Nitrogen Transformation In Secondary Wastewater Treatment Plants, Mark Lee Morris

Retrospective Theses and Dissertations

Nitrogen is an essential nutrient for plant and animal life; however, its presence in concentrations exceeding assimilative capacities of receiving water bodies is undesirable. Therefore, the form and concentration of total nitrogen released in wastewater effluents is of great concern. During the course of this study, the nitrogen analysis was performed on the various unit processes of the Florida Technological University wastewater treatment plant. The average percent removal of nitrogen between plant influent and clarifier effluent was 30.5% during the month of August 1975. It is believed that the nitrogen removal is attributed to luxury uptake by the biomass through …

Design And Analysis Of An Instrument System For Rheological Testing Of Whole Blood Samples, Robert Rimvydas Sinusas

Dissertations

The dissertation covers the conceptual design of a rheometer for testing whole blood samples through to the clotting state. While the design aims at increased measurement accuracy, the design employs well known technologies and available components.

The main reason for preoccupation with blood testing is that recent investigations have indicated that physiological disorders can be correlated with rheological properties of blood. The pursuit of an improved means of correlation is initiated with a survey of the rheological properties of blood. The relevance of these blood properties is then discussed. From this discussion a broader blood model is developed as a …

Development And Preliminary Application Of Mathematical Models To The Weber Basin, W. J. Grenney, D. S. Bowles, M. D. Chambers, J. P. Riley

Reports

The adoption of stream standards, whether for direct application or for the establishment of realistic effluent standards, creates a need to predict the impact of pollution loads on river water quality during critical flow periods or as the result of future user demands. Because of the complexity of aquatic systems, mathematical models are an excellent medium for bringing together the state-of-the-art knowledge from a variety of disciplines into a form which can be readily applied to practical problems. Applying a mathematical model to a river system has the added advantage of providing a structure for the systematic consideration of the …

Water Salvage Potentials In Utah, Volume I. Open Water Evaporation And Monolayer Suppression Potential, Trevor C. Hughes, E. Arlo Richardson, James A. Franckiewicz

Reports

An estimate of the potential in Utah for evaporation suppression by the monolayer film method is presented. The model estimates evaporation suppression as a function of wind speed, a four parameter exposure factor, and reservoir size. The estimated suppression factors vary from 0 to 30 percent and average 11 percent of the statewide total annual evaporation. Estimates of May to October evaporation and suppression potential are calculated for each of the 227 impoundments in the surface water inventory. A forthcoming report in this series will examine the potential for evaporation suppression by thermal destratification. This procedure, which is already being …

The Theory Of Multiple Measurements Techniques In Distributed Parameter Systems, Babajimi Claudius Okunseinde

Dissertations

A comprehensive theory of multiple measurements for the optimum on-line state estimation and parameter identification in a class of noisy, dynamic distributed systems, is developed in this study. Often in practical monitoring and control problems, accurate measurements of a critical variable are not available in a desired form or at a desired sampling rate. Rather, noisy independent measurements of related forms of the variable may be available at different sampling rates. Multiple measurements theory thus involves the optimum weighting and combination of different types of available measurements. One of the contributions of this work is the development of a unique …

A Nonlinear Viscoelastic Model, Yon-Li Shangkuan

Dissertations

A nonlinear viscoelastic model has been developed to describe the non-Newtonian viscosities and the primary normal stress differences of high polymers at steady-state shearing flow.

It has been demonstrated that the Huang-Shangkuan model gives the best representation of the experimental data for a wide range of shear rates. In the high shear rate region the Huang-Shangkuan model is distinguished among other models by its capability to predict the nonNewtonian viscosities and the primary normal stress differences Which the other models fail to predict.

Continuum mechanics, Lodge's network theory and Rouse's theory provide specific information in developing our model. The theoretical …

Phosphorus Budget Of The Hyrum Reservoir - Little Bear River System, William A. Luce

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphorus concentrations in the water of the Hyrum Reservoir - Little Dear River Watershed were determined by collecting 12 samples every two weeks over a seven month period and analyzing them for dissolved orthophosphate, total dissolved phosphorus, and total unfiltered phosphorus.

The concentrations obtained were used in conjunction with a water budget to determine a phosphorus budget. Apparent major inputs of phosphorus to the reservoir included a trout farm and runoff from agricultural land in the watershed.

