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 (
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...
Small Hydro is Very Rarely Typical
Engineering design of a small hydro project is often considered to be straightforward. Many potential developers assume that the engineering effort can be reduced to 'typical'...
Diamond Fork Hydroelectric Power Development
The Strawberry Valley Project was conceived in the early 1890s as an irrigation project to supply a maximum of 635 cfs of water from the Strawberry Reservoir through a 3. 8-mile-long tunnel...
Hydropower on the Arkansas?A Non-Federal Development
Only two of the eleven navigation locks and dams in Arkansas were initially constructed with hydropower facilities. In 1980, Arkansas Electric Cooperative Corporation (AECC) filed preliminary...
Water Management of the Snowy Mountains Scheme Australia
The Snowy Mountains Scheme in south-eastern Australia provides a classic example of Water Resources Planning and Management on a National scale. The Scheme provides mainly peak electricity...
