  1. 21. 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.

  3. 22. GAC filter Design Criteria for Wastewater Treatment for Removal of Organic Micropollutants – A Literature Review

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Bhargav Reddy Elavarthi; [2021]
    Keywords : micropollutants; activated carbon filtration; empty bed contact time EBCT ; pharmaceuticals; breakthrough curves; adsorption; PFOS; carbon use; water and environmental engineering; Technology and Engineering;

    Abstract : Granular Activated Carbon (GAC) is nowadays suggested as a fourth (quaternary) treatment step at municipal wastewater treatment plants to remove certain chemicals and particularly organic micropollutants (OMPs). This work investigated the different factors that affect the performance of the GAC filter for the removal of micropollutants in a municipal wastewater treatment plant. READ MORE

  4. 23. Photoredox catalysis enabled C–O bond activation: Access to unnatural amino acids

    University essay from KTH/Kemi

    Author : Josefin Lantz; [2021]
    Keywords : photoredox catalysis; unnatural amino acids; alkyl oxalate; visible light; radicals; fotoredoxkatalys; icke-naturliga aminosyror; alkyloxalat; synligt ljus; radikaler;

    Abstract : Fotoredoxkatalys tillhandahåller möjligheter att utveckla nya hållbara kemiska reaktionsvägar. När fotokatalysatorn bestrålas med synligt ljus möjliggörs elektronöverföring till eller från substratet som i sin tur medför alstring av reaktiva fria radikaler. READ MORE

  5. 24. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Virginia Tosi; [2021]
    Keywords : Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

    Abstract : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

  6. 25. Investigating Minor States of the Oncoprotein N-MYC, with Focus on Proline Cis/Trans Isomerisation using NMR Spectroscopy

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Frida Haugskott; [2021]
    Keywords : Myc; N-Myc; Intrinsically Disordered protein IDP ; Proline; cis-trans isomerisation; minor conformation; NMR; cancer;

    Abstract : MYC is a family of three regulator genes that codes for transcription factors. Expression of Myc proteins from MYC genes is found to be deregulated in 70 % of all cancer forms. The three human homologs C-Myc, N-Myc and L-Myc are mainly associated with cancer in the lymphatic system, nerve tissues and lung cancer, respectively. READ MORE
