Available in PDF, EPUB and Kindle. Book excerpt: Biological Phosphate Removal from Wastewaters contains the proceedings of an International Association on Water Pollution Research and Control Specialized Conference held in Rome, Italy on September 28-30, 1987. Contributors review advances that have been made in the removal of biological phosphates from wastewaters, both at the fundamental scientific level and in the practical application of the process. Topics range from the fundamental microbiology and biochemistry of the enhanced biological removal of phosphate to the practical full-scale plant experiences with phosphorus removal and sludge handling from such processes. This text is comprised of 43 chapters; the first of which describes the utilization of polyphosphate as an energy reserve in Acinetobacter sp. and activated sludge. Attention then turns to metabolic control in polyphosphate-accumulating bacteria and its role in enhancing biological phosphate removal. The biochemistry and energetics of biological phosphorus removal are also considered. The next section is devoted to process modeling and includes chapters that explore the kinetics of biological excess phosphorus removal; factors affecting anaerobic stabilization during biological phosphorus removal; and the behavior of magnesium in biological phosphate removal. In the next section, bench/pilot-scale studies are presented; one of which investigated the reduction of returned phosphorus from a sludge treatment process. The book concludes with a discussion on phosphate removal mechanisms and pilot- and full-scale experiences. This book will be of interest to students, practitioners, and policymakers in water pollution control.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: USEPA is currently establishing requirements for minimizing discharges of nutrients in the nation's receiving waters. The enhanced biological phosphorus removal (EBPR) process is based on the poly-phosphate accumulating organisms' (PAOs unique features of luxury phosphate uptake during aerobic conditions and phosphate release in anaerobic conditions. The objective of this study was to investigate the EBPR process at three different levels: full scale and pilot scale level, micro level and molecular level. Two Cincinnati MSD wastewater water treatment plants(WWTPs), the Mill Creek Plant and the Sycamore Creek Plant, as well as a WWTP in Butler County, were chosen to be the research sites. Water qualities were monitored along each treatment process, and activated sludge samples were taken from each plant for micro and molecular level studies. Pilot plants were operated at each plant to evaluate alternative operation modes to achieve the optimum phosphorus removal rate. Operation and design suggestions were made based on the full scale investigation and were confirmed through the pilot plant study. A phosphate-selective microelectrode was developed in this research and used to obtain P-profiles across activated sludge flocs. This cobalt-based phosphate ion-selective microelectrode has a tip diameter of 5︢︣20 þm and shows good selectivity towards all three forms of ortho-phosphate ions, H2PO4-, HPO42-, and PO43-. A calibration curve at pH 7.5 with a slope of 31.5 mV per decade change of concentration and a R2 value of 0.99 was obtained. A P peak was found in each P profile of flocs taken from the anaerobic sections at the different treatment plants. This phenomenon could be caused by the DO profile present (lowest DO at the center) or by mass transfer resistance. Fluorescent in situ hybridization (FISH) was used as a molecular biological tool to show the existence of PAOs in the activated sludge. Three oligonucleotide probes used in this study-PAO651, PAO846 and Rhc0439-were purchased from the DNA core-lab at the University of Cincinnati. The images showed the existence of PAOs at the Mill Creek and the Butler County plant.

This book was released on 2004-01-01 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simultaneous biological nutrient removal (SBNR) is the removal of nitrogen and/or phosphorus in excess of that required for biomass synthesis in biological wastewater treatment systems where there are no defined anaerobic and/or anoxic zones. The hypothesis is that one or more of three mechanisms is responsible within individual systems: variations in the bioreactor macroenvironment created by the mixing pattern, gradients within the floc microenvironment, and/or novel microorganism activity. Understanding of the mechanisms of SBNR can be expected to lead to improved efficiency and reliability in its application. Preliminary work documented SBNR in 7 full-scale OrbalTM closed loop bioreactors. A batch assay demonstrated that novel microorganism activity was of little importance in SBNR at the three plants tested. While the floc microenvironment likely plays an important role in nitrogen removal in such plants, it cannot explain phosphorus removal. A computational fluid dynamics (CFD) model was developed to elucidate the role of the bioreactor macroenvironment in SBNR. This is the first reported application of CFD to activated sludge biological wastewater treatment. Although the software and computational requirements limited model complexity, it still simulated the creation of dissolved oxygen gradients within the system, demonstrating that the anaerobic zones required for SBNR could occur.
