Book excerpt: Design of packed-tower air-stripping systems for the removal of volatile contaminants from groundwaters requires knowledge of the equilibrium constant relating air and water concentrations (Henry's constant, H), and the applicable mass transfer coefficient (K sub 1a). The objectives of this research were: to evaluate the effects of temperature, ionic strength, and the mutual presence of other organics on the H-values of five volatile compounds of concern to the USAP; and to investigate the effects of temperature, packing size and type, liquid and air loadings, and the mutual presence of other organics on the K sub 1a values of these five compounds--tetrachloroethylene, trichloroethylene, 1,1,1-trichloroethane, chloroform, and methylene chloride. An innovative method for measuring Henry's constants was proposed and evaluated, termed Equilibrium Partitioning In Closed Systems (EPICS). This method relies upon measurement of the ratio of headspace concentrations from two equilibrated bottles containing equal solute masses, but possessing differing liquid volumes. H-values for the five compounds were measured over temperatures ranging from 10 to 30 C using both EPICS and batch, diffused-bubble stripping techniques. Temperature regressions for H were derived. Comparison between methods suggests that EPICS is as precise as the batch-stripping technique, and is probably more accurate, being free of mass transfer limitations. Liquid-phase diffusivity values were measured for the five study compounds at 20 C using a diaphragm diffusion cell.

Available in PDF, EPUB and Kindle. Book excerpt: Water Pollution Control in Asia documents the proceedings of the Second IAWPRC Asian Conference on Water Pollution Control, held in Bangkok, Thailand, 9-11 November 1988. The conference brings together the various factors that must be considered when investigating the development of water supply and control of sewage disposal systems, especially for small villages or towns and large communities in Asia which are situated too far from a piped system of water supply, thus requiring its own sources treatment and sewage disposal. The contributions made by researchers at the conference are organized into seven parts. Part 1 examines the various aspects of water quality management. The papers in Part 2 deal with the analysis and cleanup of river, lake, and marine pollution. Part 3 discusses the treatment of human waste while Part 4 is devoted to industrial waste treatment approaches. Part 5 focuses on water treatment methods. Part 6 contains studies on water reuse and groundwater contamination. The papers in Part 7 cover various topics such as wastewater management in developing countries and the treatment of phenolic wastewater using rotating biological contactors.

This book was released on 2007-11-10 with total page 697 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past thirty years have witnessed a growing worldwide desire that po- tive actions be taken to restore and protect the environment from the degr- ing effects of all forms of pollution—air, water, soil, and noise. Because pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unrealistic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been id- tified: (1) How serious is the pollution? (2) Is the technology to abate it ava- able? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers f- mulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to specific pollution problems has been a major contributing factor to the success of en- ronmental engineering, and has accounted in large measure for the establi- ment of a “methodology of pollution control. ” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.

Available in PDF, EPUB and Kindle. Book excerpt: The unit process approach, common in the field of chemical engineering, was introduced about 1962 to the field of environmental engineering. An understanding of unit processes is the foundation for continued learning and for designing treatment systems. The time is ripe for a new textbook that delineates the role of unit process principles in environmental engineering. Suitable for a two-semester course, Water Treatment Unit Processes: Physical and Chemical provides the grounding in the underlying principles of each unit process that students need in order to link theory to practice. Bridging the gap between scientific principles and engineering practice, the book covers approaches that are common to all unit processes as well as principles that characterize each unit process. Integrating theory into algorithms for practice, Professor Hendricks emphasizes the fundamentals, using simple explanations and avoiding models that are too complex mathematically, allowing students to assimilate principles without getting sidelined by excess calculations. Applications of unit processes principles are illustrated by example problems in each chapter. Student problems are provided at the end of each chapter; the solutions manual can be downloaded from the CRC Press Web site. Excel spreadsheets are integrated into the text as tables designated by a "CD" prefix. Certain spreadsheets illustrate the idea of "scenarios" that emphasize the idea that design solutions depend upon assumptions and the interactions between design variables. The spreadsheets can be downloaded from the CRC web site. The book has been designed so that each unit process topic is self-contained, with sidebars and examples throughout the text. Each chapter has subheadings, so that students can scan the pages and identify important topics with little effort. Problems, references, and a glossary are found at the end of each chapter. Most chapters contain downloadable Excel spreadsheets integrated into the text and appendices with additional information. Appendices at the end of the book provide useful reference material on various topics that support the text. This design allows students at different levels to easily navigate through the book and professors to assign pertinent sections in the order they prefer. The book gives your students an understanding of the broader aspects of one of the core areas of the environmental engineering curriculum and knowledge important for the design of treatment systems.

Available in PDF, EPUB and Kindle. Book excerpt: Explains the fundamental theory and mathematics of water and wastewater treatment processes By carefully explaining both the underlying theory and the underlying mathematics, this text enables readers to fully grasp the fundamentals of physical and chemical treatment processes for water and wastewater. Throughout the book, the authors use detailed examples to illustrate real-world challenges and their solutions, including step-by-step mathematical calculations. Each chapter ends with a set of problems that enable readers to put their knowledge into practice by developing and analyzing complex processes for the removal of soluble and particulate materials in order to ensure the safety of our water supplies. Designed to give readers a deep understanding of how water treatment processes actually work, Water Quality Engineering explores: Application of mass balances in continuous flow systems, enabling readers to understand and predict changes in water quality Processes for removing soluble contaminants from water, including treatment of municipal and industrial wastes Processes for removing particulate materials from water Membrane processes to remove both soluble and particulate materials Following the discussion of mass balances in continuous flow systems in the first part of the book, the authors explain and analyze water treatment processes in subsequent chapters by setting forth the relevant mass balance for the process, reactor geometry, and flow pattern under consideration. With its many examples and problem sets, Water Quality Engineering is recommended as a textbook for graduate courses in physical and chemical treatment processes for water and wastewater. By drawing together the most recent research findings and industry practices, this text is also recommended for professional environmental engineers in search of a contemporary perspective on water and wastewater treatment processes.
