Book Description
This book discusses the problems and feasible remediation of fluoride contamination in groundwater. The book investigates applications of various carbons derived from bio-mass and bio-polymers. It also inquires into surface modified carbons that use inorganic ions to help remove excess fluoride ions in drinking water and wastewater effluents. The compliance of kinetic and isotherm models with fluoride sorption is covered, and the suggested mechanisms of defluoridation by surface modified carbon materials is described.

Book Description
With an increased demand for wastewater reuse, groundwater recharge with treated wastewater has been practiced across the globe. As a result, groundwater quality deteriorates by emerging micropollutants from various anthropogenic origins, including untreated wastewater, seepage of landfill leachate, and runoff from agricultural lands. The fate of such emerging and geogenic contaminants in subsurface systems, especially in the groundwater, depends on several factors. Physicochemical properties of contaminants such as octanol-water partition coefficient, dissociation constant, water solubility, susceptibility to biodegradation under anaerobic conditions, and environmental persistence under diverse geological and pH conditions play a critical role during subsurface mass flow. Thus, advanced wastewater treatment techniques, followed by implementing stricter guidelines, are some of the measures that can safeguard water resources. This book, in general, gives an understanding of the fate and mitigation strategies for emerging and geogenic contaminants in the groundwater. The first and second sections provide a detailed insight into various removal techniques and mitigation approaches. Possible treatment strategies, including bioremediation and natural attenuation, are also covered in those sections. Environmental assessment, groundwater vulnerability, health effects, and regulations pertaining to various contaminants are systematically presented in the third section.

Book Description
The reclamation of wastewater (and other essential materials) is among the major research areas for understanding the effects of implementing a circular economic model. The re-use and re-cycling of wastewater can greatly reduce the overall demand for freshwater for various industrial applications. Such concepts could potentially greatly reduce the overall water demands of our planet if implemented successfully. Circular Economy: Applications for Water Remediation will examine the current understanding of the circular economy in water remediation processes, its drawbacks, and relatively unexplored areas that require further research. This book: • Provides an overview of the processes available to extract value-added materials from wastewater, such as clean water, nutrients, and energy. • Explores the possibilities of re-using wastewater for agricultural uses. • Provides an overview of the current policies and regulations concerning the implementation of circular economy concepts in wastewater remediation.

Book Description
This book presents an overview of the techniques available today for the removal of fluoride contamination/pollutants/species from water. Also covered are traditionally applied techniques for the removal of fluoride pollutants/species, including oxidation, coagulation-flocculation, and membrane techniques. Recently, progress has been made on the utility of various nanoparticles for the extraction of contaminants from water. Fluoride contamination is affecting water resources quality worldwide as a result of human activities, such as mining and pesticide use. Due to the high risk of fluoride exposure, specific water treatment processes are required to meet more severe water quality standards. A better understanding of currently available processes is necessary to develop economical, efficient, and effective methods for fluoride removal. Fluoride can either be coated, adsorbed using a wide range of both mineral and organic constituents or can be directly rejected by membrane processes, such as reverse osmosis and nanofiltration. Recent developments of submerged hybrid membrane systems, such as membrane bioreactors in wastewater treatment, provide alternative technologies for fluoride treatment.
