THE DESTRUCTION OF ORGANIC HAZARDOUS WASTE BY ELECTRIC ARC PYROLYSIS HAS BEEN DEMONSTRATED TO BE TECHNICALLY FEASIBLE BY OTHERS. THE PRINCIPAL PROBLEMS LIE IN (1) THE SHORT LIFEOF THE ELECTRODES (AND RELATED STRUCTURES) DUE TO THE HIGH TEMPERATURES INVOLVED, AND (2) THE RELATIVELY HIGH COST OF THE ELECTRIC POWER NEEDED. APPLIED RESEARCH ASSOCIATES, INC. PROPOSE TO DESTROY ORGANIC HAZARDOUS WASTE B ...

Accelerated development of directed energy technologies has presented new problems to mission planners and weapon operators regarding the capabilities, lethality and performance of weapon systems. The Emerging Weapons Technology Evaluation Model willaddress these shortcomings by providing users of varying technical expertise 1) the ability to model a variety of weapons in various mission scenario ...

THE PLATING AND ELECTRONICS INDUSTRIES ARE REQUIRED BY STATEAND FEDERAL REGULATIONS TO REMOVE TOXIC, HEAVY METALS FROM WASTEWATER STREAMS BEFORE DISCHARGE. THE SEMICONDUCTOR AND AND PRINTED CIRCUIT INDUSTRY ALONE REMOVED OVER 7.2 TONS OF HEAVY METALS FROM WASTEWATER IN 1983. MUCH OF THE RECOVERED METALS ARE DISCARDED AS SLUDGES, BECAUSE TECHNIQUES FOR RECOVERING AND SEPARATING THE METAL IONS ARE U ...

One of the program areas of interest to the U.S. Environmental Protection Agency (EPA) is the development of rapid, non-invasive monitors to detect exposure to toxic air pollutants at trace (ppt) levels. Of the 356 chemicals listed on the Chemical Emergency Preparedness and Prevention Office¿s List of Extremely Hazardous Substances (Section 302 of the Emergency Planning and Community Right-To-Kn ...

Subsurface treatment for arsenic removal (STAR) is an innovative technology for treatment of arsenic in groundwater at the wellhead. The STAR technology can result in large cost savings when compared with conventional above-ground treatment methods. The goal is to create a subsurface biogeochemical barrier composed of reactive iron hydroxide minerals and iron bacteria within the aquifer surround ...

STATIONARY GAS ENGINES PRODUCE A DISPROPORTIONATELY LARGE SHARE OF THE TOTAL NOX EMISSIONS IN THE U.S., BUT NO AVAILABLE TECHNOLOGY OFFERS A SATISFACTORY MEANS OF REDUCING THEIR EMISSIONS. THESE ENGINES ARE PREDOMINANTLY TWO CYCLE AND PRODUCE AN EXHAUST HAVING A HIGH RATIO OF OXYGEN (O2) TO NITRIC OXIDE (NO). THUS, A SELECTIVE NO REDUCTION TECHNIQUE IS NEEDED WHICH CONVERTS THE NO TO NITROGEN (N2) ...

DURING HAZARDOUS WASTE INCINERATION A PHENOMENON KNOW AS PUFFING OCCURS, I.E., A LARGE AMOUNT OF ORGANIC MATTER SUDDNELY VAPORIZES IN THE COMBUSTION CHAMBER. SINCE THE SUPPLY OF COMBUSTION AIR IS NOT ADEQUATE FOR COMPLETE OXIDATION OF THIS SUDDENLY RELEASED ORGANIC MATTER, IT CANNOT BE COMPLETELY OXIDIZED, AND ESCAPES FROM THE INCINERATION IN A PUFF. THE FACT THAT COMMERCIAL HAZARDOUS WASTE INCINE ...

To help improve air quality, the U.S. Environmental Protection Agency is seeking innovative and cost-effective new technologies to remove volatile organic compounds (VOCs) from the emissions of stationary sources. The current technologies, carbon adsorbers and catalytic thermal oxidizers, are heavy, expensive, insufficiently regenerating, and sometimes not sufficiently effective to meet regulator ...

The overall goal of this program is to build a compact, lightweight, portable laboratory kit that can be used to analyze chemistries, cell counts, parasites, bacteria, and other pathogens in blood, urine, and body fluids. Our proposed Portable Micro-Lab(PML) kit will be composed of two sub-systems:1) Environmentally stable microdot test strips smaller than a stick of chewing gum and containing th ...
