Biological Phosphorus Removal Activated Sludge Process in Warm Climates


Book Description

Special Offer: Cao Ye Shi Author Set - Buy all three books together and save a total £76! Biological Phosphorus Removal Activated Sludge Process in Warm Climates presents the results of detailed research on the Enhanced Biological Phosphorus Removal (EBPR) activated sludge process under warm climate conditions (20oC - 30oC), which is part of the R & D program of Public Utilities Board (PUB) Singapore. The investigations and studies presented in this book are application-oriented, but at the same time the studies aim at an insightful understanding of the EBPR with the knowledge of the latest development in academic field. The focus points are: EBPR performance of laboratory-scale and full-scale activated sludge processes under the site conditions in warm climates The carbon competition and distribution between PAO and GAO (and denitrifiers) in the process The stoichiometry and kinetics of P-release, COD uptake in the anaerobic environment and P-uptake in the aerobic environment under different temperatures and operating conditions PAO and GAO population fractions, shift and dominance studies using FISH and batch tests The inter-relationships between the system performance, process design and the microbial community EBPR for industrial wastewater (high ratio of feed COD/P) treatment under warm climates. Together with the preceding book – Biological Nitrogen Removal Activated Sludge Process in Warm Climates – published by IWA in 2008, this book fills the gap of biological nutrient (nitrogen and phosphorus) removal in warm climates and provides unique experiences and knowledge for Process and design researchers and engineers in wastewater research, students and academic staff in Civil/Sanitation/Environment Departments, as well as Managers, Engineers and Consultants in water companies and water utilities.

Phosphorus Removal with Pickle Liquor in an Activated Sludge Plant


Book Description

Hot waste pickle liquor (ferrous sulfate) as an iron source was successful in precipitating phosphorus from solution in a 115 mgd East Plant of Milwaukee's Jones Island Activated Sludge Wastewater Treatment Plant. An 85 mgd section of the plant receiving the same influent was operated as a control. The East Plant with iron addition, achieved 91.3% removals (0.70 mg/1 P effluent residual), while the control West Plant removed 83.1% (1.4 mg/1 P residual). Comparison of efficiencies of purification, pH, alkalinity, and microscopic examinations of the sludge microorganism indicated that the addition of unneutralized waste pickle liquor did not adversely affect purification processes.




Aerobic Granular Sludge


Book Description

Aerobic Granular Sludge has recently received growing attention by researchers and technology developers, worldwide. Laboratory studies and preliminary field tests led to the conclusion that granular activated sludge can be readily established and profitably used in activated sludge plants, provided 'correct' process conditions are chosen. But what makes process conditions 'correct'? And what makes granules different from activated sludge flocs? Answers to these question are offered in Aerobic Granular Sludge. Major topics covered in this book include: Reasons and mechanism of aerobic granule formation Structure of the microbial population of aerobic granules Role, composition and physical properties of EPS Diffuse limitation and microbial activity within granules Physio-chemical characteristics Operation and application of granule reactors Scale-up aspects of granular sludge reactors, and case studies Aerobic Granular Sludge provides up-to-date information about a rapidly emerging new technology of biological treatment.







Design and Retrofit of Wastewater Treatment Plants for Biological Nutritient Removal


Book Description

This book presents information that can be used for the design and operation of wastewater treatment plants that utilize biological nutrient removal processes, i.e., processes that utilize biological mechanisms instead of chemical mechanisms, to remove phosphorus and nitrogen from wastewaters. The book provides: basic fundamentals, concepts, and theories; design of prefermentation units, various types of BNR systems, and secondary clarifiers; retrofitting conventional activated sludge plants; modeling considerations; and special considerations for BNR systems. It includes full-scale and pilot plant case histories, design examples, and retrofit of existing plants.




Activated Sludge and Aerobic Biofilm Reactors


Book Description

Activated Sludge and Aerobic Biofilm Reactors is the fifth volume in the series Biological Wastewater Treatment. The first part of the book is devoted to the activated sludge process, covering the removal of organic matter, nitrogen and phosphorus.A detailed analysis of the biological reactor (aeration tank) and the final sedimentation tanks is provided. The second part of the book covers aerobic biofilm reactors, especially trickling filters, rotating biological contractors and submerged aerated biofilters. For all the systems, the book presents in a clear and informative way the main concepts, working principles, expected removal efficiencies, design criteria, design examples, construction aspects and operational guidelines. About the series: The series is based on a highly acclaimed set of best selling textbooks. This international version is comprised by six textbooks giving a state-of-the-art presentation of the science and technology of biological wastewater treatment. Other titles in the series are: Volume 1: Waste Stabilisation Ponds; Volume 2: Basic Principles of Wastewater Treatment; Volume 3: Waste Stabilization Ponds; Volume 4: Anaerobic Reactors; Volume 6: Sludge Treatment and Disposal




Kinetics of Wastewater Treatment


Book Description

Kinetics of Wastewater Treatment contains the proceedings of a post-conference seminar held at the Technical University of Denmark, Copenhagen in 1978. Separating 10 papers presented in the seminar as chapters, this book begins with the conceptual basis of calcium phosphate precipitation in a denitrifying biofilm. The influence of pH and calcium ions upon phosphorus transformations in biological wastewater treatment plants; sewage treatment by activated sludge; orthokinetic flocculation of phosphate precipitates in a multicomponent reactor with non-ideal flow; and kinetics of phosphorus transformations in aerobic and anaerobic environments are then described. This text also looks into the chemical floc formation in wastewater treatment; temperature dependency of microbial reactions; the influence of some environmental factors on floc kinetics; kinetics of biological flocs; and two step precipitation of calcium phosphates.
