Hydrogeologic Investigation of the Chillicothe, Ohio Landfill
A hydrogeologic investigation of a municipal waste landfill determined that the local surface and ground water are being polluted. Water quality monitoring and aerial photography were...
Comparison of Two Audits for Electric Utilities
Two case studies on environmental audits were examined to illustrate the differences between the comprehensive audit and a focused audit. The differences in audit team composition, technical...
Full-Scale Automation of an SBR Wastewater Treatment Facility
Due to advantages offered by discontinuous wastewater processing, considerable attention has been given to the use of sequencing batch reactor (SBR). This paper will examine the implementation...
Incinerating Dioxin Contaminated Waste at the USEPA Combustion Research Facility
The objective of the tests reported herein was to evaluate the incinerability of the toluene stillbottoms by determining whether 99. 9999% DRE could be achieved. All tests were performed...
Power from the Incineration of Wastewater Sludge
The City of Kansas City, Kansas recently completed an upgrading of their existing primary treatment and sludge handling system in preparation for the addition of a high purity oxygen activated...
Trace Toxic Metals Emissions from Hazardous Waste Incinerators
A physical model is proposed in order to explain the vaporization of metals during metallic waste incineration and is based on work performed to investigate inorganic emissions from coal...
Multiple-Hearth and Fluid Bed Sludge Incinerators
This paper presents recommended practices for design and operation of multiple-hearth and fluid bed furnace systems for combustion of sludges in order to eliminate or mitigate the problems...
Detoxifying Metal-Contaminated Solid Wastes by Induced Ion Exchange?A Theoretical Evaluation
The presence of minor amounts of insoluble heavy metal precipitates may render a large body of innocuous solids (say fly ash, soil, calcium carbonate or even biological sludge) potentially...
Application of a Relative Site Ranking Methodology to Regulation of Groundwater Contamination Sites
An assessment methodology for ranking groundwater contamination sites is described. The ranking of nearly 100 actual contamination sites, and the definition and calibration of 'zones...
Biological Removal of Low Levels of Chlordane
This study investigated the removal of chlordane from a synthetic hazardous waste landfill leachate with chlordane as the only hazardous material. The chlordane concentrations investigated...
Effects of Organic Compounds on the Adsorption and Desorption of Metals in Soils
This study evaluated the adsorption and release rates of toxic metals in a soil system also impacted with organic compounds. The soil type studied is common to hazardous waste sites throughout...
Development of a Rule Based Expert System for Characterization of Hazardous Waste Sites
The area of hazardous waste management is a broad and multidisciplinary field requiring expertise in engineering, geology, chemistry and toxicology, and is an ideal area for the application...
Effect of Wastewater Characteristics on the Sulfide Problem (
This paper presents an overview of various wastewater characteristics with which the designer should be familiar, and the effect of those characteristics on the sulfide problem, including...
Land Disposal Construction, Monitoring and Closure
The continuous generation of hundreds of thousands of gallons of hazardous wastewater and waste process solutions each year at an aerospace development and assembly plant at Lockheed Missiles...
Initial Operations Report
In the fall of 1983, Fort Collins City placed into operation its 152. 6 hectare (377 acre) Resource Recovery Farm, which receives liquid sludges from the City's wastewater...
Reduction of Nitrogen and COD by Land Disposal of Dairy Wastewater
Land disposal of industrial wastewater, and in particular the ridge and furrow (R&F) process, has been a popular and simple treatment method for many years. This study, conducted...
Design Study of an Above-Grade Landfill
A design study on the feasibility of utilizing an above-grade landfill for the disposal of hazardous wastes has been completed. This design study comprised three phases of work - a literature...
Lessons Learned Implementing the Minimum Technology Guidance for Landfills
The 'Minimum Technology Guidance on Double Liner Systems for Landfills and Surface Impoundments' issued by the Environmental Protection Agency (EPA) in May 1985...
Clay Liner Hydraulic Conductivity: Comparison of Field & Laboratory Tests
Clay liner hydraulic conductivities at three hazardous waste landfill cells in Oklahoma and Utah were measured in the laboratory and in the field during construction. Prior to construction...
Mixing and Polymer Performance in Sludge Dewatering
A biofilm reactor, termed the support-aerated biofilm (SAB), was developed in which oxygen was supplied to the interior of the biofilm through a permeable membrane. The reactor was tested...
