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

    University essay from KTH/Skolan för teknikvetenskap (SCI)

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

    Abstract : 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.

  2. 12. Finding ways of optimizing coagulant dosage, for a more sustainable wastewater treatment process

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Hanna Sjöman; [2023]
    Keywords : Wastewater treatment process; coagulant dosage; COD; machine learning; water and environmental engineering; Technology and Engineering;

    Abstract : The wastewater treatment process at Oatly consists of several treatment steps of which, two are chemical treatment steps involving coagulation followed by flotation to remove phosphorous and COD. The coagulant dosage is mainly determined based on the operator’s experience and supported using results from jar tests. READ MORE

  3. 13. Washing efficiency in the pulp mill : An evaluation of the washing efficiency in SCA Munksund's pulp mill

    University essay from KTH/Fiber- och polymerteknologi

    Author : Malin Malmberg; [2023]
    Keywords : Chemical Pulp; Lignin; COD; Pulp Washer; Kraft Pulping; Pappersmassa; Lignin; COD; Massatvätt; Sulfatmassaprocessen;

    Abstract : Munksunds pappersbruk är ett integrerat massa- och pappersbruk som består av två fiberlinjer, en barr- och en lövlinje där båda kokarna är kontinuerliga med efterföljande tvättsteg. En kartering av COD (eng. Chemical Oxygen Demand) och natrium utfördes för båda linjerna för att utvärdera tvätteffektiviteten. READ MORE

  4. 14. Evaluation of The Impact of Automated Driven Vehicles on Traffic Performance at Four-leg Signalized Intersections

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Author : Ahmed Osman; [2023]
    Keywords : Automated driven vehicles; Microscopic simulation; PTV VISSIM; Traffic performance; signalized intersection;

    Abstract : Intersections, particularly four-leg signalized intersections, are frequent sites of traffic congestion in urban areas. This congestion can lead to delays, increased travel time, and a negative impact on traffic performance and quality of life for people. READ MORE

  5. 15. Improving network performance with a polarization-aware routing approach

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jingyi Pan; [2023]
    Keywords : Traffic engineering; Hash function; Multipath routing; Trafikteknik; Hash-funktion; Flervägsdirigering;

    Abstract : Traffic polarization in networks refers to the phenomenon where traffic tends to concentrate along specific routes or edges when doing multipath routing, leading to imbalanced flow patterns. This spatial distribution of traffic can result in congested and overburdened links, while other routes remain underutilized. READ MORE
