  1. 1. Modeling PFAS Transport in Groundwater - Exploring current approaches and evaluating parameter importance

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

    Författare :Clara Eklund; [2023]
    Nyckelord :PFAS; Groundwater modeling; FEFLOW; Python; Machine learning; Technology and Engineering;

    Sammanfattning : PFAS contamination in drinking water is a current problem, and new regulations for drinking water limits were recently implemented in each member country of the EU in January this year. Understanding the spread of PFAS in groundwater is therefore important to prevent it from reaching drinking water sources. LÄS MER

  3. 2. Hydraulic Modeling and Quantitative Microbial Risk Assessment of Intrusionin Water Distribution Networks Under Sustained Low-Pressure Situations

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Maryam Shakibi; [2022]
    Nyckelord :drinking water distribution network; EPANET; hydraulic modelling; low pressure; pathogen intrusion; Quantitative Microbial Risk Assessment QMRA ; distributionsnät för dricksvatten; EPANET; hydraulisk modellering; lågtryck; patogen inläckage; Kvantitativ mikrobiell riskbedömning QMRA ;

    Sammanfattning : Drinking water systems aim to remove, reduce, and prevent microbial contamination in water by usingmultiple barriers from catchments to consumers. Water distribution networks are vulnerable tocontamination from external sources if they lose their physical or hydraulic integrity. LÄS MER

  4. 3. Simulation strategies for improved contamination modeling of liquid dynamics on automotive surfaces

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Thisal Mandula Sugathapala; Twan Bakker; [2022]
    Nyckelord :Volume of Fluid; Contamination modeling; Blended Kistler model; Dynamic contact angle models; Exterior water management; Light-induced fluorescence imaging; Multiphase flows; Surface flows; Computational fluid dynamics; Sensor soiling;

    Sammanfattning : A significant level of research is currently being carried out in the development of driver support systems as they are expected to play a key role in minimizing road vehicle accidents and creating a safe driving environment under harsh weather conditions. However, the performance of some components used by existing driver support systems like LIDAR and visual cameras are affected by extreme weather conditions such as heavy rain fall and snow. LÄS MER

  5. 4. Techno-economic feasibility study of PVT collector coupled with heat pump for membrane distillation water purification in rural India

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Erik von Schultz; [2022]
    Nyckelord :Photovoltaic-thermal; Heat pump; Membrane distillation; Off-grid; Water purification; AGMD; Solhybridpaneler; Värmepump; Membrandestillation; Off-grid; Vattenrening; AGMD;

    Sammanfattning : India is experiencing a bitter challenge in terms of water resources, with the lack of access to safe drinking water being attributed to nearly 200 000 deaths per year. The rural population is especially exposed as groundwater make up 85 % of their drinking water, with widespread contamination being reported. LÄS MER

  7. 5. Modeling the microbial fate and transport in rivers of South Africa

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Stina Perman; [2021]
    Nyckelord :Water quality modelling; HYPE; waterborne pathogen transport; microorganism; E. coli; Vattenkvalitetsmodellering; HYPE; vattenburna patogener; mikroorganism; E. coli;

    Sammanfattning : In recent years, surface water used for domestic, industrial, and irrigation purposes in South Africa has deteriorated due to inadequate wastewater treatment, urban and agricultural runoff, and rural settlements with deficient sanitation. Access to safe drinking water and sanitation is a basic human right, and if waterborne pathogens are present in the water environment, they compose a human health risk. LÄS MER
