    Keywords : nickel; sulfide; sulphide; groundwater; modeling; mass transport; Feflow; Umeå; nickel; sulfid; monosulfid; grundvatten; modellering; masstransport; Feflow; Umeå;

    Abstract : The raw water in some of Umeå's abstraction wells has shown high nickel levels for more than a decade. The cause has not been determined but there is an investigation from 2010 where the results indicate sulphide clay found adjacent to two basins used for artificial infiltration. READ MORE

  3. 2. Evaluation of The Viral Reduction Potential using Ultrafiltration Membranes in the Drinking Water Treatment Process at Norrvatten

    University essay from KTH/Industriell bioteknologi

    Author : Emma Eriksson; [2023]
    Keywords : Microbiological barrier; Ultrafiltration; NanoCeram filter; Drinking Water; Raw Water; Mikrobiologisk barriär; Ultrafiltering; NanoCeram filter; Dricksvatten; Råvatten;

    Abstract : En pilotanläggning för ultrafiltering testas nu i Norrvattens reningsprocess för att undersöka ifall den kan användas som en tredje mikrobiologisk barriär i reningsprocessen. Målet med detta projekt är att testa membranets kapacitet att filtrera bort viruspartiklar men även membranet generella reduktionsförmåga för andra mikrobiologiska och kemiska kontamineringar.

  6. 5. Open Waters - Digital Twins With use of Open Data and Shared Design for Swedish Water Treatment Plants

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Michael Nyirenda; [2020]
    Keywords : Water treatment; Digital twin; open data; Industry 4.0; decision support system; Vattenrening; digitala tvillingar; öppen data; industri 4.0; beslutsunderlagssystem;

    Abstract : Digital twins (DTs) are digital copies of a physical system that incorporates the system environment, interactions, etc. to mirror the system accurately in real time. As effective decision support systems (DSS) in complex multivariate situations, DTs could be the next step in the digitalization of water management. READ MORE
