Waste disposal
A line of packaged combustion units is easily and economically installed, and meets or exceeds various air pollution standards, the company says. Designed to take advantage of the economy and efficiency of gas firing, the units accomplish complete consumption of waste materials-which do not require preloading separation-without smoke. odor, fly-ash.

chances are OXYCAT is for you.
The closed loop High Intensity Magnetic Separator System incorporates three stages of treatment for blast furnace scrubber effluent: continuous removal of solids; continuous removal of heat; and continuous removal of chemical contaminants, the company says. Basic components of the system are the separator, heat exchanger, and chemical treatment bypass loop. The company claims that, when dumping of process water may be required, the system reduces suspended solid particulate matter to less than 40 p.p.m. Magnetic Engineering Assoc. 62

Smoke gage
The Model H G L - ~Smoke ~ Indicator continuously and instantaneously measures density of smoke by photoelectric means, according to the company. Constructed of three elements-a light source, photo unit, and meter housing-the device features three colored signal lights to denote three zones of smoke density. Green indicates clear or slight haze; yellow shows increasing density; red signals objectionable smoke. Photomation, Inc. 64 Water treatment
A line of filter sands is available for use in municipal and industrial water treatment plants. The sands range in gradations from 0.420 millimeters to 4.76 millimeters. The company says that a 10 step process removes all clay, loam, dirt, metallic, and organic matter, leaving 99.9% pure silica. Pennsylvania Glass Sand Corp. 65

Wet scrubber
Gas sampling pump
Chemically active gases can be pumped through a new miniature Teflon pump without contamination. The Gas Sampling Pump develops pressure or suction equivalent to a 2 inch column of mercury, performs at atmospheric pressures from sea level to 2 m.b.s., and features a flow rate of 150 ml./min., accurate to & 1.556, the company says. Applications are in lab gas analysis, measurement of trace gas and air pollution, and ozone measuring devices. Science Pump Corp. 66 Phosphorus detection
Utilizing the principle of hydrogen flame emission detection, a portable instrument detects minute concentrations of phosphorus in the atmosphere. The HYFED Phosphorus Detector features an automatic alarm which operates when high levels, or predetermined levels, of concentration are reached, and may be useful in such applications as atmosphere monitoring in pesticide plants or crop spraying.

The Series 600 Mikro Venturi-Impingement Scrubber is a medium energy unit for 1+ micron size particle collection. The device features no moving parts, is available in 500-20,000 c.f.m. capacity and higher, and operates by impinging a venturi accelerated air stream on the surface of a body of water at high enough speed to shatter surface film, create turbulence, and thoroughly wet entrained dust particles.

’
The Auto-Dox is a fully automated system which controls and maintains dissolved oxygen in waste water aera- ’ I tion basins to a predetermined amount, ! according to the manufacturer. The system varies waste water level in the ! aeration basin or tank, changing the I submergence of the aerator’s blades. A sensor submerged in the tank transmits readings to an oxygen analyzer. When ! these readings fall below or exceed the prescribed oxygen content, a power unit raises or lowers the tank’s weir.

Chromium plating fumes
A new liquid additive eliminates fumes from hard chromium plating baths without causing pitting, and also is effective in decorative chromium plating operations. according to the manufacturer. Poured directly into the bath, Fumetrol 101 Fume and Spray Suppressant will not affect catalyst ratio. has no effect on balance or control of plating bath, will not lower surface tension. and remains effective for 24 hours. M&T Chemicals, Inc. 68
Batch controller
A new batch controller for oval gear flowmeters provides accurate control of batch processes, according to the manufacturer. The Brooks Model 4805 All-Pneumatic Batch Controller features preset counter, positive displacement flow meter, and pneumatic interlock system. Brooks Instrument Div., Emerson Electric Co. 71
The YSI Model 5 1 A meets the needs of the everyday user. Write for full specifications. Incidentally, the one thing we didn’t change is the price, it’s still only $260, or $375 for the complete system.
