Flotation Technology


Book Description

The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution – air, water, soil, and noise. Since pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unreal- tic 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 identi?ed: (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? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to speci?c pollution p- blems 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 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.

Environmental and Natural Resources Engineering


Book Description

This volume has been designed to serve as a natural resources engineering reference book as well as a supplemental textbook. This volume is part of the Handbook of Environmental Engineering series, an incredible collection of methodologies that study the effects of resources and wastes in their three basic forms: gas, solid, and liquid. It complements two other books in the series including "Natural Resources and Control Processes" and "Advances in Natural Resources Management". Together they serve as a basis for advanced study or specialized investigation of the theory and analysis of various natural resources systems. This book covers many aspects of resources conservation, treatment, recycling, and education including agricultural, industrial, municipal and natural sources. The purpose of this book is to thoroughly prepare the reader for understanding the available resources, protection, treatment and control methods, such as bee protection, water reclamation, environmental conservation, biological and natural processes, endocrine disruptor removal, thermal pollution control, thermal energy reuse, lake restoration, industrial waste treatment, agricultural waste treatment, pest and vector control, and environmental engineering education. The chapters provide information on some of the most innovative and ground-breaking advances in environmental and natural resources engineering from a panel of esteemed experts.




Dissolved Air Flotation For Water Clarification


Book Description

The definitive work on Dissolved Air Flotation Systems (DAF) for clarification of drinking water Dissolved Air Flotation for Water Clarification is a complete design and application source for the water industry divided into three parts: The first develops a fundamental basis for understanding how the process works, and might be adapted to work better. The second provides a reference for design engineers, water operators, and water managers regarding applications where DAF might be incorporated in an overall treatment scheme. The third develops the necessary DAF design concepts and to illustrate them by description of practical applications. Using DAF to remove particles is not only an important process for conventional drinking water plants, but may also be used as a pre-treatment process in membrane plants including reverse osmosis for water desalinization, and in water reuse applications. Dissolved Air Flotation for Water Clarification offers: Information on new applications of DAF in advanced water treatment, desalinization, water reuse, and industrial treatment in food, waste, and pulp and paper Detailed examples, including the world’s largest new DAF plant ever built – Croton, NY water treatment plant A single volume entirely devoted to DAF for drinking water clarification Coverage of conventional and pre-treatment processes SI and conventional units throughout

Physicochemical Treatment Processes
