This Phase I research project will develop a new, low-cost carbon monoxide sensor for small industrial burner feedback control systems that will help meet the regulatory goals of minimizing pollution and optimizing heat release for these systems. This device will permit precise control of the burner using a simple, fully solid-state optical sensor that employs microelectric mechanical systems tec ...

There is a need for new technologies to control restaurant emissions. There are more than 870,000 restaurants in the United States. Most of these restaurants have under-fired charbroilers, creating a significant amount of particulate matter (PM) and volatile organic compounds (VOCs) that have been classified as health and environmental hazards by the U.S. Environmental Protection Agency (EPA). Alt ...

In this research project, Southwest Sciences, Inc., proposes to design, build, and test a real-time, field-portable instrument for the detection of polycyclic aromatic hydrocarbons (PAHs). The technology uses time- and wavelength-resolved fluorescence spectroscopy (T&WFS) to identify PAHs at sub-parts-per-billion concentrations in water. The instrument incorporates an innovative approach to fluore ...

As stated in the EPA 2004 Solicitation topic B1, there is a need for new technologies to control restaurant emissions. There are over 870,000 restaurants in the United States. Most of these restaurants have under-fired charbroiler creating a significant amount of partifculate matter and volatile organic compouns which have been determined health and environmental hazareds by the EPA. Although s ...

SLUDGE WASTE CONTAINING CR(VI) FROM CHROMIUM PLATING OPERATIONS IS CLASSIFIED AS HAZARDOUS AND ITS DISPOSAL IS A MAJOR CONCERN. IT CAN BE RECOVERED FOR FUTURE METAL USE IN REMELTING OPERATIONS, CAN BE STORED, OR CAN BE DISPOSED AFTER MODIFICATION TO A LEGALLY ACCEPTABLE FORM. IN PHASE I, THE CONVERSION OF SLUDGE WASTE FROM CHROMIUM PLATING OPERATIONS INTO FERROCHROMIUM ALLOYS IS PROPOSED. BY MEANS ...

THE CHLORINE CONTENT OF CARBONACEOUS CHAR DERIVED FROM THE PYROLYTIC CONVERSION OF REFUSE-DERIVED FUEL (RDF) IS HIGHER THAN THAT OF CONVENTIONAL COAL. THE PROPOSED RESEARCH WILL DETERMINE IF THIS CHLORINE CAN BE "CAPTURE" DURING THE PYROLYTIC CONVERSION BY THE ADDITION OFCA(OH)2 OR NAOH, AND THE EXTENT TO WHICH IT CAN BE "CAPTUREDTHE RESEARCH WILL IDENTIFY THE RELATIONSHIP BETWEEN THE AMOUNT OF CH ...

TRICHLOROETHYLENE (TCE) IS A WIDESPREAD POLLUTANT AND IS REPORTED TO BE THE MOST FREQUENTLY ENCOUNTERED CONTAMINANT AT HAZARDOUS WASTE SITES. ALL PREVIOUS ATTEMPTS AT IN SITU BIOREMEDIATION HAVE USED A PROCESS WHERE METHANTROPHIC BACTERIA WERE STIMULATED BY THE SUBSURFACE DELIVERY OF AIR AND METHANE RESULTING IN A "FORTUITOUS" COMETABOLISM OF TCE. THIS PROCESS AT ONE TIME APPEARED PROMISING FOR TH ...
