An Innovative Role Of Biofiltration In Wastewater Treatment Plants

Many physico-chemical and operational factors influence the performance, treatment costs and long-term stability of biofilters for the treatment of wastewater. An Innovative Role of Biofiltration in Wastewater Treatment Plants focuses on identifying the factors that affect biofiltration, such as the hydraulic retention time of the biofiltration system, the type and characteristics of the filter and the attached biomass, explains their influence and provides guidelines on how to control these factors to optimize better operation with respect to pollutant control present in wastewater treatment plants (WWTPs). The fundamental basis of treatment in biofilters is the action of pollutant-degrading microorganisms and consequently the book also discusses in depth about the microbial ecology of biofiltration. In addition, it explores the applications of biofiltration including the removal of emerging pollutants. Describes the microbial ecology of biofiltration Includes modeling of biofiltration Describes the designing of biofilters, start-up, and monitoring Discusses the mechanism of biofiltration Describes the controlling and operational factors of biofiltration

Sustainable and Circular Management of Resources and Waste Towards a Green Deal highlights the importance of resource recovery, phosphorus management, climate action, clean energy transition, and a circular economy. The world is facing significant challenges, including climate disruption, environmental changes, pollution, and population explosion. Sustainable management of finite natural resources within the carrying capacity of the bio-geo-hydrosphere is the crux of transforming the global economy for a sustainable future. Moreover, keeping raw materials in circulation as long as possible and minimizing the amount of waste generated has grown in significance as a part of transitioning to a circular economy (CE) model. Introduces innovative solutions in green energy transition Provides case studies as examples of a circular economy implementation in selected sectors of the economy, including water and wastewater, raw materials, and construction Suggests actions to counteract climate change and its consequences for people and the planet

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.

This book identifies emerging technologies that allow the reuse and regeneration of industrial wastewater with innovative and applied approaches throughout the wastewater treatment cycle. Today, it is increasingly clear that treated urban wastewater, whose reuse has become an important component of long-term water management worldwide, is a key source of chemical pollutants and emerging biological concerns. Current water-quality guidelines for reclaimed wastewater predominantly address the risks associated with the presence of microbial organisms and chemical parameters such as biological oxygen demand, chemical oxygen demand, E. coli and worms, and in some cases heavy metals; however, they are insufficient for the full evaluation of risks. The global growth of population is concentrated in urban areas; therefore, most of the challenges and solutions related to wastewater reside in urban treatment plants. Unless wastewater management and wastewater governance processes are significantly improved within a decade, it is likely that our societies will face severe and prolonged water insecurity and urban floods. The application of sustainable technologies can eliminate or minimize micro-contaminants in wastewater. Several organizations focus on the potential impacts to humans and their environments by wastewater reuse. This book gathers new research and reviews work from researchers and scientists to identify the main barriers and limitations that will need to be overcome, so that wastewater reuse strategies gain more momentum and will be adopted more efficiently worldwide. The book is designed for engineers, scientists, and other professionals who are seeking an excellent introduction to and basic knowledge of the principles of environmental bioremediation technologies.

The book highlights the importance of newly developed bioremediation technologies in industrial waste treatment to clean up the environment from pollution caused by human activities. It assesses the potential application of several existing bioremediation techniques and introduces new emerging and application-based technologies. This technology includes several techniques such as bio-stimulation, bio-generation, bioaccumulation, biosorption, physical correction and rhyming-emission. This book describes the limitations and challenges associated with some generally accepted bioremediation strategies and evaluate the possible applications of these corrective strategies to eliminate toxic pollutants from the environment through integrated Technologies in Industrial wastewater treatment.
