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...
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...
Hydrodynamics of Earth Fill Dam Breach Erosion
An analytical model is suggested in this paper. The model is based on the continuity equation of water mass within the reservoir, a broad-crested weir discharge formula and a velocity...
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...
Remote Sensing to Assess Effects of Hydroelectric Development
Planning for hydroelectric development of rivers in the province of Ontario, Canada requires extensive environmental evaluation and assessment. To test the feasibility of using digital...
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...
The Rx for Relief from Equipment Failure
A predictive maintenance program was developed for a treatment plant with a large number of pieces of critical mechanical equipment. Using an inexpensive, portable vibration meter, data...
Investigating and Treating Chromium in Ground Water at a Wood Treater in California
A wood treating facility, operating for more than five years without required permits, contaminated soil and ground water on and offsite. The company moved slowly in response to enforcement...
Applied Hydro System Operations Models
The paper discusses computer simulation of system operations. Computer programs that simulate operations through future time periods on hourly, daily or monthly time periods are routinely...
California Water Project Operation
The California State Water Project (SWP) is operated and managed using state-of-the-art operations research and optimization techniques. Medium- and long-range studies for the operation...
Model to Maximize Releases for Supplemental Generation in a Pump-Storage System
An optimization model has been developed to maximize releases for supplemental power generation in a pump-storage system. The model was developed to aid in the scheduling of pump-storage...
Evolving Institutions for Water Transfer in the U.S.
A major source of constraint is state water allocation law, which defines rights for water use and development, including in some cases restrictions on place of use that limit transfer....
Evaluation of Tertiary Wastewater Treatment Systems
The purpose of this paper is to evaluate factors affecting the optimum operations of coagulation-flocculation and filtration processes in municipal wastewater reclamation and reuse. Special...
Reusing Treated Wastewater for Irrigation of Raw-Eaten Vegetable Crops in Monterey County, California
The demonstration project was entitled the Monterey Wastewater Reclamation Study for Agriculture (MWRSA). It was principally a field trial study of the feasibility of irrigating food crops...
