Black carbon (BC) is a significant component of fine particulate matter (PM2.5) air pollution, which has been linked to a series of adverse health effects, in particular premature mortality. Recent scientific research indicates that BC also plays an important role in climate change. Therefore, controlling black carbon emissions provides an opportunity for a double dividend. This study quantifies the national burden of mortality and morbidity attributable to exposure to ambient BC in the United States (US). We use GEOS–Chem, a global 3-D model of atmospheric composition to estimate the 2010 annual average BC levels at 0.5 x 0.667° resolution, and …

Driver Dynamics And The Longitudinal Control Model, Gabriel Leiner
Driver Dynamics And The Longitudinal Control Model, Gabriel Leiner
Gabriel Leiner
Driver psychology is one of the most difficult phenomena to model in the realm of traffic flow theory because mathematics often cannot capture the human factors involved with driving a car. Over the past several decades, many models have attempted to model driver aggressiveness with varied results. The recently proposed Longitudinal Control Model (LCM) makes such an attempt, and this paper offers evidence of the LCM's usefulness in modeling road dynamics by analyzing deceleration rates that are commonly associated with various levels of aggression displayed by drivers. The paper is roughly divided into three sections, one outlining the LCM's ability …

Wastewater Treatment And Management At Oil Shale Plants, R. E. Hicks, R. F. Probstein, I. Wei, D. S. Farrier, J. Lotwala, T. E. Phillips
Irvine W. Wei
Laboratory tests have shown that the major wastewater streams produced during oil shale retorting can in principle be treated to a quality suitable for reuse within the plant. The wastewater stream condensed from the retort gases, here called the gas condensate, contains primarily dissolved gases (NH3, CO2 and some H2S) and organics as contaminants. In batch stripping tests it was found that the organics, which may be present at concentrations of up to 5,000 mg/l measured as COD, are volatile and can be stripped along with the ammonia down to about 500 mg/l COD. Retort waters, or wastewater streams that …

Advanced Chemical Oxidation And Toxicity Reduction Of 2,4,6-Trichlorophenol By Using Fenton's Reagent: Part Ii, Dechlorination Kinetics, Somnath Basu, Venkat Sreenivasan, Irvine W. Wei
Irvine W. Wei
Laboratory investigation has shown that Fenton's Reagent is a very effective oxidant for 2,4,6-Trichlorophenol (TCP). The authors reported the first phase of this research, consisting of five different reactions of Fenton's Reagent on TCP, at the 1995 AIChE Summer National Meeting in Boston as Part I of this paper. The results demonstrated total removal of TCP, with almost complete release of aromatic ring bound chlorine atoms into chloride ions, significant reduction of TOC, and very importantly, significant toxicity reduction compared to the original substrate. These results suggested that Fenton's Reaction can be considered as a candidate process for treatment of …

Uv Disinfection Of Treated Wastewater Effluent: Influence Of Color, Reactivation And Regrowth Of Coliform Bacteria, Somnath Basu, Jack Page, Irvine Wei
Irvine W. Wei
Disinfection is a very important unit process to deactivate coliform bacteria in treated wastewater. However, regrowth potential of coliform bacteria raises human health and safety concerns associated with reuse of treated wastewater in various applications. Both post chlorination and post UV disinfection regrowth have been reported in the literature. In view of increasing use of recycled wastewater for reuse, it is necessary to address this phenomenon from both technical and regulatory standpoints. A case study of fecal coliform regrowth in a full scale operating plant is reported here. This is expected to aid in further understanding of the phenomenon and …

A Conceptual Continuous Process For The Treatment And Toxicity Reduction Of Wastewater Contaminated With 2,4,6-Trichlorophenol: Extended Abstract, Somnath Basu, Irvine W. Wei
Irvine W. Wei
Fenton's Reagent is an aqueous solution of ferrous ions and hydrogen peroxide. Through laboratory experiments Fenton's Reagent has been shown to be an excellent treatment agent for the removal of organic contaminants dissolved in water. It carries out oxidative degradation of various organic substrates using the principle of advanced chemical oxidation. This is an excellent alternate route for the removal of hazardous and toxic chemicals, which are recalcitrant to biological treatment. The authors of this paper conducted an extensive laboratory investigation to study the degradation of 2,4,6- Trichlorophenol (TCP) using Fenton's Reagent, reported elsewhere. The results indicated an optimum H₂O₂:TCP …

Irvine W. Wei
The objective of this study is to exmnine the removal of a priority chlorinated aromatic pollutant, 2,4,6-Trichlorophenol (TCP), in aqueous solution by using Fenton's Reagent (a mixture of hydrogen peroxide and ferrous iron catalyst). Chlorinated phenols are priority pollutants, regulated by stringent discharge litnits. The presence of chlorine increases the toxicity of these phenolic compounds and decreases their biodegradability. Therefore, the processes of oxidation and dechlorination of chlorinated phenols by using Fenton's Reagent were employed in this study. Experiments were conducted in one-liter stirred batch reactors at 20°C. Three parallel reactors were used for reactions between 0.25 mM 2,4,6-TCP and …

Water Management In Oil Shale Production, R. Edwin Hicks, Ronald F. Probstein, Irvine Wei
Irvine W. Wei
Material balance calculations for several proposed oil shale processes have been made and show that water requirements vary from 2 to 5 times the product oil rate. Wastewater is produced at from one-third to 1.5 times the product oil rate and may be treated and used to offset the source water requirement. Water management schemes are used to show the degree of treatment required for each type of wastewater. Conceptual designs of treatment trains, based on laboratory investigations of reverse osmosis, resin adsorption, biological oxidation and steam stripping processes on actual wastewaters, show that water management costs range from 60¢ …