Statistical analyses of the data were made to determine what effect precipitation, streamflow, and mileage downstream had on the concentrations of phosphorus in …

An Evaluation Of In-Stream Structures Designed To Provide Fish Habitat, Charles H. Call Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In-stream concrete structures were studied through model tests and river tests. The model studies indicated that four designs provided good habitat in the model stream. These structures were the inverted weir, the "V" structure, the slab with legs and the cylinder. Through the river studies it was determined that these structures did not influence enough of the total river area to be effective in providing good fish habitat. Also an appreciable amount of yearly maintenance would be required to free the structures from silting in, debris, and vandalism. The slab with legs was the only promising structure.

Locating Nuclear Power Plants Underground, Frank M. Scott

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

This paper reviews some of the questions that have been asked by experts and others as to why nuclear power plants are not located or placed underground. While the safeguards and present designs make such installations unnecessary, there are some definite advantages that warrant the additional cost involved. First of all, such an arrangement does satisfy the psychological concern of a number of people and, in so doing, might gain the acceptance of the public so that such plants could be constructed in urban areas of load centers. The results of these studies are presented and some of the requirements …

Energy From Biochemical Sources, G. J. Fennewald, D. L. Million, Efton Park, J. L. Gaddy

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

As available energy reserves decline, renewable sources must be utilized. Organic matter, grown agriculturally, represents a renewable energy source, which is readily available. This paper reviews the methods by which organic matter can be converted to energy sources by biochemical processes. The economics of conversion of agricultural crops and byproducts to alcohols by fermentation and conversion of these agricultural materials to methane by anaerobic digestion are examined. Projections of the potential of this energy source are quite promising.

Oil Spill Containment And Removal In Arctic Ecosystems, Wilfred R. Mcleod, Diana L. Mcleod

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Statistics on 16 arctic and subarctic oil spills, their locations, the amount of oil spilled, combatant schemes used, and causes for the spills were culled from the literature. This information has been used to analyze the effectiveness of available chemical, mechanical, and destructive means of oil recovery or disposal under arctic and subarctic conditions.

The choice of the best cleanup procedures to follow in any particular instance is clouded by a number of variables and must be weighed against such considerations as wind, sea, and ice conditions, properties of the oil, and effects of chemicals on marine and wildlife. Access …

Interfaces Of Steam Electric Power Plants With Aquatic Ecosystems, Gerald J. Lauer, William T. Waller, Guy R. Lanza

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Growth and reproduction may be stimulated by increased temperature in the cooling system and thermal plume during seasons when ambient water temperature is less than optimum, but growth, reproduction and survival are reduced when the elevated temperatures become excessive. Some fish species congregate in the warm thermal plumes during cold seasons but are excluded from this living space by temperatures above their preference in the summer. However, the warm refuge provided by a thermal plume in cold seasons can be a death trap if a power plant shuts down suddenly and exposes the fish to cold shock exceeding their lower …

The Condensation Of Vapor On A Horizontal Rotating Square Tube., Suresh Chandra

Chemical and Biological Engineering ETDs

Heat transfer measurements were made for steam vapor condensing at one atmosphere on the outer surface of a horizontal square tube with a side of one inch, when rotated at between O and 1950 rpm. The Froude number (FR) was based on the side length. Three distinct heat-transfer regimes were observed and are correlated with FR. The first is gravita­tion controlled condensate flow when FR is less than 2.0 and the condensing film heat-transfer coefficient decreases. When 2.0

Review Paper: Evaluation Of Techniques For Algae Removal From Wastewater Stabilization Ponds, E. Joe Middlebrooks, Donald B. Porcella, Robert A. Gearheart, Gary R. Marshall, James H. Reynolds, William J. Grenney

Reports

Introduction: Approximately 90 percent of the wastewater lagoons in the United States are located in small communities of 5,000 people or less. These communities, many with an average daily wastewater flow of only 175,000 - 200,000 gallons, do not have the resources to keep man at the lagoon sites throughout the day (38). A high degree of technical knowhow is usually lacking in these communities. Often only periodic inspection or maintenance is carried out by the general municipal work force. Therefore, the development of a relatively inexpensive method that does not require sophisticated and constant operation or extensive maintenance is …
