The State-Of-The-Art Of The Coagulation/ Flocculation Process, David William Bouck

Retrospective Theses and Dissertations

This report has been prepared with the idea of briefly summarizing the most important principles underlying the coagulations/flocculation process as it applies to water and wastewater treatment. The production of potable water from a supply which has been contaminated by naturally-occurring or man-made pollutants has been an object of concern throughout history. Several broad aspects have been considered in the report, such as the history, the nature and physical chemistry of colloidal particles, the theories of and the factors affecting coagulation/flocculation, and control of the coagulation/flocculation process. It is advisable for those persons engaged in the dynamic environmental sciences to …

Removal Of Color From Surface Water In Central Florida, Joseph R. Wanielista

Retrospective Theses and Dissertations

The USPHS limits color in water to 15 color units. However, it is desirable to remove all the color. Color in surface water is mainly due to humic substances and was found in concentrations varying up to 450 color units. Removal of color by coagulation and flocculation has been practiced over the years. The mechanisms involved have not yet been fully understood. During the course of this investigation, a literature survey, studying the nature of color, mechanisms or color removal, and optimum color removal conditions, has been conducted. Samples have been obtained from surface waters in Central Florida; namely Big …

Kinetics And Dynamics Of Continuous Crystallization, Karichangal C. Parthasarathy

Chemical and Biological Engineering ETDs

A design correlation is presented for the prediction of steady state product size distributions resulting from a continuous crystal­lizer, based upon a single experimental determination. This has been accomplished by the definition of a new parameter called the "degree of crystallization," which has been related to the experimental nuclea­tion and growth rates in a salting-out crystallizer. The correlation resulted from the detection of variations in the suspension density of the mother liquor which has previously been assumed constant in cer­tain power law models. The degree of crystallization has also been described in terms of dimensionless number, length and area moments …

The Fate Of Hazardous Polluting Substances In An Aqueous Environment, Robert Paul Casani

Theses

The fate of Hazardous Polluting. Substances (HPS) in an aqueous environment has been investigated using ultraviolet light. Chlorobenzene, o-cresol and nitrobenzene were used as model HPS for this study. The kinetics were followed and good first order plots were obtained for all compounds. The temperature of the reaction was shown to effect the rate. Solid insoluble and soluble non-volatile products were formed in the photolytic reaction of the three model systems.

Continuous Crystallization Of High Explosives, Larry E. Hatler

Chemical and Biological Engineering ETDs

Nitroguanidine (NQ) is a high explosive which is commercially available in low bulk density form (0.20 to 0.30 gms/cm³). This low bulk density limits its usefulness as an explosive. High bulk density NQ can be produced from a NQ-N, N-dime-thylformamide-Versamid 125 system when crystallized in a mixed suspension mixed product removal crystallizer. Bulk densities ranged from 0.92 to 1.05 gms/cm³ for the operating conditions used. The effect of agitator speed, growth rate, and solids concentration on nucleation rates was determined using a multiple linear regression technique. The resulting equation is: B₀ = 0.19 (RPM) ^1.54 (G) …

Dispersion In Laminiar Flow Of Non-Newtonian Fluids, Subhash N. Shah

Chemical and Biological Engineering ETDs

In the present investigation, Taylor's analysis of the dispersion of solutes in laminar flow of a Newtonian fluid through a circular tube was extended to the case of a non-Newtonian Eyring model fluid. A new approach was taken to solve the convective diffusion equation for the Eyring model fluid. This approach incorporates the use of the dimensionless longitudinal pressure gradient and the mean velocity to obtain the dimensionless concentration. Using an approach similar to that of Taylor, a solution of the diffusion equation was obtained for quantities such as the dimensionless concentration, mean concentration, and effective dispersion coefficient as a …

Analysis Of Decomposition Gases And Leach Water From Controlled Sanitary Landfill, Robert Gargano

Theses

A sanitary landfill was simulated by placing "refuse" between two layers of soil in 6" by 24" cylinders. Canine nutriment was used to simulate the refuse. Once the refuse began to decompose, the decomposition gases were collected in a gas cell and analyzed in an Infrared Spectrophotometer. When gas samples were not taken, the decomposition gases were vented through a water trap (to prevent air from backing up into the system) into the atmosphere. Distilled water was added and withdrawn at two week intervals to leach out the pollutants.

