  1. 1. Techno-Economic Analysis of Dye Separation in Textile Recycling

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : David Lundberg; [2024]
    Keywords : Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

    Abstract : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. READ MORE

  3. 2. Predicting inflow and infiltration to wastewater networks based on temperature measurements

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Martin Åsell; [2024]
    Keywords : Inflow and Infiltration; I I; CNN; Linear regression;

    Abstract : Sewer pipelines are deteriorating due to aging and sub optimal material selections, leading to the infiltration of clean ground and rainfall water into the pipes. It is estimated that a significant portion (up to 40-50%) of the water entering wastewater treatment plants is actually clean infiltrated water. READ MORE

  4. 3. The Potential of Dissolved Air Flotation for PFAS Reduction in Norrvatten's Future Waterworks

    University essay from KTH/Kemiteknik

    Author : Madeleine Vikström; [2023]
    Keywords : PFAS4; drinking water production; dissolved air flotation; granular activated carbon filter; sludge management; PFAS4; dricksvattenproduktion; flotation; granulärt aktivt kolfilter; slamhantering;

    Abstract : Norrvatten är en av Sveriges största dricksvattenproducenter. Med ett ökande behov av en större produktionskapacitet och nya regleringar, planerar dem att förbättra sin reningsprocess. En aspekt som kräver omfattande undersökning är val av reningsmetod för att nå den nya gränsen från Livsmedelsverket för fyra PFAS kemikalier. READ MORE

  5. 4. Experimental Study of Flow Fields in Moving Bed Biofilm Reactors

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Shea Nee Chew; [2023]
    Keywords : Moving bed biofilm reactors; Biofilm carriers; Mechanical mixing; Mixer configurations; Carrier mixing; Biofilmsreaktorer med rörlig bädd; Biofilmsbärare; Mekanisk blandning; Blandarkonfigurationer; Bärarblandning;

    Abstract : With the rise in global energy prices, as well as energy consumption being the largest source of greenhouse gas emissions, biofilm-based systems utilized for wastewater treatment, such as moving bed biofilm reactors (MBBRs), have grown in popularity for their lower energy consumption compared to conventional activated sludge processes. However, this technology requires large amounts of energy to constantly distribute and suspend its biofilm carrier within the reactor by either aerators or mechanical mixers. READ MORE

  6. 5. Biogas Potential in the North of Sweden : Inventory and Techno-Economic Assessment of Substrates for an Increased Biogas Production in Norrbotten

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Alma Fahlén Hammar; [2023]
    Keywords : Biogas; anaerobic digestion; AD; Norrland; bioenergy; fossil-free; chemical engineering; Chemistry; Technology and Engineering;

    Abstract : Great investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the production of alternative energy sources needs to intensify.
