A Computer Model To Determine Location Of Stormwater Management Practices, Alan D. Zahm
A Computer Model To Determine Location Of Stormwater Management Practices, Alan D. Zahm
Retrospective Theses and Dissertations
To optimize the placement of stormwater management systems, a Radio Shack BASIC computer program "SELECT" was written. The program selects locations for berms, detention ponds, retention ponds, and underground percolation tanks based upon minimum marginal cost (totally present value cost per pound of nutrient removed annually). Either nitrogen or phosphorus can be chosen as the selected nutrient. The selections occur until the desired percentage removal is obtained. Five output tables show the results of the selection process. The computer model was used to evaluate stormwater management locations for the Lake Tohopekaliga watershed in Florida. Input data consisting of soil types, …
Filtration Of Detained Stormwater Through Sand And Alum Sludge For Water Quality Control, Claude L. Cassagnol
Filtration Of Detained Stormwater Through Sand And Alum Sludge For Water Quality Control, Claude L. Cassagnol
Retrospective Theses and Dissertations
Stormwater detention systems as they are frequently designed do not provide good water quality control of stormwater runoff. A filtration media to be used in conjunction with detention ponds to improve their pollutant removal efficiencies was tested at the University of Central Florida and found to be effective. The filtration media, which consisted of a mixture of sand and alum sludge, substantially improved effluent water quality. Average reductions of over 80 % were observed in concentrations of dissolved orthophosphorus, total orthophosphorus and total phosphorus. Reductions were also experienced in iron, aluminum, copper and zinc concentrations. A prototype filtration model is …
Plating Wastewater Management, Earl Kenneth Ossorio
Plating Wastewater Management, Earl Kenneth Ossorio
Retrospective Theses and Dissertations
A study was made of existing methods of management, treatment and disposal of water and wastewater effluents at a large aerospace facility (Martin Marietta Aerospace) in Central Florida. Water consumption and handling were evaluated, with emphasis being placed on the handling of plating wastes, since they are the main contributor of industrial wastewater pollutants at the facility. The flow, storage, and treatment of the plating wastes were studied. Literature concerning plating wastes was surveyed to determine the latest "state of the art" on handling of plating pollutants. Then, the "state of the art" processes were compared with the existing processes …
Stormwater Management For Urban Areas, Gerald L. Chancellor
Stormwater Management For Urban Areas, Gerald L. Chancellor
Retrospective Theses and Dissertations
Stormwater management in urban areas is a major concern today. The problem of disposing of this stormwater runoff in a satisfactory manner is very difficult indeed. Both the quantity and quality aspects of the runoff must be dealt with to obtain a solution of this problem. The water quality of the runoff can vary depending upon the different land uses of the drainage basin. The quantity of the stormwater runoff also depends upon the land uses, the rainfall intensity and duration of the storm. The traditional methods available for determining the quantity of the stormwater runoff are numerous. These traditional …
Electromagnetic Fields In Water Treatment, Robert H. Fagan
Electromagnetic Fields In Water Treatment, Robert H. Fagan
Retrospective Theses and Dissertations
Properties and characteristics of colloidal systems are reviewed with a discussion of colloid systems to be found in natural and wastewaters. Current electric and magnetic field theory are reviewed and summarized to provide practical application of the theory to engineering problems in the environmental field. Literature of colloidal reactions to electrical and magnetic fields is discussed and reviewed to ascertain areas of potential application of electric and magnetic phenomena to natural and wastewater treatment systems having objectionable colloid suspensions. It is concluded that application of electrical fields (electrophoresis) does not currently hold much promise for practical applications in water treatment …
Design Considerations For Extended Aeration-Denitrification Facilities, Frank Paul Huttner
Design Considerations For Extended Aeration-Denitrification Facilities, Frank Paul Huttner
Retrospective Theses and Dissertations
Design considerations and operating procedures were investigated for nitrogen removal in an extended aeration-denitrification facility. Both past and present removal efficiencies were evaluated for the facility, along with capital and operating cost data. The findings of this research indicate that at very long detention times, significant nitrification and denitrification occurred in the plant without the use of chemicals. Overall nitrogen, BOD5, and suspended solids removals were extremely high. The significance of this research is that future plants may achieve high rates of nitrogen removal through innovative design and operating procedures without the use of costly chemicals. However, capital costs needed …
Analyses Of The Water And Wastewater Systems At Florida Technological University, Fred C. Jensen
Analyses Of The Water And Wastewater Systems At Florida Technological University, Fred C. Jensen
Retrospective Theses and Dissertations
In searching for a subject to meet the M. S. Degree Research Report requirements, I had several objectives in mind. I wanted (1) a project with relevancy in the environmental field which would broaden my understanding of the environmental systems which I have studied, (2) a subject which would allow me to apply some of the Principles which I have learned in Operations Research , and (3) a project which had good practical application. With these objectives in mind, I reviewed the suggested topics presented by the Faculty and selected the FTU Water and Wastewater System Analyses topic which was …
