Show moreThis thesis presents a model which estimates energy and cost savings that can be realized by implementing Energy Conservation Measures (ECMs) at mechanically aerated wastewater treatment plants (WWTPs) in southeast Florida. Historical plant monitoring data is used to estimate savings achieved by implementing innovative aeration technologies which include : 1) Fine Bubble DIffusers ; 2) Single-Stage Turbo Blowers ; 3) Automatic Dissolved Oxygen (DO) Control. Key assumptions for modeling performance of each technology are researched and discussed, such as trends in the future cost of electricity, efficiency of blowers, and practical average DO levels for each scenario. Capital cost estimates and operation maintenance (O&M) costs are estimated to complete life-cycle cost and payback analyses. The benefits are quantified on an individual and cumulative basis, to identify which technologies are cost-beneficial. The results demonstrate that levels of payback of 20 years or less are available at the three WWTPs studied.

Show moreA comparative risk assessment of wastewater disposal methods in southeast Florida has only been performed once and it was over 20 years ago. Since then, methods has changed and research have been developed. This study follows the methods used in the 2000 study, and assesses the following disposal methods: ocean outfalls, deep injection wells, surface water discharge, reuse for non-potable applications, indirect potable reuse, and direct potable reuse. This assessment assembled a team of qualified experts to complete a modified delphi survey to assess the human risks of wastewater disposal methods. Using the delphi results in a Bayesian Assessment Model, this assessment found that deep injection well and direct potable reuse were the disposal methods with the least risk.

Title: A Study of the Longevity of f2 Bacteriophage in Marine and Fresh Water Sewage Effluent, and Its Use as a Biological Indicator of Pollution.
Creator: Twist, Ernest Michael, Waddell, Glenn H., Florida Atlantic University
Abstract/Description: The significance of the transmission of animal viruses in sewage polluted fresh and marine waters becomes an increasingly important factor as more and more evidence is presented to support the fact that in the case of many viral types one virus particle constitutes an infective dose. Therefore it is very important that a method of determining the extent of viral pollution in sewage polluted bodies of marine and fresh water be found.

Show moreThe significance of the transmission of animal viruses in sewage polluted fresh and marine waters becomes an increasingly important factor as more and more evidence is presented to support the fact that in the case of many viral types one virus particle constitutes an infective dose. Therefore it is very important that a method of determining the extent of viral pollution in sewage polluted bodies of marine and fresh water be found. The longevity of f2 bacteriophage in both marine and fresh water sewage polluted samples was determined, and shown to be 3 to 4 days for marine water and 8 days for fresh water. It was also shown that the culture medium in which the f2 phage was produced, and the larger macromolecular polymers commonly found associated with sewage had a favorable affect in increasing the longevity of f2 phage. It was shown that f2 bacteriophage could be used to follow the initial dispersion of the sewage boil arising from an ocean outfall sewerage system. From these results it was concluded that f2 bacteriophage could be used for more detailed studies concerned with the transmission of viruses in sewage polluted waters.

Show moreTwo methods, a membrane filter-fluorescent antibody technique for detection of Staphylococcus aureus, and isotopic determination of relative heterotrophic activity, were compared with a standard technique based on the recovery of coliform organisms for evaluation as indices of marine pollution. Water samples were collected from coastal areas of Pompano Beach and Boca Raton, Florida. Coliform and staphylococci survival in seawater was studied under laboratory conditions. The effect of exposure to seawater on substrate uptake by coliforms and other sewage microorganisms was studied using isotopic methods. The results of these studies support the feasibility of using S· aureus as a long-range indicator of marine pollution. Under natural conditions, S· aureus appears more resistant to seawater than coliform organisms, although the reverse was found under laboratory conditions. Seawater inhibited uptake of glucose and lactose by Escherichia coli and other sewage organisms. Relative heterotrophic potentials in terms of glucose and lactose uptake velocities were not significantly affected in coastal waters by the influx of bacteria and nutrients in sewage outfall effluent.

Title: Support for Regional Community Anaerobic Digestion for Organic Waste Diversion.
Creator: Sharmin, Sumaiya, Meeroff, Daniel E., Florida Atlantic University, Department of Civil, Environmental and Geomatics Engineering, College of Engineering and Computer Science
Abstract/Description: As the global population is increasing, the generation of various waste materials (fats, oils and grease, fruit waste etc.) is increasing, which when landfilled, takes up valuable landfill space. Anaerobic digestion techniques have been developed that potentially convert these waste materials into energy and fertilizer, thus reducing landfill demand.

Show moreAs the global population is increasing, the generation of various waste materials (fats, oils and grease, fruit waste etc.) is increasing, which when landfilled, takes up valuable landfill space. Anaerobic digestion techniques have been developed that potentially convert these waste materials into energy and fertilizer, thus reducing landfill demand. It has been hypothesized that addition of high strength organic waste to conventional wastewater sludge can enhance the generation of onsite biogas at wastewater treatment plants, to meet the energy requirements of the plant partially or fully. To determine the anaerobic biodegradability of fats, oils and grease and fruit waste residuals, lab scale ultimate digestibility tests were conducted for a period of 63 days under mesophilic conditions. High strength organic wastes, thickened waste activated sludge and inoculum were mixed at 9 different ratios, and the mixtures were incubated in 500 mL serum bottles. After 63 days, the highest methane yield of 280 mL/gVS and 243 mL/gVS were obtained with mixtures containing 10% FOG with 10% red apples and 10% FOG only respectively whereas the methane yield of inoculum was only 8 mL/gVS. Preliminary cost analyses were conducted using the laboratory derived data

Title: Contribution of on-site treatment and disposal systems on coastal nutrient loading.
Creator: Morin, Frederic., Florida Atlantic University, Meeroff, Daniel E., College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
Abstract/Description: When onsite treatment and disposal systems (OSTDS) are not properly sited, they can be a potential risk to public health and a source of environmental degradation. In Florida, OSTDS location has proven to be problematic from a water resources perspective. The objective of this study is to quantify the pollutant loading contributions from OSTDS on coastal canals, with regard to nutrients and pathogens indicators (Total Coliform, E. coli, Enterococcus).

