  1. 1. Considerations and Novel Technologies in Industrial Water Treatment - Treatment of challenging wastewater

    University essay from KTH/Kemiteknik

    Author : Nils Toll; [2021]
    Keywords : Industrial water treatment; considerations; novel technologies; BOD; COD; organic waste; heavy metals; desalination; Industriell vattenrening; nyckelfaktorer; nya teknologier; organiskt avfall; tungmetaller; avsaltning;

    Abstract : Industriell vattenrening är ett extremt viktigt område inom Miljöskyddsteknik då 60% av allt sötvatten inom Sverige används av industrier. Substanser som PFAS, aromatiska textilfärger, fenol och läkemedelsrester är extra utmanande då dessa kan vara gifta för biologisk rening. READ MORE

  4. 4. Evaluation of Dissolved Air Flotation for Water Purification: With Focus on Floc Characteristics and PFAS

    University essay from KTH/Kemiteknik

    Author : Ludwig Löf; [2021]
    Keywords : Water treatment; Sedimentation; Flotation; PFAS; Zeta potential; Vattenbehandling; Sedimentering; Flotation; PFAS; Zeta potential;

    Abstract : I detta projekt har experiment utförts med mål att förse kommunalförbundet Norrvatten med data som kan användas som underlag för beslutsfattande angående om deras fällningslinjer i vattenreningsprocessen ska köras i flotation eller sedimentering. För detta ändamål har koncentrationen av poly- och perfluorerade alkylsubstanser (PFAS) samt karaktär av agglomererade partiklar (flockar) undersökts och jämförts mellan fällningslinjer som körs i olika konfigurationer.

  5. 5. A valuation of ecosystem services from blue-green infrastructure for stormwater management

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sofia Anderzon; [2021]
    Keywords : Stormwater; blue-green infrastructure; urban ecosystem services; indicators; semi-quantitative valuation; Dagvatten; dagvattenhantering; blågrön infrastruktur; urbana ekosystemtjänster; indikatorer; semi-kvantitativ värdering;

    Abstract : The ongoing urbanization leads to densification and growth of cities, which replaces natural areas with hard surfaces. Precipitation is then more likely to runoff as stormwater than to be detained locally. Also, precipitation is predicted to be increasing as an effect of climate change. READ MORE
