Remedial Measures for a Creosote Impoundment Closure
In conformance with the 1984 amendments to the Resource Conservation and Recovery Act (RCRA) Part 264 requirements, Burlington Northern Railroad (BN) constructed a double high density...

Effect of Wastewater Characteristics on the Sulfide Problem (abstract)
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...

Computer Modeling of Collection Systems for Sulfide Evaluation (abstract)
An overview of two computer models and a nomograph model for sulfide prediction is presented. The first program, 'SULF. BAS', is a Basic Language computer model...

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...

Risk Assessment Methodology for Determining Groundwater Contamination from Landfilling Sludge
Contaminant concentration criteria are required to prevent contaminant infiltration from leading to conditions which exceed health criteria. A methodology of groundwater has been described...

Clay Liner/Leachate Compatibility Modeling
Over the past several years, the results of many laboratory studies assessing the effect of various combinations of organic and inorganic chemical mixtures on the hydraulic conductivity...

Sulfide Control in Omaha and Cedar Rapids
Omaha, Nebraska, and Cedar Rapids, Iowa have been involved in efforts to control sulfide in major interceptors, at the influent to the treatment plants, and within the treatment facilities....

Safety Aspects of Sulfide and Corrosion Studies (abstract)
An overview of the hazards involved in performing sulfide and corrosion studies in sewage treatment and collection systems is presented. Important factors which should be recognized in...

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...

Leaching Characteristics of Metal Finishing Sludges
The purpose of this research was to study the feasibility of biodegrading phenolics to methane by thermophilic anaerobic treatment. The study was a feasibility level assessment which examined...

Heat Treatment and Low Pressure Oxidation Systems
A study was performed to identify problems and to document solutions in the design, operation, and maintenance of heat treatment and low pressure oxidation systems for conditioning sludge...

Assessment of Analytical Techniques for Monitoring Petroleum Waste Land Treatment Systems
Optimization of wastewater land treatment effectiveness requires current knowledge of the microbiological ecosystem. Environmental parameters must be measured if they are to be adjusted...

Treatment Facilities and Costs for the Removal of Radon from Ground Water Supplies
Two methods for removal of Radon from drinking water are considered: activated carbon adsorption and packed tower aeration. Although both granular activated carbon (GAC) and packed tower...

Removal of EDB from Groundwater by Granular Activated Carbon Filtration
Application of ethylene dibromide (EDB) pesticide to crops may result in contamination of groundwater. Various water treatment alternatives are: granulated activated carbon adsorption,...

Hydroelectric Program for Development in Mexico
This work deals with the process at present followed in Mexico for the development of hydroelectric projects. Then, the participation of hydroelectricity in the electric sector is given...

Cherokee Nation Power Development at a Corps Lock and Dam
In an arrangement among the Cherokee Nation of Oklahoma, the U. S. Army Corps of Engineers and the Southwestern Power Administration, the Cherokee tribe will finance, design and construct...

Future Hydrothermal Power of the United States
Public indignation toward nuclear-power expansion, and dwindling oil and gas reserves dictate the needs to look for alternative-power sources, such as coal and water. It is a prime time...

The Local Perspective on Agricultural Drainage
This paper discusses shallow, perched groundwater and resulting agricultural drainage and salt problems that have developed in the San Joaquin Valley of California over the past 30 years....

Incorporating Judgment into an Optimization Model of a Wastewater Treatment System
The use of design variable constraints according to textbook and state design standards might cause potentially good designs to be missed and would not capture the fuzzy interaction of...