Show moreWhen onsite treatment and disposal systems (OSTDS) are not properly sited, they can be a potential risk to public health and a source of environmental degradation. In Florida, OSTDS location has proven to be problematic from a water resources perspective. The objective of this study is to quantify the pollutant loading contributions from OSTDS on coastal canals, with regard to nutrients and pathogens indicators (Total Coliform, E. coli, Enterococcus). Two similar single-family residential locations were identified: Dania Beach, FL (with 100% OSTDS) and Hollywood, FL (with 100% sewer). Field studies were conducted during the height of the wet and dry seasons. During the wet season, surface water quality of the canal was affected by an OSTDS contribution with higher levels of nutrients and pathogens indicators. During the dry season, no OSTDS impact was detected. OSTDS appear to work properly during the dry season.

Show moreThis study was undertaken to determine the distribution and possible source of Staphylococcus aureus, s. epidermidis, other Micrococcaceae , and enterococci recovered from samples of water collected at the following locations: the Pompano Beach sewage outfall, the Intracoastal Waterway, 5 miles due east of the Boca Raton Inlet, over the 65 ft Boca Raton reef, and in 5 ft of water along the Boca Raton beach. It was also of interest to study the feasibility of employing s. aureus as an indicator of fecal pollution in the marine environment. Neither staphylococci nor enterococci were recovered from 5 samples of beach sand collected from the high tide line to the low tide line. Only low concentrations of staphylococci were recovered from samples collected from the Intracoastal Waterway. The staphylococci recovered from the marine locations do not appear to be true marine bacteria. They do not appear to be originating from bathers, beach washings or the Intracoastal Waterway. Sampling was inadequate to reach definite conclusions on the origin of the Micrococcaceae recovered in the ocean. However, these data indicate the staphylococci originate from the Pompano Beach sewage outfall. Staphylococcus aureus appears to be more resistant to the conditions of the marine environment than the other Micrococcaceae, enterococci or other sewage bacteria recovered on Mannitol Salt Agar and m-Enterococcus Agar. The mean per cent recovery of S. aureus increases with increased distances downstream from the outfall to the 65 ft reef and sampling site 5 miles offshore. ~· aureus appears to be a good indicator of fecal pollution in the marine environment. Survival studies of washed cells of a coagulase positive Staphylococcus aureus run in autoclaved sea water and autoclaved Intracoastal water gave mean decimal reduction times of 16.6 hr and 11.4 hr, respectively. Staphylococci were not recovered from Bryothamnion triguetrum,Caulerpa sertularioides f. brevipes, Dasycladus vermicularis or Padina sanctae-crucis. Ten Micrococcaceae recovered from the ocean were not inhibited by extracts prepared from these algae. Intact segments of these algae possessed antibacterial activity against most, if not all of these Micrococcaceae.

Title: The correlations between OSTDS sites and the pollution of the surface water bodies in Broward County.
Creator: Rocher, Yvel, Bloetscher, Frederick, Florida Atlantic University, College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
Abstract/Description: Sampling data of many surface water bodies in Broward County tend to reveal abnormal levels of bacterial concentrations for total coliform, Escherichia coli and Enterococcus. Given the presence of septic systems in geohydrologically sensitive areas throughout the County, several studies (Morin 2005 and Bocca 2007) suggested a correlation in the high bacterial densities and the septic sites.

Show moreThis thesis was about finding a recovery method for TiO2, using a TiO2 recovery technology, which was high enough to be economical ($10 - $15 per 1,000 gallons) to be adopted by wastewater treatment plants. When comparing recovery technologies, the top three which were investigated further through experimentation were a centrifuge, sedimentation tank, and microfilter membrane. Upon experimentation and research, the TiO2 recovery efficiencies of these technologies were 99.5%, 92.5%, and 96.3%, respectively. When doing economic analysis on these technologies comparing TiO2 efficiencies and capital and operational costs, the centrifuge was the most preferred economic option. Also, its cost did were in the economical range ($10 - $15/1,000 gallons) which makes even this technology economical. Besides that, important and valuable information about TiO2: settling behavior, particle size and zeta potential, interactions with COD, and filter operations (particle characterization) were discovered for future research and future testing on this issue.

Show moreEffluent from on-site sewage treatment and disposal systems (OSTDS) is generally known to impact groundwaters and surface waters with nitrogen (N) and phosphorus (P) and other contaminants. Little research has quantified this problem along the Indian River Lagoon (IRL), especially in Indian River County (IRC) where there are 26,660 active systems. This study assessed the effects of OSTDS on contamination of surface and groundwaters along three urbanized canals and the St. Sebastian River in IRC, all of which flow into the Central IRL. Multiple lines of evidence were used to define the source of the nutrient loadings including the novel approach of using the artificial sweetener, sucralose, as an indicator of human sewage impact. Results indicate that areas with high densities of OSTDS are contributing N to surface waters and elevating N:P ratios through submarine groundwater discharge and promoting eutrophication in the Central IRL.
