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. Evaluation of PFAS removal from nanofiltration membrane concentrate using foam fractionation

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : William Stefansson; [2022]
   Keywords : PFAS; Aeration foam fractionation; Nanofiltration membrane; DWTP; Surfactant; PFAS; Skumfraktionering; Nanofiltration; Vattenverk; Surfaktant;

   Abstract : Per- and polyfluorinated substances (PFASs) have become an urgent topic in the water treatment industry in recent years as a consequence of new scientific discoveries of the correlation between the ingestion of some PFASs and their toxicity in humans and other organisms. PFASs are synthetic compounds present in a variety of products. READ MORE

4. 3. Potential of waste-derived VFAs-bearing effluents as an external carbon source for MBBR denitrification of domestic wastewater

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Seyed Reza Manafi Khosroshahi; [2022]
   Keywords : Volatile fatty acids; Denitrification; Wastewater treatment; Biological nutrient removal; Nitrate removal; Electron accepter; Carbon source; Electron doner; Moving bed biofilm reactor; Nanofiltration; VFA concentration; Discharge standards; Carriers; acclimatization; VFAs; MMBR; NF; WWTP; BNR;

   Abstract : In conventional wastewater treatment plants, methanol, ethanol, and acetate are used as carbon source for the denitrification process in the biological nutrient removal. However, growing concern regarding economical costs and carbon footprints from the fossil-based production of these chemicals have forced the companies to look for other alternatives. READ MORE

5. 4. Cradle-to-Gate LCA of Water Treatment Alternatives : A case study performed for Norrvatten’s future waterwork expansion

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Siddharth Selvarajan; [2021]
   Keywords : Life cycle assessment; Water purification method; Potable water production; Microbiological barrier; Activated carbon; Sludge separation; Livscykelbedömning; Vattenreningsmetod; Produktion av dricksvatten; Mikrobiologisk barriär; Aktivt kol; Slamavskiljnin;

   Abstract : Norrvatten is a municipal association which owns a water treatment plant capable of supplying good quality drinking water to the consumers in the associated neighbouring municipalities. After preliminary investigations for the future year of 2050, there were estimates which suggest a potential water quality degradation in the lake which supplies the raw water for treatment due to uncertain future climatic conditions and other forms of pollutions from the surrounding.
