Intensifying Activated Sludge Using Media-Supported Biofilms will
be of interest to practicing wastewater treatment process
designers, along with those seeking more compact and
energy-efficient wastewater treatment options. The advantages of
Moving Bed Biological Reactor (MBBR)-based hybrid processes are now
well-established in practice, leading to their increased use in the
field. Membrane Aerated Biofilm Reactor (MABR)-based hybrid
processes are much newer and offer further systematic process and
energy advantages. This book examines the evolution of hybrid
technologies as well as the potential for continued improvement of
biological wastewater treatment techniques. Features: Reviews
current approaches for intensifying biological wastewater treatment
processes and their mechanistic bases. Examines hybrid suspended
growth/biofilm-based wastewater treatment processes, including the
newly-developed MABR-based processes, and their unique dynamic
performance characteristics. Presents a novel method for
characterizing the performance and process intensification
advantages of hybrid processes. Provides guidance for simulating
the performance of hybrid processes, including oxygen transfer in
MABR hybrid processes.
The most common activated sludge operating problems causing poor
plant performance are related to solids separation. Especially
common are bulking and foaming. Without a proper scientific
foundation to support the efforts of wastewater treatment plant
management, many attempts to thwart bulking and foaming have
failed. Manual on Solving Activated Sludge Bulking, Foaming, and
Other Solids Separation Problems provides the critical scientific
and practical underpinnings needed to understand and combat these
problems. The third edition of this flagship text is a
comprehensive, concise guide to the microbiological and technical
aspects of controlling all types of solid separation problems. The
scientific theory is applied to real-world scenarios, greatly
increasing the number of real-world examples of successful control
methods. New information is also included on filamentous organism
growth and its application in the control of sludge bulking and
foaming. Now plant operators, regulators and wastewater engineers
have a complete guide for battling these formidable design and
operating problems.
Following in the footsteps of previous highly successful and useful
editions, Biological Wastewater Treatment, Third Edition presents
the theoretical principles and design procedures for biochemical
operations used in wastewater treatment processes. It reflects
important changes and advancements in the field, such as a revised
treatment of the microbiology and kinetics of nutrient removal and
an update of the simulation of biological phosphorous removal with
a more contemporary model. See what's new in the Third Edition: A
chapter devoted to the description and simulation of anaerobic
bioreactors Coverage of applications of submerged attached growth
bioreactors Expanded discussion of modeling attached growth systems
Increased information on the fate and effects of trace contaminants
as they relate to xenobiotic organic chemicals A chapter on
applying biochemical unit operations to design systems for greater
sustainability The book describes named biochemical operations in
terms of treatment objectives, biochemical environment, and reactor
configuration; introduces the format and notation used throughout
the text; and presents the basic stoichiometry and kinetics of
microbial reactions that are key to quantitative descriptions of
biochemical operations. It then examines the stoichiometry and
kinetics used to investigate the theoretical performance of
biological reactors containing microorganisms suspended in the
wastewater. The authors apply this theory to the operations
introduced, taking care to highlight the practical constraints that
ensure system functionality in the real world. The authors focus on
further biochemical operations in which microorganisms grow
attached to solid surfaces, adding complexity to the analysis, even
though the operations are often simpler in application. They
conclude with a look to the future, introducing the fate and
effects of xenobiotic and trace contaminants in wastewater
treatment systems and examining how the application of biochemical
operations can lead to a more sustainable world.
