Instrumentation, control and automation (ICA) in wastewater treatment systems is now an established and recognised area of technology in the profession. There are obvious incentives for ICA, not the least from an economic point of view. Plants are also becoming increasingly complex which necessitates automation and control. Instrumentation, Control and Automation in Wastewater Systems summarizes the state-of-the-art of ICA and its application in wastewater treatment systems and focuses on how leading-edge technology is used for better operation. The book is written for: The practising process engineer and the operator, who wishes to get an updated picture of what is possible to implement in ...
In a world where there is a growing awareness of the possible effects of human activities on climate change, there is a need to identify the emission of greenhouse gases (GHG) from wastewater treatment plants (WWTPs). As a result of this growing awareness, governments started to implement regulations that require water authorities to report their GHG emissions. With these developments there exists a strong need for adequate insight into the emissions of N2O and CH4. With this insight water authorities would be able to estimate and finally reduce their emissions. The overall objectives of the different research programs performed by partners of the GWRC members WERF (United States of America), WSAA (Australia), CIRSEE-Suez (France) and STOWA (the Netherlands) were: To define the origin of N2O emission. To understand the formation processes of N2O. To identify the level of CH4 emissions from wastewater collection and treatment systems. To evaluate the use of generic emission factors to estimate the emission of N2O from individual plants
Activated Sludge - 100 Years and Counting covers the current status of all aspects of the activated sludge process and looks forward to its further development in the future. It celebrates 100 years of the Activated Sludge process, from the time that the early developers presented the seminal works that led to its eventual worldwide adoption. The book assembles contributions from renowned world leaders in activated sludge research, development, technology and application. The objective of the book is to summarise the knowledge of all aspects of the activated sludge process and to present and discuss anticipated future developments. The book comprises invited papers that were delivered at the conference "Activated Sludge...100 Years and Counting!", held in Essen, Germany, June 12th to 14th, 2014. Activated Sludge - 100 Years and Counting is of interest to researchers, engineers, designers, operations specialists, and governmental agencies from a wide range of disciplines associated with all aspects of the activated sludge process. Authors: David Jenkins, University of California at Berkeley, USA, Jiri Wanner, Institute of Chemical Technology, Prague, Czech Republic.
Nitrogen constitutes 78% of the Earth’s atmosphere and inevitably occupies a predominant role in marine and terrestrial nutrient biogeochemistry and the global climate. Callous human activities, like the excessive industrial nitrogen fixation and the incessant burning of fossil fuels, have caused a massive acceleration of the nitrogen cycle, which has, in turn, led to an increasing trend in eutrophication, smog formation, acid rain, and emission of nitrous oxide, which is a potent greenhouse gas, 300 times more powerful in warming the Earth’s atmosphere than carbon dioxide. This book comprehensively reviews the biotransformation of nitrogen, its ecological significance and the consequences of human interference. It will appeal to environmentalists, ecologists, marine biologists, and microbiologists worldwide, and will serve as a valuable guide to graduates, post-graduates, research scholars, scientists, and professors.
The selection of papers in this special issue of WEMS illustrates the various aspects of water and wastewater treatment and management. These papers were presented at the 2nd Young Researchers Conference held on 23-24 April 2004, at the University of Wageningen, The Netherlands. It was organised on behalf of the International Water Association (IWA) and supported by the European Symposium of Environmental Biotechnology (ESEB 2000). The IWA Young Researcher Conferences' mission is to provide young researchers in water and wastewater science, technology and management with a forum to discuss current and future environmental concerns. The conferences aim to confront environmental researchers with technologists and regulatory instances dealing with environmental quality. Moreover, the IWA Young Researchers Conferences address issues related to the development of careers in the water sector.
This volume establishes cinema as a vital force in Shanghai culture, focusing on early Chinese cinema. It surveys the history and historiography of Chinese cinema and examines the development of the various aspects affecting the film culture.
The reduction of nitrate to nitrogen by metalloenzymes is a vital step in the nitrogen cycle. The importance of this pathway has inspired efforts to understand in greater depth the mechanisms involved. This book presents and discusses the latest information on multiple aspects of denitrification. Written by recognized specialists in the field, this book describes the bioinorganic aspects and the key enzymes involved in denitrification, including their structure, function and mechanisms. Active site modelling, novel methodologies for monitoring denitrification in vivo and biotechnological methods for water treatment are discussed. The book also focusses on the environmental implications of denitrification, such nitrate accumulation and the release of nitrous oxide into the atmosphere from excessive fertiliser use. An important topic in many biological, environmental and agricultural contexts, this book will aid teaching and help bioinorganic chemists and biotechnologists gain an up-to-date picture of the science behind the denitrification process.
Shanghai in the early twentieth century was alive with art and culture. With the proliferation of popular genres such as the martial arts film, the contest among various modernist filmmakers, and the advent of sound, Chinese cinema was transforming urban life. But with the Japanese invasion in 1937, all of this came to a screeching halt. Until recently, the political establishment has discouraged comprehensive studies of the cultural phenomenon of early Chinese film, and this momentous chapter in China's history has remained largely unexamined. The first sustained historical study of the emergence of cinema in China, An Amorous History of the Silver Screen is a fascinating narrative that ill...
This book takes a cultural studies approach to analyze and account for the ways in which related to film, literature, cultural production, ideology, social change and modernity were in raised in the leftwing film movement of the 1930s.
This book constitutes the refereed proceedings of the 15th Conference on Image and Graphics Technologies and Applications, IGTA 2020, held in Beijing, China in September, 2020.* The 24 papers presented were carefully reviewed and selected from 115 submissions. They provide a forum for sharing progresses in the areas of image processing technology; image analysis and understanding; computer vision and pattern recognition; big data mining, computer graphics and VR, as well as image technology applications. *The conference was held virtually due to the COVID-19 pandemic.
