دانلود کتاب Environmental engineering and activated sludge processes: models, methodologies, and applications

"The activated sludge process is one of the most versatile and commonly used wastewater treatment systems in the world. In the past, biological wastewater treatment based in activated sludge focused on removing organic matter and suspended soils, but nowadays wastewater treatment plants need additional requirements and technology to eliminate toxic metals, odors, nutrients and pathogens. This shift means environmental engineers must build new treatment plants and retrofit old ones to optimize the waste removal processes. In this compendium, the editor, an experienced and well-published scientist in the field, has brought together articles that relate to the new requirements, organized under these topic headings: models and kinetics; process microbiology as it relates to the diversity of activated sludge; nitrogen and phosphorous removal; methane production; biofilm bioreactors. The contributors present case studies and research from eleven different countries around the world, offering a truly global and international perspective on this topic. The book is primarily intended for graduate and PhD students, but it will also be a valuable resource for environmental engineers, consultants, and other professionals who deal with activated sludge processes."-- Read more...
