Comparing Phosphorus Removal Efficiencies And Mechanisms Via Two Cost-Effective Specialty Adsorbents In A Cascade Upflow Filtration System, Sydney Kilgus-Vesely Jan 2023

Comparing Phosphorus Removal Efficiencies And Mechanisms Via Two Cost-Effective Specialty Adsorbents In A Cascade Upflow Filtration System, Sydney Kilgus-Vesely

Honors Undergraduate Theses

Finding solutions to treat water that contains phosphorus is an important effort due to the harmful impacts it presents to both human health and the environment. Phosphorus is considered a limiting factor in water oftentimes and therefore controls the growth of algal bloom in a water body. The increase of algal populations due to wastewater effluent, stormwater runoff, and agricultural discharge in Florida waters has a direct link to the event of harmful algal blooms such as red tide in coastal regions, eutrophication of waterbodies, and fish kills. Finding low cost, energy efficient, and low maintenance green sorption media (GSM) …


Development Of Treatment Train Techniques For The Evaluation Of Low Impact Development In Urban Regions, Mike Hardin Jan 2014

Development Of Treatment Train Techniques For The Evaluation Of Low Impact Development In Urban Regions, Mike Hardin

Electronic Theses and Dissertations

Stormwater runoff from urban areas is a major source of pollution to surface water bodies. The discharge of nutrients such as nitrogen and phosphorus is particularly damaging as it results in harmful algal blooms which can limit the beneficial use of a water body. Stormwater best management practices (BMPs) have been developed over the years to help address this issue. While BMPs have been investigated for years, their use has been somewhat limited due to the fact that much of the data collected is for specific applications, in specific regions, and it is unknown how these systems will perform in …


The Effects Of Bam As An Adsorptive Media On Phosphorus Removal In Stormwater, Sultan Salamah Jan 2014

The Effects Of Bam As An Adsorptive Media On Phosphorus Removal In Stormwater, Sultan Salamah

Electronic Theses and Dissertations

To maintain the quality of receiving water bodies, it is desirable to remove total phosphorus (TP) in stormwater runoff. Many media filtration technologies have been developed to achieve TP and soluble reactive phosphorus (SRP) removal. Efficient media adsorption is essential to insure control of stormwater phosphorus inputs to the receiving water body. This project develops and analyzes a functionalized Biosorption Media (BAM) to remove phosphorus species from stormwater runoff. One goal of this project is to find the BAM values for coefficients such as maximum adsorption capacity (QM: 4.35E-05) for the media through SRP isotherm equilibrium experiments using the Langmuir …


Biogeochemical Cycling And Nutrient Control Strategies For Groundwater At Stormwater Infiltration Basins, Andrew M. O'Reilly Jan 2012

Biogeochemical Cycling And Nutrient Control Strategies For Groundwater At Stormwater Infiltration Basins, Andrew M. O'Reilly

Electronic Theses and Dissertations

Elevated concentrations of nutrients, particularly nitrate, in groundwater and springs in Florida are a growing resource management concern. Stormwater infiltration basins, which are a common stormwater management practice in the well-drained karst terrain areas of Florida, are a potentially important source of nutrients to the groundwater system because stormwater exits the basin by only evaporation or infiltration. To better understand the biogeochemical processes integrating stormwater infiltration impacts on groundwater resources in a field-scale setting, a combination of hydrologic, soil chemistry, water chemistry, dissolved and soil gas, isotope, and microbiological data was collected from 2007 through 2010 at two stormwater infiltration …


Assessment Of Aquifer Storage And Recovery Impact On Phosphorus Stability In Lake Sediment, Sha Liu Jan 2010

Assessment Of Aquifer Storage And Recovery Impact On Phosphorus Stability In Lake Sediment, Sha Liu

Electronic Theses and Dissertations

Lake Okeechobee, the second largest natural freshwater lake in the United States, had experienced a historical drought in 2007-2008 and the inflow to Lake Okeechobee has been reduced by 40% of the average daily mean between warm phase and cold phase due to the impact of Atlantic Multidecadal Oscillation in the past six decades. To cope with this water resources management problem, the US Army Corps of Engineers (USACE) proposed the largest national implementation plan of aquifer storage and recovery (ASR) project in the Kissimmee River Basin. Routine operation of ASR will deliver recovered water from ASR wells into the …


The Effectiveness Of Specifically Designed Filter Media To Reduce Nitrate And Orthophosphate In Stormwater Runoff, Mikhal Moberg Jan 2008

The Effectiveness Of Specifically Designed Filter Media To Reduce Nitrate And Orthophosphate In Stormwater Runoff, Mikhal Moberg

Electronic Theses and Dissertations

Throughout Central Florida surface water and ground water are decreasing in quantity and quality in part because of excess Nitrate and Phosphorus nutrients. Stormwater runoff serves as a medium for transport of Nitrate and Phosphorus to surface water and ground water. The goal of this experiment is assess the Nitrate and Phosphorus removal in stormwater using select media. The results of a literature search, batch test experimentation and column test experimentation are used to determine an optimal media blend that may be implemented in detention ponds to reduce Nitrate and Phosphorus. The extensive literature search revealed 32 different media that …


Pilot Study Of Nutrient Loading In A Wet Detention Lake, Eric C. Gurr Jan 2007

Pilot Study Of Nutrient Loading In A Wet Detention Lake, Eric C. Gurr

Electronic Theses and Dissertations

Florida is surrounded by water, and its many internal lakes and rivers have long been recognized for their excellent fishing and boating. This notoriety draws land developers to the lake shores to establish residential and commercial infrastructure. This land development brings with it flood plain alteration, water level stabilization, and increased nutrients which cause adverse impacts to our lakes. In response, the United States Environmental Protection Agency (EPA) passed the Federal Clean Water Act (CWA) in 1972 which set the framework for the water quality standards for the entire United States. As a result of the CWA many point sources …


A Study Of Differences In Vertical Phosphorus Profiles Within The Sediments Of Selected Florida Lakes As Related To Trophic Dynamics, Edgar Allen Stewart Iii Jan 1976

A Study Of Differences In Vertical Phosphorus Profiles Within The Sediments Of Selected Florida Lakes As Related To Trophic Dynamics, Edgar Allen Stewart Iii

Retrospective Theses and Dissertations

Several Florida lakes with different documented trophic state indices were selected for sediment analysis. Vertical sections of the sediment were taken at depths of .1, .5, 1, 2, 3, 4, 5, 6, 10 and l5 centimeters below the surface of the sediment-water interface. Total Phosphorus analysis was done on each section. The profile presented was then evaluated and was found that the profiles best fit the equation Y = X/ (A + BX), where Y is the Phosphorus Concentration in ppm and X is the sediment depth in cm. Correlation between the trophic state and the profiles characteristics are presented. …
