The Bag Filterhouse for Oil-Fired Power Plants

This Report, published as Informative Report No. 7 of the Air Pollution Control Association’s TI-5 Public Utilities Committee, began to move through the 14 step approval procedure of APCA’s Technical Council in February 1964 Comments made by members of the Technical Council were considered in the preparation of the final report. It is now published as representing the best thinking of the Association. It is an extremely timely and informative report.     

Removal of Exhaust Odors from Solvent Extraction Operation by Activated Charcoal Adsorption

This report, published as Technical Data Sheet No. 1 of the Air Pollution Control Association’s TA-7 Odor and Gas Treatment Committee, has been in the 14 step approval procedure of APCA’s Technical Council and Board of Directors for over two years. The Committee is attempting a new departure in this report which would be reflected in future reports. It has attempted to write a brief summary of a typical case history in a concise fashion on one sheet. Comments made by members of the Technical Council and Board of Directors were considered in the preparation of the final report. It is now published as representing the “best thinking of the Association.”     

A Successful and Productive Year

It is gratifying to report that 1975-1976 has been another year of increased activity for the Air Pollution Control Association, and various indicators are positive compared to previous years. Membership has increased, attendance at meetings has increased, we have a substantial surplus to report, there is increased activity in membership interest and in our overall activity. Public affairs involvement has increased somewhat, as have our international activities. Local sections and technical committees have expanded their scope of productive involvement. Clearly, APCA has had a successful and productive year.     

Annual Meeting Summary June 11-16, 1967 Cleveland,Ohio

The 60th Annual Meeting of the Air Pollution Control Association is now, physically, a thing of the past. But memories of the meeting and the information learned there will remain with us.

This 14-page summary will provide a permanent record of the meeting. It consists of the keynote address, the president’s message, the executive secretary’s report, a report on the International Union of Air Pollution Prevention Associations, significant news stories, and three pages of photos.     

Consultant Guide/1977

The Journal of the Air Pollution Control Association presents its eighth directory of air pollution control consultants. This 13-page guide lists individual consultants and firms who have indicated a capability in this field by responding to a questionnaire published in the Journal.

The Consultant Guide is now a computer based program and has a different format than Guides prior to 1976. The basic change is that areas of competence are no longer coded but are shown as categories within five geographical regions. And any certifications granted by the American Academy of Environmental Engineers (AAEE), American Board of Industrial Hygiene (ABIH) and the Board for Certified Consulting Meteorologists (BCCM) are shown adjacent to the phone number in the alphabetical listing.

The Air Pollution Control Association makes no representation regarding the competence of the consultants listed nor does it accept any responsibility for their performance as consultants.     

Consultant Guide/1974

The Journal of the Air Pollution Control Association presents its fifth directory of air pollution control consultants. This 12-page guide lists individual consultants and firms who have indicated a capability in this field by responding to a questionnaire published in three consecutive issues of the Journal. The listing gives corporate names, addresses and phone numbers alphabetically within five broad geographic areas which are shown below.

Other profile information includes coded, voluntary expressions of competence submitted by the consultants, as well as any certifications granted by the American Academy of Environmental Engineers (AAEE), American Board of Industrial Hygiene (ABIH) and the Board for Certified Consulting Meteorologists (BCCM).

Toxic Substances in the Atmospheric Environment Discussion

The Critical Review on Toxic Substances in the Atmospheric Environment was presented by Bernard D. Goldstein at the 76th Annual Meeting of the Air Pollution Control Association in Atlanta, Georgia. Dr. Goldstein summarized his paper, which had been published in the May 1983 issue of JAPCA. Prepared discussions presented at the Critical Review Session are reproduced here. In addition, comments made from the floor and through the mails have been formalized and are published along with closing remarks by Dr. Goldstein. Dr. Paul J. Lioy served as Moderator for the 1983 Critical Review Session.     

Consultant Guide/1979

APCA Is Thriving

Fiscal nineteen seventy three-four was another busy year for the Association. It was a year of expanded services, publications, and meetings. New initiatives on the part of the Board of Directors, the Technical Council and its committees, local APCA Sections and the Headquarters staff were undertaken. All of the statistical reports are positive, and show increased membership, pages published, advertising, meetings, and involvement of members. But of more importance, APCA is filling its role in a positive and meaningful way, and is continuing to attract persons working in the air pollution control profession to its many programs.

As most of you know by now, dues for individual members have been increased from $25 to $35 annually because of the continued inflation in postage, paper, and cost of doing business.     

Report from the Symposium on Air Quality Criteria

Neither time nor space permitted full reporting of the Symposium on Air Quality Criteria, held June 4-5, 1968, in New York City.

Published here are excerpts from, or author’s abstracts of, the eight principal papers presented at the Symposium.

Not included are the prepared discussions which followed the delivery of the papers.

A full proceedings, including prepared discussions, general discussions, and summation, will be published in the September issue of the Journal of Occupational Medicine, 55 E. Washington Street, Chicago, Illinois 60602.

The Sheet Metal and Air Conditioning Contractors' National Association, Inc. has recently published standards for round industrial duct construction which are intended for use by designers of air pollution control and industrial ventilation systems. These standards provide a simple 3-step procedure for the selection of material gage, reinforcement systems, and connections based on clearly defined design parameters.

Apca Activities Continue to Show Growth and Expansion

The activities and accomplishments of the Air Pollution Control Association during 1974-1975 continued to show growth and expansion, although there was a decline in membership. We have a financial surplus to report in spite of the fact that our publications program was plagued with inflationary price increases in paper, printing and distribution.     

Practical dissolved-air flotation experience

In this report the performance of the Bayer Flotation Technology BayFlotech? is demonstrated by comparing process data with figures published by the German Deutsche Vereinigung fur Wasserwirtschaft, Abwasser und Abfall e.V. (ATV) and Verband Deutscher Maschinen u. Anlagenbau e.V. (VDMA) associations. In addition experience gained under plant operation is described. Inter alia the relation between the air/solid dosage rate and the specific solids loading is discovered. It was found that the specific air dosage can be decreased with increasing solids loading rates: whereas the specific air dosage is up to 35 l/kg TSS at solids loading 95%) for every compared situation. Finally we report on the newly developed 'phasemixer', which allows high water saturation rates (>95%) and preventing lather.     

Control of Atmospheric Emissions From Petroleum Storage Tanks

Informative Report No. 2, prepared by the TI-3 Petroleum Committee of the Air Pollution Control Association, deals with the control of hydrocarbon vapor emissions from petroleum storage tanks. The report presents the theory of evaporation loss from liquids, describes emission control equipment and its maintenance, and outlines techniques used to estimate the magnitude of and to reduce emissions.
