Handbook of Research on Resource Management for Pollution and Waste Treatment by Affam, Augustine Chioma,Ezechi, Ezerie Henry Pdf

It is necessary to understand the extent of pollution in the environment in terms of the air, water, and soil in order for both humans and animals to live healthier lives. Poor waste treatment or pollution monitoring can lead to massive environmental issues, such as diminishing valuable resources, and cause a significant negative impact on society. Solutions, such as reuse of waste and sustainable waste management, must be explored to prevent these adverse effects. The Handbook of Research on Resource Management for Pollution and Waste Treatment is a collection of innovative research that examines waste and pollution treatment methods that can be adopted at local and international levels and examines appropriate resource management strategies for environmentally related issues. Featuring coverage on a wide range of topics such as soil washing, bioremediation, and runoff handling, this book is ideally designed for environmentalists, engineers, waste management professionals, natural resource regulators, environmental policymakers, scientists, academicians, researchers, and students seeking current research on viable resource management methods for the regeneration of their immediate environment.

Coagulation and Flocculation, Second Edition by Bohuslav Dobias,Hansjoachim Stechemesser Pdf

First published in 1993, Coagulation and Flocculation is a practical reference for the researchers in the field of the stabilization and destabilization of fine solid dispersions. By omitting chapters that remained unchanged from the first edition, the editors of this second edition completely update, rewrite, and expand upon all chapters to reflect a decade of the latest advances in both theoretical and application aspects of the field. The authors provide expanded material that includes dissociation from a solid surface with independent sites; improvements to the Gouy-Chapman model; electrical double layer, surface ionization, and surface heterogeneity; thin liquid films and modeling of a semi-batch process using microprocesses probabilities; and clay mineral intracrystalline reactions, applications, and gelation. New chapters cover homopolymers and their effect on colloid stability, including never before published figures and equations; the stability of suspensions in the presence of surfactants, polymers, and mixtures; and the flocculation and dewatering of fine-particle suspensions, emphasizing floc formation, growth, structure, and applications. The second edition of Coagulation and Flocculation effectively captures both the theoretical and application aspects of the latest advances in the evolving field of solid dispersions, suspensions, and mixtures.

Flocs in Water Treatment by David H. Bache,Ross Gregory Pdf

Flocs in Water Treatment is the first of its kind - serving as a valuable aide-mémoire for scientists, process engineers and other professionals engaged in water treatment. The framework described in Flocs in Water Treatment can also be applied to aggregated solids found both in the natural environment, and within a broad range of industries. Flocs (aggregated solid matter) resulting from the combined influence of coagulation and flocculation play a vital role in solid-liquid separation processes. The design and operation of water treatment plants demands a proper understanding of the ways in which flocs affect treatment systems and how their properties can be manipulated to increase treatment efficiency. Flocs in Water Treatment provides a comprehensive account of the ways in which flocs are formed, their characterization, and how they behave in practice. Flocs are complex entities, whose properties defy easy description and measurement. In spite of this, the authors provide a clear and discerning account of the current state of knowledge; this is rooted in science and draws on many disciplines. Based on their experiences in research and the workings of full scale treatment plants, the authors offer candid advice on tasks such as the measurement of floc properties and guidance on problems involving the use of chemicals for controlling floc properties within treatment systems.

Physicochemical Treatment Processes by Lawrence K. Wang,Yung-Tse Hung,Nazih K. Shammas Pdf

The past 30 years have seen the emergence of a growing desire worldwide to take positive actions to restore and protect the environment from the degrading effects of all forms of pollution: air, noise, solid waste, and water. 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 exists, 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 identified: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? The principal intention of the Handbook of Environmental Engineering series is to help readers formulate answers to the last two questions. The traditional approach of applying tried-and-true solutions to specific pollution pr- lems has been a major contributing factor to the success of environmental engineering, and has accounted in large measure for the establishment of a “methodology of pollution c- trol. ” However, realization of the ever-increasing complexity and interrelated nature of current environmental problems makes it imperative that intelligent planning of pollution abatement systems be undertaken.

