Project Summary
Fourth Conference on Advanced
Pollution Control for the Metal
Finishing Industry (Proceedings)
The Fourth EPA/AES Conference on
Advanced Pollution Control for the
Metal Finishing Industry was held in
Lake Buena Vista, Florida, January 18-
20, 1982. This broad-scoped collo-
qgium was jointly designed by the
American Electroplaters' Society and
the Nonferrous Metals and Minerals
Branch, Industrial Environmental Re-
search Laboratory, U.S. Environmental
Protection Agency. The primary objec-
tive of this Conference was to continue
the dialogue established at the First
EPA/AES Conference (1978) and
strengthened at the Second and Third
EPA/AES Conferences (1979 and
1980, respectively) between key mem-
bers of the EPA and the metal finishing
industry. The proceedings of this Fourth
Conference reflect the primary points
of the gathering: the status of EPA's
wastewaterand solid waste regulations,
and both EPA's and industry's efforts to
effectively address the ramifications of
these regulations. Special sessions of
the Conference were devoted to metal
finishing solid waste, practical pollution
control alternatives, recovery technol-
ogy, emerging technologies, and inno-
vative alternatives. The proceedings
contain 21 papers reporting on this
work.
This Project Summary was developed
by EPA's Industrial Environmental Re-
search Laboratory, Cincinnati, OH, to
announce key findings of the research
project that is fully documented in a
separate report of the same title (see
Project Report ordering information at
back).
The keynote address of the conference
was delivered by Bruce Barrett, the
USEPA's Acting Assistant Administrator
for Water, who discussed a broad range
of topics, including water quality stan-
dards regulations.
Since attendees at the first, second,
and third conferences placed the greatest
emphasis on wastewater and solid waste,
the initial segment of the Fourth Confer-
ence was structured to provide attendees
with a detailed understanding of the
potential impact of current and future
regulations in these two important envi-
ronmental areas. Key officials, represent-
ing EPA's water and solid waste regula-
tory offices, described the procedures by
which the Agency prepares and promul-
gates regulations having a direct impact
on metal finishers. Titles of presentations
from this segment were "Status of Efflu-
ent Guidelines for the Metal Finishing
Industry and the General Pretreatment
Regulations," and "Status of EPA's Haz-
ardous Waste Program."
The second segment, entitled "Solid
Waste," provided the Conference atten-
dees with an overview of the solid waste
regulations and the delisting procedure.
Descriptions of technical and administra-
tive difficulties and solutions for metal
finishing solid waste were also presented.
Presentations included "RCRA Delisting
Procedures and a Regulatory Overview,"
"Determination of the Relationship Be-
tween Plant Operating Conditions and
Wastewater Sludge Leachability," "Out-
look for New Hazardous Waste Manage-
ment Technology," "Segregated Neutral-
ization for Treatment of Concentrated
Aluminum Finishing Wastes," "Haz-
ardous Waste Treatment Facility Siting
Methods, Concerns and Progress," and
"Disposal: What Does It Really Cost?"
Since numerous industrial plants are
currently attempting to comply with vari-
ous air, water, and solid waste regula-
tions, the third and fourth segments of
the Conference discussed practical cur-
-------
rent solutions to major pollution problems.
A majority of the presentations from these
two segments were given by industrial
participants who are faced with the
burden of regulatory compliance. The
third segment, "Practical Alternatives for
Pollution Control," consisted of the follow-
ing presentations: "Energy, Environmen-
tal and Safety Benefits Through Computer
Controlled Curing Oven Processes," "Oily
Wastewater Treatment by Electrochem-
ical Techniques," "Cross Flow Filtration
Technology for Metal Finishers," and
"The Application of Ion-Exchange and
Modified Rinsing Procedures to Minimize
Treatment Costs." The fourth segment
focused on recovery technology for metal
finishing wastewater. The titles of the
presentations from this session included
"Recovery of Acid Etchants at Imperial
Clevite, Inc.," "Recovery and Electro-
chemical Technology," "Some Successful
Applications of Electrodialysis," and
"Electrolytic Metal Recovery Comes of
Age."
"Emerging Technologies and Innovative
Alternatives" was the title of the fifth
segment. Presentations described new
developments that could eventually solve
key environmental problems. This final
segment was comprised of four presenta-
tions: "New Developments for the Treat-
ment of Wastewater Containing Metal
Complexers," "Batch Hydrolysis System
for the Destruction of Cyanides in Electro-
plating Effluents," "Renovation of Electro-
plating Rinse Waters with Coupled-Trans-
port Membranes," and "The Application
of Donnan Dialysis to Electroplating
Wastewater Treatment."
An evening session entitled "Regula-
tory Reform—An Open Forum Discus-
sion" was also conducted. Panel members
representing EPA, industry, and the
Natural Resources Defense Council indi-
vidually provided opening remarks
focused at regulatory reform. The panel
then opened the floor to a free discussion
in order to permit all attendees to com-
monly and openly discuss the topical
subject as well as other related environ-
mental concerns. Since these discussions
were informal in nature to allow for a
more open dialogue, they are not included
in the proceedings.
These proceedings are published in
order that the material presented at the
Conference can benefit as many people
as possible interested in solving the
intricate problems inherent to metal
finishing processes. These proceedings
contain the presentations made by repre-
sentatives of various EPA regulatory
groups affecting the metal finishing indus-
try, as well as presentations by parties
actively addressing research and devel-
opment in this same industrial area.
The conference was co-sponsored by the U.S. Environmental Protection Agency
and the American Electroplaters' Society, Winter Park. FL 32789.
