  1. 1. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Mehrzad Ghassemi; [2022]
    Nyckelord :Greywater; EBPR; Phosphorus; Biological treatment; Water and environmental engineering; Technology and Engineering;

    Sammanfattning : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes.

  3. 2. Fältstudie om kalciums betydelse för potatisens skalkvalitet och lagringsförmåga

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Maria Weigl; [2022]
    Nyckelord :potatiskvalitet; skalfinish; kalcium; odling; mangan; zink; potatis;

    Sammanfattning : Peel quality of the potato tuber is becoming increasingly important in potato cultivation. Consumers primarily demand potatoes that have an even, smooth, and fine peel. Tubers that have different types of scabs or other stains are rejected. In addition, farmers get paid more at higher peel quality. LÄS MER

  4. 3. En förstudie om näring- och energiåtervinning från källsorterande avloppssystem

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Sebastian Gisle; [2021]
    Nyckelord :hållbarhet; återvinning; resurshantering;

    Sammanfattning : The world's demand for nitrogen and phosphorus is increasing at the same time as high concentrations of the nutrients flow out from water treatment plants. The presence of nitrogen and phosphorus in nature is a contributing factor to eutrophication and thus damages ecosystems. LÄS MER

  5. 4. Technical Lignin Characterization of Acacia crassicarpa and Eucalyptus Hybrids

    Master-uppsats, KTH/Träkemi och massateknologi

    Författare :Lutfi Difi Rosta; [2021]
    Nyckelord :Lignin; Acacia crassicarpa; Eucalyptus Hybrids; kraft cooking; kraft dissolving pulp cooking; Lignin; Acacia crassicarpa; Eucalyptus Hybrids; kraftkokning; kraftupplösning av massa;

    Sammanfattning : Lignin är en av de vanligaste naturliga råvarorna på jorden och finns mestadels i trä. Nuförtiden är valoriseringen av lignin en av processutvecklingarna för teknologier inom massa- och pappersindustrin. Denna utveckling syftar till att öka värdet av lignin. LÄS MER

  7. 5. Black phosphorous sample preparation for ultrafast electron diffraction studies

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Rebecca Ahrling; [2020]
    Nyckelord :Graphene; Black phosphorus; electron diffraction; 2D material; Technology and Engineering;

    Sammanfattning : Since 2004 when mechanical exfoliation was first utilised to produce single layered samples of graphite, 2D materials have gained interest in the scientific community. With the prerequisite that the initial bulk material has a layered structure, these 2D materials have created an opportunity to examine materials on a very small scale as well as opening the possibility of creating smaller electrical components for industrial and commercial use, with well-known and documented parameters.
