Page 14 - Industrial Wastewater Treatment, Recycling and Reuse

Preface xiii

from biomass) that may be useful for industrial wastewater treatment, in gen-
eral, and phenolic wastewater treatment, in particular, with elaborate discus-
sion on synthesis, characterization, and application.
Chapters 9 through 11 describe the use of polymeric materials such as
membranes for wastewater treatment in various advanced forms—both in
materials as well as applications. In this regard, Chapters 9, 10, and 11 spe-
cifically highlight industrial wastewater treatment issues and applications of
newer methodologies with specific industry examples.
Chapter 12 describes process simulation for water systems optimization,
the subject that can complete the water management theme discussed by var-
ious contributors in this book. Case studies of possible zero liquid discharge
solutions based on evaporation technologies are presented in Chapter 13.
Chapter 14 finally summarizes the past, present, and future for industrial
wastewater treatment, recycling, and reuse. We hope that this book will stim-
ulate further work in this very important area from an industrial as well as from
a scientific point of view.
The intended users of this book are chemical and environmental engi-
neers working in chemical and petroleum industries and industrial R&D
laboratories as well as chemical engineering scientists/research students
working in the field of wastewater treatment. Some prior background in
separation processes and industrial practices is assumed. The material
included in this book may be used in several ways and at various stages of
designing of wastewater treatment plants as well as in fundamental research
projects on understanding and developing various technologies for water
treatment. It may also be used as a basic resource of methodologies for waste-
water treatment, recycling, and reuse and making decisions in practice. The
content may also be useful as a study material for an in-house course, oper-
ation and optimization of wastewater treatment plants, or a companion book
while solving practical problems.
There are many people to thank who made this book possible. First of all,
we would like to thank all the contributors to this book. We are also grateful
to many of our associates, colleagues, and collaborators with whom we
worked on different research and industrial projects. We would like to
acknowledge financial support from CSIR for the Indus MAGIC
(CSC123) project that allowed us to undertake our work on wastewater
treatment and develop this book. Dr. Bhandari would like to express his pro-
found gratitude to Professor V. A. Juvekar for being a constant source of
inspiration for him in research. Many of our colleagues and students have
contributed to this book in different ways. In particular, Dr. (Ms.) Laxmi
