THE AUTHOR
Joseph D. Edwards, P.E., Ph.D., has worked
in industry, consulting, academia, and government.
He has implemented new industrial processes, fixed
old ones, designed and started up waste treatment
processes, determined the cause of treatment plant
upsets, assessed the impact of new production pro-
cesses on waste management activities, and devel-
oped hazardous waste reduction plans. In addition,
he has developed local limits for industrial dis-
charges, reviewed process engineering reports for
wastewater treatment systems, written permits for
industrial dischargers, developed compliance plans, conducted analysis of the
effects of discharges on municipal treatment plants, and helped to revise state
regulations regarding the discharge of dangerous waste to the sanitary sewer.
He is the co-inventor of a patented process for removing toxic organics and
metals from manufacturing wastewater.
Dr. Edwards earned a B.S. in Chemistry, a M.S. in Civil Engineering, Air
Resources, and a Ph.D. in Civil Engineering, Environmental Science and
Technology, from the University of Washington. His Ph.D. dissertation evalu-
ates the use of diffusion dialysis for the recovery of acids from spent process
solutions. He is a registered Professional Engineer in the State of Washington.
Dr. Edwards can be reached via e-mail at [email protected].
ACKNOWLEDGMENTS
Thanks to the three shops who let me share their experience in the
appendices and pilot test examples and who reviewed the text to help to ensure
that it is accurate. Thanks to the shop that provided the photograph of the sink
for the front cover.
Thanks to Rick Renaud, P.E. (Municipality of Metropolitan King County,
Metro) and Professor Mark Benjamin (University of Washington) for support-
ing this book in its proposal stage and having confidence that it could be done.
Most of all I want to thank my wife, Belle Randall Edwards, for her help
and encouragement. She read the book cover-to-cover and made many helpful
comments. She also provided much needed moral support.
