  1. 1. Study of mixing and exchange in a drinking water reservoir using CFD modeling

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Nadja Rabizadeh; [2023]
    Keywords : CFD; Fluid Mechanics; OpenFOAM; drinking water reservoir; URANS; transient; exchange of water; mixing; Norrvatten;

    Abstract : This thesis examines water mixing and exchange in a drinking water reservoir operated by themunicipal association Norrvatten. Recent water samples from the reservoir’s outgoing waterhave shown an increase in culturable bacteria during late summer and fall. READ MORE

  3. 2. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ebba Pegestam; [2022]
    Keywords : Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

    Abstract : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

  4. 3. Energieffektivisering av dricksvattendistribution : dataanalys och simulering av pumpdrift vid Görvälns vattenverk

    University essay from SLU/Dept. of Energy and Technology

    Author : Anton Thorstensson; [2020]
    Keywords : norrvatten; förbrukningsprognos; renvattenpumpar; högreservoarer; vattentorn; fyllnadskrav;

    Abstract : This project investigates the efficiency of the water distribution system from Görväln's pumping station to Norrvatten's central consumption zone. The goal is to propose actions that lead to enhanced energy efficiency. READ MORE

  5. 4. Technical Possibilities of Wastewater Reclamation for Potable Use in Hurva, Scania : Regarding the Waterbalance and From a Process Technical Point of View

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Esmeralda Frihammar; [2020]
    Keywords : Potable Wastewater Reclamation; Re-use; VA SYD; WWTP; DWTP; Återanvändning; avloppsvatten; cirkulära vattensystem; dricksvattenverk; reningsverk; VA SYD;

    Abstract : During recent years both Sweden and the rest of Europe have experienced periods of drought as a consequence of hot summers with low levels of precipitation. For villages provided with drinking water from water plants with groundwater as raw water source droughts can lead to considerable problems if the groundwater reservoir would be affected. READ MORE

  6. 5. Energy losses in hydraulic systems of water treatment plants: An application to Vombverket in south Sweden

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Ssenozi Ivan; [2016]
    Keywords : Hydraulic system; Energy losses; Local losses; Discharge; Fittings; Pipes; Pipe Flow Expert Model; Loop; Friction losses; Technology and Engineering;

    Abstract : Sydvatten AB is a municipally owned company producing and supplying drinking water to about 900,000 inhabitants in southern Sweden through two water treatment plants (WTP), Ringsjöverket and Vombverket. At Vombverket, the present capacity is somewhat reduced because of pressure losses in the pipe systems of the WTP. READ MORE
