  1. 1. Faradaic Reactions in Capacitive Deionization : A Comparison of Desalination Performance in Flow-through Cell Architectures

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

    Författare :John Bradley; Miranda Carlström; [2023]
    Nyckelord :Capacitive deionization; Faradaic reactions; Flow-through CDI; Upstream anode; Downstream anode; Desalination Performance; pH fluctuations;

    Sammanfattning : Capacitive Deionization (CDI) is an energy-efficient desalination technology that utilizes an electric field to extract ions from water. Flow-through CDI systems show potential for superior desalination performance compared to traditional flow-by CDI; however, they face the challenge of increased occurrence of Faradaic reactions, leading to undesired by-products and reduced energy efficiency.

  3. 2. Extraction and optimization for modeling ofdesalination by capacitive deionization

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

    Författare :Max Rehman Linder; Zeshen Bao; [2023]
    Nyckelord :Desalination; Capacitive Deionization; ELC model; Adsorption; Simulation;

    Sammanfattning : Water scarcity is set to become a big challenge in the 21st century and more efficient desalinationtechnologies will be needed in the future. In this project, one desalination method called capacitivedeionization (CDI) is explored and we used a model called the ELC model to simulate CDI withComsol. LÄS MER

  4. 3. Application of electrodes with redox mechanisms for the desalination of water

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

    Sammanfattning : Capacitive deionization is a promising technology for purification and desalination of brackish water with great advantages over current technologies due to its low operating cost and high-water recovery ratio. Most of the system studied relies on the adsorption/desorption capacity of activated carbon electrodes due to its high surface area. LÄS MER

  5. 4. Characterization of Cobalt Prussian Blue Analogue in Capacitive Deionization

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

    Författare :Zaid Akrawi; Twana Hassan Cheragwandi; [2022]
    Nyckelord :capacitive deionization; CDI; water purification; Prussian Blue; electrochemistry;

    Sammanfattning : Clean, drinkable water is nowadays taken for granted in most developed coun-tries. However, over two billion people in the world do not have access to drink-ing water. In an attempt to combat this, capacitive deionization (CDI) hasgained increased attention in recent years. LÄS MER

  7. 5. Validering av ny vattenrenings teknik

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

    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
