Microbial Impact Of Biological Filtration

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

Slow sand filtration is typically cited as being the first "engineered" process in drinking-water treatment. Proven modifications to the conventional slow sand filtration process, the awareness of induced biological activity in riverbank filtration systems, and the growth of oxidant-induced biological removals in more rapid-rate filters (e.g. biological activated carbon) demonstrate the renaissance of biofiltration as a treatment process that remains viable for both small, rural communities and major cities. Biofiltration is expected to become even more common in the future as efforts intensify to decrease the presence of disease-causing microorganisms and disinfection by-products in drinking water, to minimize microbial regrowth potential in distribution systems, and where operator skill levels are emphasized. Recent Progress in Slow Sand and Alternative Biofiltration Processes provides a state-of-the-art assessment on a variety of biofiltration systems from studies conducted around the world. The authors collectively represent a perspective from 23 countries and include academics, biofiltration system users, designers, and manufacturers. It provides an up-to-date perspective on the physical, chemical, biological, and operational factors affecting the performance of slow sand filtration (SSF), riverbank filtration (RBF), soil-aquifer treatment (SAT), and biological activated carbon (BAC) processes. The main themes are: comparable overviews of biofiltration systems; slow sand filtration process behavior, treatment performance and process developments; and alternative biofiltration process behaviors, treatment performances, and process developments.

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.

Biofiltration is a relatively emerging new technology applied to the treatment of wastewater and other toxic substances. Over the past two decades, this technology has become an economically viable process for treating the wide variety of unruly pollutants released into the environment. For example, it is speculated that the US biofiltration market will reach more than $100 million by 2020. This book aims to show how innovation in biofiltration can provide effective solutions to overcome the serious problem of water pollution worldwide. The removal of contaminants will result from the combined effects of biological oxidation, adsorption, and filtration processes.

UV-Visible Spectrophotometry of Water and Wastewater is the first book dedicated to the use of UV spectrophotometry for water and wastewater quality monitoring. Using practical examples the reader is shown how this technique can be a source of new methods of characterization and measurement. Easy and fast to run, this simple and robust analytical technique must be considered as one of the best ways to obtain a quantitative estimation of specific or aggregate parameters (eg. Nitrate, TOC), and simultaneously qualitative information on the global composition of water and its variation. * First electronic library of UV-spectra providing data readily available for researchers and users * Provides a theoretical basis for further research in the field of spectra exploitation * Contains helpful practical applications
