes information on the types (e.g. heavy metals, toxic organics and pathogens) and toxicities of HRPs in wastewater. In addition, it describes ecological and health hazards arising from the living things' direct/indirect contacts with the HRPs during their full lifecycles (generation, disposal, discharge and reuse) in wastewater or water environments. Sections cover the concepts of appropriate technology for HRP hazard/risk assessment and wastewater treatment/reuse and the issues of strategy and policy for increasing risk control coverage. Finally, the book focuses on the resolution of water quality monitoring, wastewater treatment and disposal problems in both developed and developing countries. - Presents information on HRPs and their risk assessment and control technologies - Provides basic knowledge regarding the diversity, concentrations, and health and environmental impacts of HRPs in municipal wastewater - Summarizes information on the types (e.g. heavy metals, toxic organics and pathogens) and toxicities of HRPs in wastewater
