Preface
This book has been written to help professionals, students, and lay people identify
the increasing number of terms in the fields of environmental engineering and
science.
More than 8000 terms, acronyms, and abbreviations applying to wastewater,
potable water, industrial water treatment, seawater desalination, air pollution, incin-
eration, and hazardous waste remediation have been defined.
The most unique feature of this book is the inclusion of more than 3000 trade-
marks and brand names. Many of these commercial terms for proprietary products
or processes are so common or descriptive that they have fallen into general use.
This confusion is compounded by the fact that many terms contain similar prefixes
(e.g., bio-, enviro-, hydra-, hydro-, etc.) and it is often difficult to tell them apart.
This book originates from
Screening Equipment Handbook,
first published in
1988, whose glossary contains a list of screening-related trademarks and brand
names along with their company affiliation. Even though that list was relatively
short, a surprisingly large number of companies had come and gone or changed their
names through mergers or acquisitions. This led to an expanded directory entitled,
The Dictionary of Water and Wastewater Treatment Trademarks and Brand Names,
published in 1991, and which contained 1200 commercial terms.
The Concise Dictionary of Environmental Engineering
followed in 1996. In
addition to the 2200 commercial terms, it was further expanded to include 3000
generic environmental engineering terms. Shortly after it was published, the envi-
ronmental equipment manufacturing industry began a consolidation led by USFilter,
Waterlink, Baker Hughes, ITT, F.B. Leopold, and others that has resulted in changes
to 43% of the terms included in the 1996 edition.
During the research for this book, many other books, magazines, dictionaries,
glossaries, buyer’s guides, catalogs, brochures, and technical papers were reviewed
to locate new terms and their definitions. Although there are too many references
to list, I would like to acknowledge the help of these publications and their authors.
In addition to technically reviewing this book, John B. Tonner was especially
helpful with his suggestions, advice, research assistance, and computer wizardry.
Regardless of when I would call, John was always available to help. His
www.world-
wide-water.com
Web site also proved to be a valuable research tool.
I would like to acknowledge the libraries that were used in my research. They
include the M.D. Anderson Library at the University of Houston, the Helen Hall
Library in League City, Texas, the Houston Public Library Central Branch, and the
library at King Fahd University of Petroleum and Mining in Dhahran, Saudi Arabia.
I also recognize USFilter and Alfa-Laval for their support.
I’m grateful for the assistance of the many friends and colleagues who suggested
new terms and challenged old ones, helped with definitions, provided encouragement,

or assisted in the book’s production. Some of these people include Robert W. Brown,
Gordon Carter, Bill Copa, Chad Dannemann, Jim Force, Jack Gardiner, Duane
Germenis, Stacie Jones, John Meidl, Mack Moore, Chad Pankratz, Bill Perpich,
Barb Petroff, Jim Symons, Mark Wilson, and Joe Zuback.
Like the first edition, published in 1996, much of my work on this book took
place while traveling; the rest was done in the evenings and weekends. I would never
have been able to finish without the continued patience and support of my wife,
Julie, and our children, Chad, Sarah, Mike, and Katie.
This book is dedicated to my wife, Julie Lynn Pankratz, and our grandson,
Gabriel R. Suarez, who was born the same day this book was completed.

Introduction
This dictionary contains terms used in the fields of environmental engineering and
environmental science, and the definitions provided relate to their use in an envi-
ronmental context only.
The commercial terms represent company brand names or trademarks, and have
been italicized to differentiate them from the technical terms in general usage.
Whenever appropriate, the use of ™ or
®
has been included following the name of
the entry, although terms may be registered trademarks even though they do not
include either symbol. It is also possible that some of the entries listed as trademarks
may not be registered or properly used by the manufacturers listed in connection
with them.
Brand names and trademarks often evolve and take different forms. Variations
in the use of capitalization, hyphens, or symbols often occur over time. The repre-
sentation of the words included in this book reflects the latest version seen in use
and are assumed to be the preferred form.
Commercial acronyms are included if they are registered trademarks or com-
monly used abbreviations of company names. Nonregistered product model numbers
and trademarks that are the same as the name of a company are not always included.
Many definitions were extrapolated from stories, advertisements, or product bro-
chures and were not directly corroborated by the company listed as being responsible
for the term.
The company name included in the definition of a commercial term usually
represents the company that manufactures that particular product or process. In some
cases, the listed company may only market, distribute, or license the product.
In several instances, the same brand name has been listed more than once to
describe different products or processes from different companies. The author is
unaware of any dispute involving these cases and is simply reporting that the
companies identified have used the term for the product described. In some cases,
the term may be dormant, obsolete, or no longer available from the company listed.
Company addresses, phone numbers, and e-mail addresses listed in the Manu-
facturer’s Directory were confirmed over a period of several years. Some contact
information may have changed, especially with the recent telephone area code
changes in many parts of the U.S. Readers are cautioned that an incorrect phone
number, address, or e-mail address does not mean that a company is no longer in
business.
There are a few cases where a company whose name is listed in a definition is
not included in the Manufacturer’s Directory. If current contact information for a
company could not be located, the out-of-date information was not included.
Terms have been arranged alphabetically using current word processing software.
