not as black as painted

DEARSIR: The Environmental Currents section of your September 1970 issue, page 718, included a short commentary on air pollution from municipal incinerators. The summary of the Arthur D. Little study on municipal incineration in this country suggested that air pollution emissions from municipal incinerators could, by the end of this century, constitute a major source of air pollution. The initial reaction of a reader, as a result of this summary, may be prejudicial against the use of municipal incineration in dealing with our solid waste problem. It is evident, however, that the application of incinerator technology for controlling diverse forms of pollution will become increasingly great in the future. In addition, the reader may infer that the relative figures for emission are based on application of present technology. While it is true that control technology for incineration can be, should be, and will be improved, it is also true that the application of existing control technologies would bring about a significant reduction of present emissions. Utilization of such technologies would also stimulate more accelerated growth in the application of incineration to replace less desirable methods of solid waste disposal. The problem, particularly with regard to municipal incinerator systems, lies not with available technology, but with its application. All too often, selections are made by bidding methods which emphasize low initial cost rather than value per unit cost. The technology exists, and is being further developed, to increase efficiencies markedly, even beyond the 90% mentioned in the Currents item, to the 95 to 99% efficiencies demonstrable in present industrial units. Governmentfunded research will stimulate studies to gain even greater efficiencies with optimum, economical cost for incinerator systems. Richard C.

fiAt.~~d-FiQCntalog This is a comprehensive compilation of information for anyone

involved in the selection and application of advanced filter media Within its pages are Mead's testing methods and complete descriptions of filter grades for general liquid filtration, laboratory liquid filtration, .and glass filter media for, both air and liquid filtration. Charts and a wealth of technical data support all descriptions. There is no better source for filter media than Mead Technical Papers, a djvision of The,Mead Corporation. If none of our standard Mead-Flo filter media fit your requirements, let us know. We'll "custom engineer" one that does. Don't hesitate to write Dick Devoe, Dept. H , for your free i (413) 243-1231.

Simplified BOD Test

Now anyone can get accurate, reliable biochemical oxygen demand water quality determinations without complicated procedures, calculations or previous training. Hach Model 2173 manometric BOD measurements compare within '5% of standard APHA dilution procedures and, at the same time, cost less to operate than other manometric set-ups used (Warburg and Sierp). The Model 2173 BOD reads directly in ranges from 0-35 ppm to 0.350 ppm. Progressive readings are easily graphed where rate data is required. And, the new compact design requires minimum incubator space. No buffers are required. The Hach Model 2173 BOD comes complete with five sample mixing bottles, mag. netic stirring bars, and all necessary accessories. Price $200 F.O.B. Ames, Iowa, U.S.A.
