  1. 6. CHILLER DIAGNOSTICS Machine learning approach Carrier

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Vilius Koegst; Tatiana Orlova; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Chillers are large and complex machines that are used for temperature regulation in large buildings and plants. An undetected fault in the machine can lead to extended downtime and cause both great financial losses and increased environmental impact. LÄS MER

  3. 7. Techniques for characterization and quantification analysis of foulant deposition in Alfa Laval’s high-speed separators : A literature study

    Kandidat-uppsats,

    Författare :Mwansa Benaya; Henrik Dahlén; Emil Axelsson; Cassandra Liljekvist; Maja Nordell; [2022]
    Nyckelord :Dairy foulant; Marine foulant; Characterization; Quantification; Stainless steel; surface; analysis;

    Sammanfattning : Alfa Laval is a global company that provides solutions, products, and services for industry, such as high-speed separators for marine and food-application. Foulant deposition on the stainless-steel surfaces of Alfa Laval’s high-speed separators has shown to result in lowering of the separation efficiency. LÄS MER

  4. 8. Ultrasonication of Spiral Wound Membranes to Mitigate Fouling in Reverse Osmosis

    Master-uppsats, KTH/Kemiteknik

    Författare :Eliot Diklev; [2022]
    Nyckelord :Reverse Osmosis; Spiral Wound Membrane; Ultrasonication; Fouling; Omvänd Osmos; Spirallindat Membran; Ultraljudsbehandling; Igenslamning;

    Sammanfattning : Syftet med den här studien var att undersöka en alternativ slamningsreducerande teknik till spolning, som effektivt kan ta bort biologisk påväxt. Ultraljud undersöktes som en möjlig metod för att ta bort igenslamningen från omvänd osmos med ett spirallindat membran. LÄS MER

  5. 9. Energieffektivisering av membranluftrengöring vid högflödesperioder : Studie på en storskalig MBR-pilot på Syvab Himmerfjärdsverket i samarbete med SUEZ Water Technologies and Solutions

    Master-uppsats, Karlstads universitet

    Författare :Patrik Bou-Rached; [2022]
    Nyckelord :MBR; membrane air scouring; trans membrane pressure; luftflöde; membranluftrengöring; transmembrantryck;

    Sammanfattning : Membrane BioReactor (MBR) is a wastewater treatment method which combine both biological and physical cleaning. In the membrane tank there is membrane fibres which physically separate wastewater from containing organic material. This causes the membrane fibres to easily build fouling. LÄS MER

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

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

    Sammanfattning : 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. LÄS MER
