English | 2024 | ISBN: 366266447X | 225 Pages | PDF EPUB (True) | 123 MB
This professional book deals with belt drying of sewage sludge, mainly of municipal but also of industrial origin. The wastewater treatment resulting in sludge production is briefly described. The types of sludge and their degree of stabilization is treated in depth as they have a high impact on their suitability for belt drying and the necessary exhaust air treatment. Different belt drying systems with or without condensing units and with extruding of dewatered sludge or partial recirculation of dried sludge are presented. Specific water evaporation and energy demand are tabulated for each dryer system on basis of indications of dryer manufacturers, measurements or information of dryer operators. Different sources for thermal energy are stipulated and complete systems of energy supply with internal or external usage of exhaust energy described. Occurring gas compounds in dryer exhaust air and their special features are mentioned in depth. The components and complete systems for exhaust air cleaning are discussed also in their efficiency of removal of individual odorous gas components or of total amount of volatile organic compounds. Conveying systems and storage of dewatered sludge as well as of dried sludge are described together with the related safety issues. Dryer control as well as ATEX, SIL and HAZOP issues and economic aspects are discussed briefly in individual chapters.

Lake Urmia A Hypersaline Waterbody in a Drying Climate


Free Download Lake Urmia: A Hypersaline Waterbody in a Drying Climate
English | 2023 | ISBN: 3031410521 | 545 Pages | PDF EPUB (True) | 145 MB
This book provides a holistic review of the environmental status of Lake Urmia in terms of its hydrodynamic, chemical, and ecological properties. Lake Urmia is a shallow landlocked hypersaline water body located in the northwest part of Iran, and it is known as one of the largest continental salt lakes in the world. Divided into 16 chapters, the book gathers leading experts from various scientific disciplines, and it covers past and current characteristics of the lake and traces projections on how the water quantity, quality, chemical, and ecological state of Lake Urmia Basin can develop in the future. The book outcomes are based on the analyses of the data of observations and unique models that were elaborated for the Lake Urmia system development studies. Particular attention is given to the basin drought in response to anthropogenic drivers and environmental pressures such as climate variability and climate change and their impact on the aquatic environment. The impact of water conveyance on Lake Urmia to improve the physical, chemical, and biological natural state is also discussed in this book, where an intensive and challenging observation plan in this harsh environment is combined with uniquely coupled and adopted hydrodynamical-biogeochemical models. Given its scope, the book offers an invaluable source of information for researchers, students, and environmental managers interested in the Lake Urmia environment.
