Innovative Materials and Methods for Water Treatment

Due to increasing demand for water potable and irrigation, water suppliers have to use alternative resources. They either have to regenerate wastewater or deal with contaminated surface water. This book brings together the experiences of various experts in preparing innovative materials selective for arsenic and chromium and performing innovative processes for removal of these two elements from water and will be of interest to engineers and decision makers responsible for safe water production and delivery. The book is divided into two parts. The first part presents the studies on preparation of innovative materials with improved affinity towards arsenic as well as chromium. The second part shows the innovative methods for removal of these toxic elements and discusses the chromatographic, membrane, and hybrid systems. The book is the first ever scientific work addressed to two most harmful elements appearing in water and provides a comprehensive review of materials and methods useful for making the water safe. The book discusses in detail the various fabrication techniques for sorbents and membranes that are now commercially available and employed or in the development stage and to be commercialized in the next decades. Some of the technologies described in the second part will be implemented at industrial scale in the future as well.
