Among various water and wastewater treatment technologies, the adsorption process is considered better because of lower cost, simple design and easy operation. Activated carbon (a universal adsorbent) is generally used for the removal of diverse types of pollutants from water and wastewater. Research is now being directed towards the modification of carbon surfaces to enhance its adsorption potential towards specific pollutants. However, widespread use of commercial activated carbon is sometimes restricted especially in developing or poor countries due to its higher costs. Attempts are therefore being made to develop inexpensive adsorbents utilizing abundant natural materials, agricultural and industrial waste materials. Use of waste materials as low-cost adsorbents is attractive due to their contribution in the reduction of costs for waste disposal, therefore contributing to environmental protection. This e-book explores knowledge on recent developments in adsorbents synthesis and their use in water pollution control. This handy reference work is intended for researchers and scientists actively engaged in the study of adsorption and the development and application of efficient adsorption technology for water treatment. This e-book covers a wide range of topics including modeling aspects of adsorption process and the applications of conventional and non-conventional adsorbents in water remediation emphasizing sorption mechanisms of different pollutants on the adsorbents.

This book compiles 15 chapters about the synthesis, characterizations, and application of many kinds of magnetic adsorbents for water treatment. It is devoted to the scientific community that works with adsorption technologies for water treatment and remediation. Specifically, for professors and Ph.D. students. It is expected that this book serves as an interesting background for researchers in the field of magnetic adsorbents for water treatment.

Advanced Water Treatment: Adsorption discusses the application of adsorption in water purification. The book reviews research findings on the preparation of five different nano/microcellulose-based adsorbents, their characterization, the study of adsorption kinetics and isotherms, the determination of adsorption mechanisms, and an evaluation of adsorbents' regeneration properties. The book describes modification microfibrillated cellulose (MFC), the use of succinic anhydride modified mercerized nanocellulose, and aminosilane and hydroxyapatite modified nanostructured MFC for the removal of heavy metals from aqueous solutions. Final sections describe the use of aminosilane, epoxy and hydroxyapatite modified MFC as a promising alternative for H2S removal from aqueous solutions, along with new findings on the adsorption properties of carbonated hydroxyapatite modified MFC as multifunctional adsorbent for the removal of both cations and anions ions from water. - Includes the most recent research on advanced water treatment by adsorption - Provides the latest updates on novel absorbents for water purification - Describes REE removal using various absorbents - Covers a wide range of methods and their integration

This book provides researchers and graduate students with an overview of the latest developments in and applications of adsorption processes for water treatment and purification.

With this book, you can choose from a wide variety of traditional and novel adsorbents, including alternative, relatively inexpensive adsorbents.

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
