The analysis and design of today's water and wastewater treatment
plants involve evaluation of individual treatment processes
and assessment of system-wide hydraulic performance. The majority
of the existing literature and training opportunities for engineers
and operators addresses the treatment (process) aspect, but
fails to adequately cover overall plant hydraulics. This, unfortunately,
can lead to serious problems, because the two aspects of design
are inseparable. Treatment objectives cannot be met if the plant
does not function properly from a hydraulics perspective.
The maintenance of sufficient hydraulic head (i.e., energy)
throughout a plant is a principal concern. Proper evaluation
of head in treatment facilities requires information on flow
quantities, often based on population statistics, and basic
knowledge of concepts involving flow through pressurized pipes
and open channels, flow measurement and control devices, and
pumping systems. It also takes an understanding of how each
of these elements interacts with the others and with treatment
units.
Comprehensive Water and Wastewater Treatment Plant Hydraulics
Handbook for Engineers and Operators begins with an introduction
to treatment plant hydraulics (Chapter 1) that orients the
reader to the field of study and introduces fundamental properties
and principles that are used in plant analysis. Chapters 2
covers flow through pressurized conduits and presents methods
for evaluating flow of non-Newtonian fluids (e.g., sludge),
while Chapter 3 covers flow through open channel systems.
The tools presented in these two chapters provide a basis
for the evaluation of head variability through any flow system.
Chapter 4 covers flow through measurement and control devices,
including orifices, venturis, manifolds, weirs, flumes, and
others. This chapter also discusses spatially-varied flow
in distribution and collection channels and briefly introduces
concepts related to hydraulic mixing. Chapter 5 covers pump
hydraulics and includes discussions on various types of pumps
and methods to be used in their selection. Finally, Chapter
6 presents guidance on plant layout, location, and capacity
and outlines special methods for evaluating flow through the
various treatment units. Moreover, the chapter brings together
the various concepts discussed throughout the book and, thus,
serves as an overall guide for a comprehensive evaluation
of treatment plant hydraulics.
Comprehensive Water and Wastewater Treatment Plant Hydraulics
Handbook for Engineers and Operators is an advanced comprehensive
reference on the hydraulic analysis and design of water and
wastewater treatment facilities. A working handbook for engineers,
operators, students and practitioners, it covers both the
practical and theoretical aspects of plant hydraulics. It
brings together the principles of proper hydraulic design
and characterization of treatment facilities, and presents
them in a manner that can be easily understood. And with more
than 100 solved problems, special emphasis is placed on the
application of these principles. As such, it is an invaluable
reference for the study and practice of treatment plant design.
“Another excellent book from
MWH Soft. A practical, informative, working engineering reference
that covers the principles of proper hydraulic design and
characterization of treatment plant facilities for improved
performance and reliability. It’s great!”
-- Jeffrey Pecenka, PE, Supervising Engineer
and GIS/Modeling Specialist, Cheyenne Board of Public Utilities,

"Exceptionally practical and comprehensive. Its 'to the
point' style provides a clear roadmap for grasping and mastering
the principles and concepts of treatment plant hydraulics.
This is a must read for new engineers and a valuable reference
for our professionals.”
