EVALUATING THE PERFORMANCE OF A DISTRICT-SCALE GEOTHERMAL EXCHANGE SYSTEM

Heeg, Evan (2024-05-10)

In this thesis the performance of a district-scale geothermal exchange (GHX) system near Madison, WI (USA) is evaluated. GHX systems send an exchanger fluid underground through pipes and utilize the relatively constant ...

Evaluating the compatibility of solvents used in reductive lignin depolymerization with microbial funneling using Novosphingobium aromaticivorans

Scholz, Samuel (2023)

The industrial revolution has resulted in the intensive use and dependence of fossil fuels and their products around the world. Fossil fuel emissions and the accumulation of carbon dioxide in the atmosphere are causing ...

Impacts of managed aquifer recharge on ecosystem services in a forested and agricultural landscape

Barker, Harold (2023)

Groundwater is a crucial global resource that millions rely on daily. Groundwater provides reliable sources of drinking water, supports ecosystems through maintaining streamflow and wetland habitats, and further provides ...

USING SCADA AND AMI TO IDENTIFY AREAS OF WATER LOSS IN MADISON WATER UTILITY

Reams, Isabel (2023)

Madison Water Utility (MWU) has an annual water loss of approximately 12%. This accounts for roughly 1.1 billion gallons of water and 2500 MWh of electricity per year. The electricity used to pump this lost water contributes ...

Aeration Optimization at Beloit Wastewater Treatment Plant through Predictive Nutrient Loading via AI-Predicted Daily Averages and Logic Control

Wahl, Jack (2023)

The growing global demand for clean water highlights the importance of improving the efficiency of wastewater treatment processes to reduce energy consumption and promote sustainability. With the European Union's objective ...

Cumulative Impacts to Bluff Recession in the vicinity of Coastal Structures under Fluctuating Water Levels in Lake Michigan

Tryon-Petith, Miles (2023)

Cumulative impacts of coastal recession in the United States impact critical infrastructure, threaten the safety of 127 million lives, the security of over $9 trillion in goods and services, and 80,000 acres of wetlands. ...

QUANTITATIVE ANALYSIS OF IMIDACLOPRID IN ENVIRONMENTAL WATER MATRICES BY SURFACE-ENHANCED RAMAN SPECTROSCOPY

Cai, Shiqing (2023)

Neonicotinoids are synthetic pesticides commonly employed in agricultural fields to combat pests. Due to their high water solubility and persistence, they can be transported via percolating water or runoff into groundwater ...

I Can Reach My Full Potential with a Little Help from My Friends: Understanding Construction Project Team Dynamics and Performance Through Personality Profiling

Limberg, Calob (2023)

Over six trillion dollars were spent in the global construction market in 2020 (Global Construction Market Size 2020-2030 2022). This number is both significantly larger than a decade ago, and yet a fraction of what it is ...

Evaluating the anti-fouling performance of electrochemically active nickel based membrane

Majumder, Samarpan Deb (2023)

Fouling is inevitable for membrane-based processes. To increase longevity of membranes, anti-fouling mechanisms are crucial. Current anti-fouling mechanisms are often chemical-intensive, expensive and are known to hinder ...

CHARACTERIZING THE ENVIRONMENTAL FATE OF AQUATIC HERBICIDES BY CONNECTING QUANTIFICATION IN LAKES TO LABORATORY STUDIES

Van Frost, Sydney (2023)

Aquatic herbicides are a class of organic compounds that are used in surface water bodies to manage the persistence of invasive and nuisance aquatic plants. Understanding their degradation and transformation pathways are ...
