As the number of mobile source emissions in the United States increases, it is necessary to further reduce the emission of CO, NOx, and hydrocarbons from such sources to provide safe air quality, especially in urban environments. Significant reductions in pollution emissions can be achieved using advanced engine controls based on real-time measurements of CO, NOx, and hydrocarbon concentrations i ...

THIS RESEARCH INVESTIGATES THE FEASIBILITY OF DEVELOPING AN INNOVATIVE OPTRODE DEVICE FOR THE DETECTION, IDENTIFICATION, AND QUANTIFICATION OF TRACE LEVELS OF CHEMICAL CONTAMINANTS IN WATER. THIS FIBER OPTIC BASED INSTRUMENT WILL HAVE A RESPONSE DETECTOR AND CAN MEASURE CONCENTRATIONS OF CONTAMINANTS AT PARTS PER BILLION CONCENTRATIONS. IT IS ALSO ANTICIPATED THAT THIS INSTRUMENT WILL BE ABLE TO I ...

A number of very high-volume liquid chemicals form azeotropes with water and can be dehydrated to required purity levels only through the use of entrainers or drying agents. The handling and disposal of these additional chemicals present significant environmental risks. Recently, membrane pervaporation using both polymeric and inorganic membrane modules has been commercialized as a method to deh ...

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 ...

Combined sewage outflows (CSOs) are a major contributor to water pollution in the United States. The impact of peak stormwater loads on sewage treatment plants leads to the discharge of significant amounts (1.26 billion gallons) of untreated sewage each year. The bacterial load represented by this discharge directly contributed to more than 2,200 beach closings in the year 2000, numerous closing ...

Copper compounds have been used for centuries in marine antifoulants to inhibit biofouling. This anthropogenic copper is a potential problem in confined basins and in regions that experience limited mixing. In this research project, E Paint Company will explore the feasibility of developing novel self-polishing coatings that exploit natural methods of biofouling control to produce effective and ...

There has been an alarming increase in toxic cyanobacteria during the past 2 decades, with numerous poisonings reported from Australia to the United States. The increased toxic risks led the U.S. Environmental Protection Agency (EPA) to include cyanotoxins on the 1998 Contaminant Candidate List. However, most cyanobacterial blooms are not toxic. Further, bloom toxicity will change over time. T ...

SAFE, COST EFFECTIVE ALTERNATIVES TO CHLORINE TREATMENT OF DRINKING WATER FOR DISTRIBUTION AND DISINFECTION HAVE BEEN SOUGHT FOR SOME TIME. CHLORINE DIOXIDE IS A VIABLE ALTERNATIVE TO CHLORINE FOR THE TREATMENT OF EVEN POOR QUALITY WATER SUPPLIES AND THE REDUCTION OF POTENTIAL CANCER CAUSING CHLORINATED ORGANICS. ITS WIDESPREAD USE HAS BEEN INHIBITED BY THE COSTS AND/OR COMPLEXITY OF ITS PRODUCTIO ...

THERE ARE NUMEROUS INDUSTRIAL PROCESSES REQUIRING THAT MATERIAL BE HEATED AND THEN SUBSEQUENTLY COOLED. IF MOST OF THIS HEAT IS RECOVERED AND RECYCLED TO THE OVEN, THE NET POWER INPUT TO THE OVEN COULD BE SUBSTANTIALLY REDUCED. THE KEY TO ACCOMPLISHING THIS IS AN INCREASE OF THE HEAT TRANSFER COEFFICIENT BETWEEN GAS AND MATERIAL SO THAT THE HEAT EXCHANGERS ARE RESASONABLY COMPACT. SIMPLE EXPERIMEN ...

Engineering Mechanics Corporation of Columbus¿ (Emc2) approach is to convert both municipal and industrial solid waste products into large dimensional composite timbers for structural and waterfront applications through a novel and efficient manufacturing process. The environmental benefits include: (1) diversion of solid waste plastics and reinforcements from landfills; (2) pollution prevention ...
