Download or read book Modeling Physicochemical Processes of Microbial Transport in Porous Media written by Li Cheng and published by . This book was released on 2006 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The traditional colloid filtration model has been recognized to not fully describe transport of microorganisms in porous media under many conditions. Potential reasons for the discrepancies between colloid filtration theories and observed data are summarized into three aspects in the dissertation, including physicochemical heterogeneity, a blocking effect in the attachment process, and irreversible straining. A new transport model is developed to incorporate these non-ideal phenomena. First, both the collision-efficiency coefficient and the detachment-rate coefficient are formulated as probability density functions with log-normal distributions to represent physicochemical heterogeneity of both microbial and porous-medium grain surfaces. Second, the blocking effect is represented by appending a modified random sequential adsorption (RSA) function to the kinetic rate equation. Third, a semi-empirical equation is developed to describe the straining effect. The new model is then evaluated with a series of sensitivity analyses and illustrative applications to measured data. Sensitivity analysis on the role of probability density function (PDF) in collision efficiency and detachment rate coefficient shows that heterogeneity causes longer tailing in breakthrough curves, This effect is controlled by the implementation of the PDF in the detachment rate coefficient because the lower values among a series of detachment rate coefficients delay detachment. Straining phenonmena have received more and more attentions for protozoa transport. The new semi-empirical straining equation derived in the dissertation provides reasonable matches to the colloid data and cryptosporidium data. The Blocking effect is another process of concern for microbial transport, as shown in the analysis of microsporidium column experiments herein. The new model also proved to be successful for simulating MS-2 virus transport. The work presented will help enhance our understanding of biocolloid transport in porous media.

Download or read book Modelling of Pollutants in Complex Environmental Systems written by Grady Hanrahan and published by ILM Publications. This book was released on 2010 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental modelling has enjoyed a long tradition, but there is a defined need to continually address both the power and the limitations of such models, as well as their quantitative assessment. This book showcases modern environmental modelling methods, the basic theory behind them and their incorporation into complex environmental investigations. It highlights advanced computing technologies and how they have led to unprecedented and adaptive modelling, simulation and decision-support tools to study complex environmental systems, and how they can be applied to current environmental concerns. This volume is essential reading for researchers in academia, industry and government-related bodies who have a vested interest in all aspects of environmental modelling. Features include: A range of modern environmental modelling techniques are described by experts from around the world, including the USA, Canada, Australia, Europe and Thailand; many examples from air, water, soil/sediment and biological matrices are covered in detail throughout the book; key chapters are included on modelling uncertainty and sensitivity analysis; and, a selection of figures are provided in full colour to enable greater comprehension of the topics discussed.

Download or read book Riverbank Filtration: Understanding Contaminant Biogeochemistry and Pathogen Removal written by C. Ray and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Riverbank filtration is widely used in Europe and to some extent in the United States for the public water supply. It is a cost-effective and realisable treatment technology in which horizontal and vertical wells pump a mixture of ground water and induced surface water from a river. This book describes the biogeochemical issues involved in contaminant removal from surface water and the mechanisms of pathogen removal. Specifically, the following three points are considered: *The role of hydrogeological and well construction factors in the development of redox zones at bank filtration sites and the resulting impacts on contaminant removal. *The mechanisms of pathogen removal, including the processes, colloid filtration, die-away, decay, and predation. *The status of riverbank filtration processes in NATO partner countries.

This book was released on 2023-01-05 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives insight into several aspects of the microbiology, biotechnology, and ecosystem sustainability of special and under-explored regions, that captivate human beings by their natural richness, their extensive biodiversity, the extraordinary forms of adaptation of the living beings that they inhabit, and even that keep living secrets as is the very origin of life. The chapters emphasize all aspects of biological diversity-its description, analysis, and conservation, and its controlled rational use by humankind. Also, the book is elaborated from a wide and multidisciplinary point of view. It presents reviews, research papers, comments, and research notes on biodiversity, ethnobiology, geoscience, chemistry, biological conservation, biotechnology, and ecosystem sustainability Two hotspots are the reference for this enriching book that describes details of extraordinary areas of the planet, from Cuatrociénegas, Coahuila (Mexico) to the Southern Western Ghats (India). The book will contribute to dealing with the practicalities of conservation management, economic, social, and political issues. It provides a forum for examining conflicts between sustainable development and human dependence on biodiversity in agriculture, environmental management, and biotechnology, and encourages contributions from developing countries to promote broad global perspectives on matters of biodiversity and conservation.
