Unit Operation of Sanitary Engineering - Rich pdf

PREFACE i x
ing would serve to familiarize
the student with the notation, making
available to him much of the literature in the process engineering field.
Such accomplishment would enable him to apply to his field tools
developed in allied engineering fields.
In conclusion, it must be emphasized that this book is not a treatise.
Rather, it is a textbook dealing only with one facet of sanitary engineering—the
design of unit operations. Basic sanitary science, analytical
procedures, and unit chemical and biological processes, although of equal
importance, are not the concern of this textbook. Although empirical
design is still the rule in practice, the book has been oriented toward
rational design.
In the words of T. R. Camp: x
It is the duty of engineers ... to place their analyses and design on as rational
a basis as can be obtained. If sanitary engineers do not follow this philosophy
generally, in due time the business of designing plants will be taken over by
more competent experts.
The material presented herein was taken from many sources, all of
which are acknowledged. I can take credit only for bringing the information
together in an attempt to make it more accessible to the sanitary
engineering profession.
Acknowledgment is made with thanks to the valuable assistance given
by many of my students and colleagues. Special acknowledgment is
made to Mr. R. 0. Matthern, both student and colleague.