From the Infrared analysis, the decomposition gases were determined to be …

Effectiveness Of Training Programs For Graduate Engineers, V.C. Rajashekar

Theses

This thesis represents an investigation of effectiveness as a result of engineering training. The basic elements of effectiveness and its learning process are explained and said that the effectiveness could be learnt and improved.

The term training, is basically the process of education and training. But training cannot be performed as an individual, but is performed as a group. Therefore training a group with having so many individuals needs careful consideration in designing a training program.

In order to get the broadest possible picture of current thinking and current activity in the area of company training programs for graduate engineers, …

The Reaction Of P-Nitrophenyl Acetate With Lysine Hydrochloride And Poly-1-Lysine Hydrobromide, Emmanuel Plange Matteer

Theses

The reactions of p-nitrophenylacetate with L-lysine hydrochloride and poly-L-lysine hydrobromide as a function of pH were investigated.

The results indicate that both compounds react with the substrate in the pH range 7.0-10.0 with an apparent optimum pH in the region near 9.65.

Poly-L-lysine reacts more rapidly over the entire pH range investigated than does L-lysine.

Noise Pollution And Abatement: A Review Of Literature, Kenneth R. Agent, Robert C. Deen

Kentucky Transportation Center Research Report

Complaints concerning traffic noise and possibly seismic vibrations emanating from highways would probably have been adjudicated on the basis of common law doctrines pertaining to "nuisances", "common enemy'', and ''power of relief" were it not for recent legislation and regulations directed toward protection of the total environment. In effect, "freedom from noise" has been added to the clean water, clean air, clean earth policies. Surely each of those policies are founded on public sentiment.

There have been a few instances where the Department has yielded relief because of traffic noise. Now safeguarding regulations seem inevitable.

In the past, this Division …

A Mathematical Model For Determining The Thermal Distribution Resulting From Discharge Of A Heated Effluent, Alan H. Epstein

Retrospective Theses and Dissertations

A mathematical model is presented for the problem of determining the two-dimensional temperature distribution resulting from the discharge of a heated effluent into a shallow, quiescent receptacle. The physical model of the problem is the two-dimensional jet augmented by an imposed condition of viscous drag due to bottom friction effects. By virtue of the assumption that the physical properties of the effluent are independent of temperature over the operational temperature range of the plume, the analysis separates the total problem into a flow problem and a temperature problem. Solution of the temperature distribution is accomplished both analytically and numerically. Analytically, …

The Hydraulics Of Waste Stabilization Ponds, Gary Z. Watters

Reports

The treatment efficiency of waste stabilization ponds depends primarily on the biological factors of type of waste and organic loading. However, the biological activity in a pond is greatly influenced by the environmental conditions of temperature, wind, sunlight, and the hydraulic flow patterns. In the past little attention has been given to the hydraulic characteristics of waste stabilization ponds such as the gross flow patterns within stabilization ponds as affected by the shape of the pond or lagoon, the presence of dead spaces, and positioning of inlets and outlets and the degree of density stratification. These hydraulic flow characteristics will …

Development Of Regional Supply Functions And A Least-Cost Model For Allocating Water Resources In Utah: A Parametric Linear Programming Approach, Alton B. King, Jay C. Andersen, Calvin G. Clyde, Daniel H. Hoggan

Reports

The development and allocation of the water resourcse within a state require water planners to prepare plans far in advance of the actual time new facilities are required. It is not easy to identify and evaluate all the possible alternatives for providing water which incorporate broad objectives such as economic efficiency, social welfare, regional development, recreation benefits, and conservation of environment. Water resources development entails the modification of a natural hydrologic system to better meet man's needs. The interrelationships among elements of the hydrologic system to better meet man's needs. The interrelationships among elements of the hydrologic system are relatively …

Flood Control Modeling, Peter E. Delle Donne

Retrospective Theses and Dissertations

This is a research report that discusses some continuous and discrete modeling techniques. The report applies these techniques to the analysis of Canal 38 (Kissimmee River) part of Central and South Florida Flood Control District. The analysis is based on recorded data for defining the physical systems parameters. Established parameters are mathematically related to define a descriptive model for Canal 38. The modeling procedure of 'trial and error' is used to assemble the model with measures of merit, the integral square error, and root mean squared error. General simulation considerations are discussed for application of the mathematical model.
