  1. 1. A Quantitative Microbial Risk Assessment Associated with Cross-Connections in the Drinking Water Network in Combination with Hydraulic Modeling

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Fatin Alzuhairi; [2022]
    Nyckelord :EPANET; QMRA; Water distribution network; Health risk analysis; Cross-connections and backflow; Low pressure; Water quality; Simulation; Pathogen; EPANET; QMRA; vattendistributionsnät; hälsoriskanalys; korskoppling; lågtryck; vattenkvalitet; simulering; patogen;

    Sammanfattning : Drinking water companies have the technology and responsibility to deliver safe and high-quality drinking water to the water distribution systems network (WDN). However, many events within the WDN, such as cross-connections and backflow, might degrade water quality and pose public health risks to consumers. LÄS MER

  3. 2. IoT Buoy for Water Quality Monitoring : Design, prototype, and test of a solar-powered, LoRaWAN-based WQM system for the smart city

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Mattia Dalla Via; [2021]
    Nyckelord :IoT; LPWAN; Water Quality Monitoring; Environmental Monitoring; Smart City;

    Sammanfattning : Although water is incredibly abundant on Earth, only 2.5 % of the water reserve is freshwater, and one third of the world’s population lacks safe drinking water. Water quality monitoring (WQM) is thus a crucial asset to safeguard this invaluable resource. LÄS MER

  4. 3. The biodegradable straw - Investigating how enzymes can be used to enhance desired product qualities of drinking devices.

    Master-uppsats, Lunds universitet/Innovation

    Författare :Charlotte Parnefjord Gustafsson; Hanna Liang; [2020]
    Nyckelord :biodegradable; bioplastics; drinking devices; enzymes; fibre material; PHA; product design; statistical analysis; straws; Technology and Engineering;

    Sammanfattning : The increasing production of single-use plastics negatively affects the climate. The resulting plastic ocean debris has fatal consequences to marine life. As a result, the European Parliament has placed a ban on single-use plastics by 2021, making it essential to study sustainable materials for single-use products such as straws. LÄS MER

  7. 5. Validering av ny vattenrenings teknik

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Algot Rickman; [2019]
    Nyckelord :;

    Sammanfattning : Tillgång till rent vatten är en mänsklig rättighet. Med klimat förändringar som orsakar en förändring i regn mönster över hela planeten skapas underskott av dricksvatten under svenska somrar. Avsaltning av Östersjövatten kan lösa många av de problem som har orsakats av vatten brist. LÄS MER
