The Ecosystems Research Center (ERC) was established at Cornell U ni versity in October 1980 by the Environmental Protection Agency (EPA) with the goals of: 1. Identifying fundamental principles and concepts of ecosystems sci ence and the determination of their importance in understanding and pre dicting the responses of ecosystems to stress, the description of the basic mechanisms that operate within ecosystems, and an examination of the stability of ecosystem structure and function in th...

Produced Water Treatment Field Manual presents different methods used in produced water treatment systems in the oil and gas industry. Produced water is salty water that is produced as a byproduct along with oil or gas during the treatment. Water is brought along with the oil and gas when these are lifted from the surface. The water is then treated before the discharge or re-injection process. In the introduction, the book discusses the basic terms and concepts that describe produced water...

The MBR Book covers all essential aspects of membrane bioreactors in water and wastewater treatment, including the working principles of MBR technologies. The book aims to separate science from engineering, in an attempt to avoid confusion and to help readers understand the ideas of MBR. The text is divided into five chapters; the membrane and biological aspects are discussed in chapter 2 along with scientific studies. The third chapter covers the design, operation, and maintenance of MBR,...

For historical and socio-economic reasons, the countries of the southern Black Sea region are facing mounting and apparently intractable problems in managing their solid waste, with increasingly serious implications for public health and quality of life, as well as the wider socio-economic development of the region. Hitherto, no comprehensive, systematic study of the problem seems to have been conducted, to determine the underlying causes and suggesting how it might be alleviated in social...

This book presents a variety of policy adoption methods, irrigation scheduling, and design procedures in micro irrigation engineering for horticultural crops. The chapters range from policy interventions to applications of systems for different crops and under different land conditions. Compiling valuable information and research, the book is divided into three main sections:Policy Options: Drip Irrigation Among AdoptersIrrigation Scheduling of Horticultural Crops

Colloid and Interface Chemistry for Water Quality Control provides basic but essential knowledge of colloid and interface science for water and wastewater treatment. Divided into two sections, chapters 1 to 8 presents colloid chemistry including simple history and basic concepts, diffusion and Brown Motion, sedimentation, osmotic pressure, optical properties, rheology properties, electric properties, emulsion, foam and gel, and so on; chapters 9 to provides interface chemistry theories inc...

Dredged Material and Mine Tailings are two of the same thing once they are deposited on land: they must be safe-guarded, wash-out must be prevented, and they must be protected by a plantcover. This comprehensive treatise covers both important aspects of their management: In Chemistry and Biology of Solid Waste the principles and assessment are scientifically studied and discussed, while Environmental Management of Solid Waste turns to the prac...

This book provides essential background knowledge on a wide range of hydrological processes governing contaminant transport from soil to surface water across a range of scales, from hillslope to watershed. The mathematical description of these processes is based on both well-known and unique analytical solutions of different initial and boundary problems (primarily using methods from the kinematic wave theory and the reservoir/lumped-parameter concept), supported by numerical modelling stu...

India has been traditionally well-endowed with large freshwater reserves, but increasing population, urbanization and agricultural growth in recent decades are causing overexploitation of surface and groundwater. As consumption of water grows, wastewater increases significantly and in the absence of proper measures for treatment and management, is polluting existing freshwater reserves. As a result, water pollution has emerged as one of the nation’s gravest environmental threats.Th...

Living in biofilms is the common way of life of microorganisms, transiently immobilized in their matrix of extracellular polymeric substances (EPS), interacting in many ways and using the matrix as an external digestion and protection system. This is how they have organized their life in the environment, in the medical context and in technical systems – and has helped make them the oldest, most successful and ubiquitous form of life.In this book, hot spots in current biofilm resear...

This thoughtful book provides a much-needed look at the vulnerabilities and security of our nation's water sources. Written as a result of 9/11 and in response to the critical needs of water/wastewater plant managers, plant engineers, design engineers, and utility managers, it addresses the need to incorporate security upgrades in existing facility systems and careful planning in all new construction sites.Each chapter provides professional guidance on designing, operating, maintai...