Hydrodynamic Design and Assessment of Water and Wastewater Treatment Units by Edmilson Costa Teixeira,William Bonino Rauen Pdf

Water and wastewater treatment normally take place in a series of continuous flow units, each designed to perform a step of the intended purification process - typically involving coagulation or flocculation, sedimentation or filtration, and disinfection. The flow pattern governs the residence/contact time, turbulence levels, collisions and shear to which different fluid portions are subjected in their passage through the unit. The efficiency of a given unit depends as much on the relevant physical, chemical or biological reaction as on the flow pattern taking place inside. This combined effect of flow features on process efficiency is often overlooked in teaching the design of water and wastewater treatment units, and so it is not uncommon to find treatment units in operating in a cost-ineffective way, causing health and environmental problems. This book introduces engineering students to concepts and practical measures associated with the rational design of treatment units, leading to more realistic and potentially optimal solutions for new units as well as for retrofitting existing units. Key basic concepts and suitable analytical tools are described, illustrated and worked through using practical examples. Engineering undergraduates and graduates should benefit from the book while undertaking standalone modules on the topic and/or supplementary classes of existing courses on unit treatment processes. The book may also be useful for technical and engineering staff involved in designing and/or retrofitting units for better cost-effectiveness and footprint reduction of the water and wastewater treatment sector.

Wastewater and Water Quality by Taner Yonar Pdf

Water is accepted as the most important source of life. It is assumed that life began in water and spread from there to the whole world. But water has been polluted anthropogenically since the beginning of the industrial revolution in the late 19th century. At the end of the 20th century, most water sources cannot be used for aquaculture, irrigation, and human use. Therefore, for sustainable development, we have to protect our water sources on Earth, because it's the only planet we have!

Chemical Water and Wastewater Treatment IV by Hermann H. Hahn,E. Hoffmann,Hallvard Odegaard Pdf

This seventh symposium in the series of biennial Gothenburg Symposia, taking place in Edingburgh 1996 continues to bring together research scientists, designing and operating engineers and funding and supervising administrators. It also has enlarged the scope of its platform by bringing together concerned specialists from Western countries and Central and Eastern Europe and furthermore attempts to bridge the gap between developing and industrialized countries. The traditionally presented topics, such as treatment of potable water and wastwater predominantly by chemical means are of utmost importance for those that need immediate action at reasonable costs. It is particularly noteworthy that an increasing number of contributions address these problems of the emerging need for environmental protection. And more and more presentations are delivered by experts from Central and Eastern Europe and from developing countries. Again the proceedings of this seventh symposium indicate and demonstrate new developments that advance the field of water and wastewater treatment. Be sides the ever present topics there is now a whole section on automation and control, a highly significant topic for water technology that so far has not received too much attention in symposia of this kind addressing theoreticians and prac titioners at the same time.

Chemical Water and Wastewater Treatment II by Rudolf Klute,Hermann H. Hahn Pdf

With joy and pride parents observe the coming of age of their children, confer. , ence conveners the acceptance of their programmes, and editors the demand for their volumes. The scientific advisory board of the Gothenburg . . Symposia, the Springer publishing house of the proceedings and the editors are more than pleased with the fact that the demand for these books far exceeds the supply. The themes vocalized by the Gothenburg Symposia reHect research and development needs for the environment more than envisioned at the concep tion of the conferences. An environment-oriented analysis of the situation, not confined to the European community, furnishes the following results: (1) Due to the very high population density in many areas environmental quality is endangered; this has become apparent at the very moment in particular in the aqueous habitat and is corroborated by corresponding regulation proposals from the European Council. (2) Pollution control concepts and measures are developed to a varying degree in many countries of the world, reHecting in most instances the need for environmental protection and the closely related devel opment of (judicial and technical) measures. In most instances these controlling and protective measures need to be intensified. (3) Thus, nearly all countries face the problem of developing and/or improving pollution control strategies, i. e. building new treatment plants, upgrading overloaded or outdated instal lations and designing new operating and controlling strategies for improved plant performance.
