Nutrient Removal from Wastewaters


Book Description

Topics in the book include: novel processes, removal of ammonia and nitrogen, retrofitting/upgrading treatment plants for nutrient removal, and operating experiences at full-scale plants. Nutrient removal from wastewaters is a critical topic in every region. Problems can arise from domestic sewage, industrial wastewater, or rainwater runoff.

The Removal of Nitrogen Compounds from Wastewater


Book Description

This volume gives an overview of the wide spectrum of nitrogen removal processes available today. Part A gives a brief outline of nitrogen pollution sources, the global nitrogen cycle and the treatment methods; part B presents details of all biological methods for nitrogen removal; and part C describes the physico-chemical nitrogen removal methods. Design examples relating to parts B and C are given in appendices.Design equations are given in the text, but more emphasis has been placed on the profound understanding of the biological and chemical processes and the basic factors that influence these. Parameters and regression equations for a quantitive description of these factors and their influence on the key processes are presented in several tables. This feature makes the volume a very useful handbook; it will be of great value to those environmentalists who require a record of the available nitrogen removal methods from both biological and chemical viewpoints.




Environmental Impacts of Aquaculture


Book Description

The continued expansion of aquaculture – in a wide range of environments and of a growing number of species has lead to increasing demands on aquatic resources. These demands vary with the culture species, the culture method and the environmental and ecological setting. While there are many examples of efforts to mitigate detrimental environmental effects, the environment remains the ultimate constraint on the future sustainable development of this maturing industry. The relationships between the activities of aquaculture and the environment are therefore of economic importance as well as of scientific interest and, for these reasons, a large international research community has developed over the past decade. In this volume, the resultant research is synthesised and critically reviewed, providing a source of reference to the most important recent developments at research and professional level. The authors are internationally recognised authorities who have made significant contributions to their respective research areas. The first part of the volume is organised in terms of the major culture types. This is followed by chapters of general relevance to aquaculture. The volume is designed to complement Biology of Farmed Fish (eds K D Black/A D Pickering), also published in this series. It is directed at fish biologists, shellfish biologists and environmental scientists working in the academic, governmental and industrial sectors.










Developments in Environmental Modelling


Book Description

The use of models to assess water quality is becoming increasingly important worldwide. In order to be able to develop a good model, it is necessary to have a good quantitative and ecological description of physical, chemical and biological processes in ecosystems. Such descriptions may be called ``submodels''. This book presents the most important, but not all, submodels applied in water quality modelling. Each chapter deals with a specific physical process and covers its importance, the most applicable submodels (and how to select one), parameter values and their determination, and future research needs.The book will be an excellent reference source for environmental engineers, ecological modellers and all those interested in the modelling of water quality systems.
