Biological Wastewater Treatment

Written by experts in the field, the thoroughly updated 3rd Edition of Biological Wastewater Treatment covers commonly used and emerging suspended and attached growth reactors. Drawing on their extensive academic and industrial experience, the authors discuss combined carbon and ammonia oxidation, activated sludge, biological nutrient removal, aerobic digestion, anaerobic processes, lagoons, trickling filters, rotating biological contactors, fluidized beds, and biologically aerated filters to provide a comprehensive understanding of the field of biological wastewater treatment. They integrate the principles of biochemical processes with applications in the real world, communicating approaches to the conception, design, operation, and optimization of biochemical unit operations in a comprehensive yet lucid manner. Imparts a theoretical and quantitative understanding of biochemical operations, specifically the kinetics and stoichiometry of major reactions Employs mathematical models, such as the IWA/IAWQ Activated Sludge Models and biofilm modeling, to illustrate how bioreactor configuration affects performance in suspended and attached growth systems Presents biochemical operations as integrated systems in which carbon oxidation, nitrification, denitrification, and phosphorus removal are potential reactions and parallel events, emphasizing the engineer’s role in determining which events dominate Furnishes process descriptions as well as details affecting the design, operation, and performance of suspended and attached growth bioreactors in a step-by-step fashion while employing practical constraints to ensure system viability in the real world Reveals the future of bioreactors in the removal of xenobiotic organic chemicals from wastewater Click here to read and share material related to this title on the IWA WaterWiki.
