Wastewater Treatment and Reuse Theory and Design Examples - Volume 2: Post-Treatment, Reuse, and Disposal by Syed R. Qasim and Guang Zhu | PDF Free Download.
VOLUME 1 Principles and Basic Treatment
VOLUME 2 Post-Treatment, Reuse, and Disposal
Over the last decade there have been rapid developments and changes in the field of wastewater treatment.
The emphasis has been on identification, detection, and removal of specific constituents; computer simulation and modeling; membrane processes; renovation and reuse of wastewater effluent; nutrients recovery, and reduction and utilization of biosolids;
energy conservation; greater understanding of theory and principles of treatment processes; and application of these fundamentals into facility design. Environmental engineers have many responsibilities.
One of the most demanding yet satisfying of these are the design of wastewater treatment and reuse facilities.
There are several books that discuss the fundamentals, scientific principles, and concepts and methodologies of wastewater treatment.
The actual design calculation steps in numerical examples with intense focus on practical application of theory and principles into process and facility design are not fully covered in these publications.
The intent of the authors writing this Wastewater Treatment and Reuse book is threefold: first, to present briefly the theory involved in specific wastewater treatment processes;
second, to define the important design parameters involved in the process, and provide typical design values of these parameters for ready reference; and third, to provide a design approach by providing numerical applications and step-by-step design calculation procedure in the solved examples.
Over 700 illustrative example problems and solutions have been worked out to cover the complete spectrum of wastewater treatment and reuse from fundamentals through advanced technology applied to primary,
secondary and advanced treatment, reuse of effluent, by-product recovery and reuse of biosolids. These examples and solutions enhance the readers’ comprehension and deeper understanding of the basic concepts.
They also serve as a good source of information for more experienced engineers, and also aid in the formal design training and instruction of engineering students.
Equipment selection and design procedures are the key functions of engineers and should be emphasized in engineering curricula.
Many practice problems with step-by-step solution provide skills to engineering students and professionals of diverse background for learning, and to master the problem-solving techniques needed for professional engineering (PE) exams.
Also, these solved examples can be applied by the plant designers to design various components and select equipment for the treatment facilities.
Thus, the Wastewater Treatment and Reuse book is a consolidated resource of valuable quick-and-easy access to a myriad of theory and practice information and solved examples on wastewater treatment processes and reuse.
This work is divided into two volumes. Principles and basic treatment processes are covered in Volume 1, which includes Chapters 1 through 10.
Volume 2 contains Chapters 11 through 15 to cover posttreatment processes, reuse, and solids disposal. Volume 1: Principles and Basic Treatment.
Chapter 1 is an overview of wastewater treatment: past, present, and future directions. Chapters 2 and 3 cover the stoichiometry, reaction kinetics, mass balance, theory of reactors, and flow and mass equalization.
Sources of municipal wastewater and flow rates and characteristics are provided in Chapters 4 and 5. Chapter 6 provides an in-depth coverage of wastewater treatment objectives, design considerations, and treatment processes and process diagrams.
The preliminary treatment processes are covered in Chapters 7 and 8. These unit processes are screening and grit removal.
Chapter 9 deals with primary treatment with plain and chemically enhanced sedimentation. Chapter 10 provides an in-depth coverage of biological waste treatment and nutrients removal processes.
Volume 2: Post-Treatment, Reuse, and Disposal. Chapter 11 covers major processes for effluent disinfection, while Chapter 12 deals with effluent disposal and reuse.
Chapter 13 is devoted to residuals management, recovery of resources, and biosolids reuse. The plant layout, yard piping, plant hydraulics, and instrumentation and controls are covered in Chapter 14.
Upgrading of secondary treatment facility, land application, wetlands, filtration, carbon adsorption, BNR and MBR; and advanced wastewater treatment processes such as ion exchange, membrane processes, and distillation for demineralization are covered in Chapter 15.

This Wastewater Treatment and Reuse book will serve the needs of students, teachers, consulting engineers, equipment manufacturers, and technical personnel in city, state, and federal organizations who are involved with the review of designs, permitting, and enforcement.
To maximize the usefulness of the Wastewater Treatment and Reuse book, the technical information is summarized in many tables that have been developed from a variety of sources.
To further increase the utility of this Wastewater Treatment and Reuse book six appendices have been included.
These appendices contain:
(a) abbreviations and symbols, basic information about elements, useful constants,
common chemicals used in water and wastewater treatment, and U.S. standard sieves and size of openings; (b) physical constants and properties of water, solubility of dissolved gases in water, and important constants for solubility and sodicity of water;
(c) minor head loss coefficients for pressure conduits and open channels, normal commercial pipe sizes, and design information of Parshall fumes;
(d) unit conversions;
(e) design parameters for wastewater treatment processes; and
(f) list of examples presented and solved in this Wastewater Treatment and Reuse book. These appendices are included in both volumes. The numerical examples are integrated with the key words in the subject index.
This gives additional benefit to the users of this Wastewater Treatment and Reuse book to identify and locate the solved examples that deal with the step-by-step calculations on the specific subject matter.
