From Biofiltration to Promising Options in Gaseous Fluxes Biotreatment: Recent Developments, New Trends, Advances, and Opportunities provides an overview on the biological tools used for the treatment of the gaseous fluxes, with emphasis on traditional and perspective options, opening new horizons for research and implementation in practice. It is known that air pollution is an emergent global issue and a priority within the international environmental programs. Moreover, technologies based on biological methods are significantly contributing to the sustainable development concept. Thus this book provides tools for solving air pollution issues in a sustainable manner. These issues can be solved at different levels (e.g., "end-of-pipe" gaseous streams, indoor/outdoor air, closed environments), which can be approached by the different biotechniques presented in the book, from classical biofiltration techniques (part 1) to phytotreatment and microalgae-based techniques (part 2). Although all options have their particularities that make them special for certain applications, a special attention is drawn to the potential of the last one, which offers multiple possibilities for biomass valorization. Scientists from worldwide with relevant experience in their field have been contributed to the development of this book. - Presents the main biotechnological aspects applied for gas purification, focusing on process understanding, limitations, and capability in different applications - Promotes a sustainable future of the biofiltration process by enhancing their performance together with the simultaneously economic and environmental impacts - Implements new aspects of scientific research and development in the field

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

The ever-increasing number of pollutants discharged into the environment drives the search for new treatment technologies or the modification of the existing ones. In this sense, innovation in bio-nano filtration systems seems very promising and, therefore, a book on the current advances and innovations on this topic is highly appropriate. Bio-nano filtration is a relatively new emerging technology applied to the treatment of wastewater and other toxic compounds. In the last two decades, this technology has begun to emerge as an economically viable process to treat the great variety of recalcitrant pollutants discharged into the environment. Thus, it is speculated that the US biofiltration market will reach over $100 million by 2020. This book aims to present how innovation in bio-nano filtration can provide effective solutions to overcome the serious problem of water pollution worldwide. The removal of contaminants will be the result of the combined effects of biological oxidation, adsorption, and filtration processes. Features: Describes the microbial ecology of bio-nano filtration. Describes the modelling of bio-nano filtration. Describes the design of bio-nanofillers.
