Download or read book Phosphorus Recovery and Recycling written by Hisao Ohtake and published by Springer. This book was released on 2018-05-25 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the engineering aspects of phosphorus (P) recovery and recycling, presenting recent research advances and applications of technologies in this important and challenging area of engineering. It highlights full-scale applications to illustrate the performance and effectiveness of the new technologies. As an essential element for all living organisms, P cannot be replaced by any other element in biochemical processes, humans ultimately rely its availability. Today, P is mostly obtained from mined rock phosphate (Pi). However, natural reserves of high-grade rock Pi are limited and dwindling on a global scale. As such, there have been increased efforts to recycle P from secondary sources, including sewage sludge, animal manure, food waste, and steelmaking slag, and so close the anthropogenic P cycle. In addition to various aspects of phosphorus covered by other literature, including chemistry, biochemistry, ecology, soil-plant systems and sustainable management, this book is a valuable and comprehensive source of information on the rapidly evolving field of P recovery and recycling engineering for students, researchers, and professionals responsible for sustainable use of phosphorus.
Download or read book Dynamics of Pond Aquaculture written by Hillary S. Egna and published by CRC Press. This book was released on 2017-12-14 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: The culmination of over a decade's worth of research by the Pond Dynamics/Aquaculture Collaborative Research Support Program (CRSP), Dynamics of Pond Aquaculture not only explains the physical, chemical, and biological processes that interact in pond culture systems, but also presents real-world research findings and considers the people who depend on these systems. This book uses data from CRSP field research sites in East Africa, Southeast Asia, Central America, and North America to present a complete picture of the pond system and the environment in which it exists. A thorough study of the principles and practices of aquaculture, the book reflects the state of the art in pond aquaculture and incorporates recent advances that have changed the science in the last decade or so. It provides a thorough review of the many methods, techniques, and ideas that comprise this complex and fascinating area of study.
Download or read book Pond Aquaculture Water Quality Management written by Claude E. Boyd and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: The efficient and profitable production of fish, crustaceans, and other aquatic organisms in aquaculture depends on a suitable environment in which they can reproduce and grow. Because those organisms live in water, the major environ mental concern within the culture system is water quality. Water supplies for aquaculture systems may naturally be oflow quality or polluted by human activity, but in most instances, the primary reason for water quality impairment is the culture activity itself. Manures, fertilizers, and feeds applied to ponds to enhance production only can be partially converted to animal biomass. Thus, at moderate and high production levels, the inputs of nutrients and organic matter to culture units may exceed the assimilative capacity of the ecosystems. The result is deteriorating water quality which stresses the culture species, and stress leads to poor growth, greater incidence of disease, increased mortality, and low produc tion. Effluents from aquaculture systems can cause pollution of receiving waters, and pollution entering ponds in source water or chemicals added to ponds for management purposes can contaminate aquacultural products. Thus, water quality in aquaculture extends into the arenas of environmental protection and food quality and safety. A considerable body of literature on water quality management in aquaculture has been accumulated over the past 50 years. The first attempt to compile this information was a small book entitled Water Quality in Warmwater Fish Ponds (Boyd I 979a).
Download or read book Innovations in Biotechnology for a Sustainable Future written by Naga Raju Maddela and published by Springer Nature. This book was released on 2021-10-23 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: This contributed volume compiles the latest improvements in the field of biotechnology. It focuses on topics that comprises industrial, environment, agricultural and medical related issues to technology and biological studies and exhibits the correlation between the biological world and the dependence of humans on it. The book is organized into five parts covering the role of biotechnology in industrial products, environmental remediation, agriculture and pharmacological agents. Ranging from micro-scale studies to macro, it covers a huge domain of agricultural biotechnology and focuses on important commercial crops (e.g. cacao and coffee), arbuscular mycorrhizal fungi, flow and distribution of phosphorus in agricultural soils in the Latin American region. Overall, the book portrays the importance of modern biotechnology and its role in solving the problems in modern day life. The book is a ready reference for practicing students, researchers of environmental engineering, chemical engineering, agricultural engineering, and other allied fields likewise.
