bookshelf Air Pollution Experiments for Junior and Senior High School Science Classes. Edited by Donald C. Hunter and Henry C. Wohlers. 64 pages. Air Pollution Control Association, 4400 Fifth Ave., Pittsburgh, Pa. 15213. 1969. $1.00 (in quantities of I O or more, 50 cents), paper. Aiming to arouse in secondary school students an acute zwareness of air pollution and its effect oil their lives, as well as an interest in the field of air pollution control as a possible career, the editors include 19 experiments in the publication. Object, suitability and usefulness, theory and background, equipment, and procedures are given for each experiment. Experiment titles include: Effect of air pollution on dyed fabrics: detection and measurement of atmospheric carbon monoxide, and effect of SO, on vegetation. Sludge Dewatering.

CLEAN COOL. ABSORB gases for Industrial Air Pollution Control Impinjet Wet Scrubbers provide a simple, highly effective way to simultaneously clean, cool and absorb gas stream contaminants. The secret is in our scrubber's perforated plate design which uses a unique impingement baffle above each individual hole. Jet-swirl interaction of gas and liquid create tiny high-velocity droplets that thoroughly scrub even the dirtiest process streams. What's more, this combination of minute droplets and high relative velocity permits using low pressure drop across the scrubber. You receive not only high scrubbing efficiency but use less power to achieve it. This cuts operating costs to a minimum. For an efficient solution to a wide range of everyday industrial air pollution problems, call your Sly Field Engineering Representative. Or-contact our factory direct. And when you do, ask for Scrubber catalog 151.

I Because filter bags of N O M E X ~ : nylon are designed to operate continuously at temperatures up to 425OF. This can result in an increase in filtration capacity and a decrease in operating costs. To find out all about it-and the amazing high-temperature flex and abrasion resistance of NOMEX -send the coupon to: Du Pont Company, NOMEX Marketing, Wilmington, Delaware 19898. We'll send you case histories, a list of bag manufacturers and technical information.
