  1. 1. Förutsättningar för hantering av länshållningsvatten från tunnelproduktion i byggandet av Ostlänken : Återanvändning av näringsämnen genom bevattning

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Elias Johansson; [2024]
    Nyckelord :Tunnel water; tunnel construction; nitrogen; fertilizer; irrigation; Länshållningsvatten; Tunnelvatten; Tunneldrivning; Kvävegödsel; Bevattning;

    Sammanfattning : When a tunnel is built in rock, a type of water is formed as a residual product. This tunnel wateris formed due to construction processes such as drilling requiring water and groundwater thatinfiltrates into the tunnel. The water can cause environmental damage if it is released directlyinto nature and needs to be treated. LÄS MER

  3. 2. Selected PFAS in the water treatment at the waste-to-energy plant in Umeå : Investigating concentration and composition of selected PFAS in different water treatment steps

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Amanda Carlund; [2023]
    Nyckelord :;

    Sammanfattning : The present study investigated the changes in concentration and composition of five selected PFAS substances in the water treatment at the waste-to-energy plant in Umeå. The five PFAS were PFHxA, PFHpA, PFOA, PFHxS and PFOS. As PFAS exists in a variety of consumer products, they will to some extent end up in waste incineration. LÄS MER

  4. 3. Effects of recirculating water treatment sludge

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Nyckelord :Chemical Engineering; Water and Environmental Engineering; Water Treatment; Coagulation Flocculation; Sludge Recirculation; Technology and Engineering;

    Sammanfattning : Drinking water is crucial in our everyday life. As with many other processes, it is important to produce water of drinking quality in a sustainable manner. This can occur by e.g. LÄS MER

  5. 4. Production of succinic acid by Actinobacillus succinogenes in attached-growth bioreactors and dynamic modelling of biofilm formation

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Henrik Östberg; [2023]
    Nyckelord :Actinobacillus succinogenes; Succinic acid; Biofilm; Attached-growth bioreactor; Dynamic modelling; Cell cultivation; Applied microbiology; Biology and Life Sciences;

    Sammanfattning : Actinobacillus succinogenes is a microorganism is a very efficient producer of succinic acid, a chemical with a wide range of industrial applications. The bacterium is prone to form biofilm, a flocculation of cells attached to a surface. LÄS MER

  7. 5. Evaluation of AI-method for measuring and characterizing particles on-line in drinking water treatment

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Lovisa Ådén; [2023]
    Nyckelord :Turbidimeter; Particle meter; rapid filtration;

    Sammanfattning : The municipal association Norrvatten produces drinking water at Görväln WTP for approximately 700,000 residents in 14 member municipalities in the northern Stockholm region. To ensure the drinking water meets quality criteria, the water must be carefully monitored by the WTP. LÄS MER
