  1. 31. 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. 32. Continuous leaching of phosphorus from sewage sludge ash

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Sofie Göransson; [2022]
    Nyckelord :Ash leaching; Continuous stirred tank reactor; CSTR; Phosphorus recovery; Sewage sludge ash;

    Sammanfattning : The global demand for food is increasing. Different nutrients are used to increase growth in agriculture and are thus essential for the world ́s food supply. An important and common nutrient is phosphorus. It can be mined, in the form of phosphate, from phosphate rock. LÄS MER

  4. 33. Techno-economic evaluation of hydrochar via hydrothermal carbonisation of organicresidues

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Abdirahman Abdullahi; [2022]
    Nyckelord :Technoeconomic analysis; energy system modelling; HTC; hyrochar; system integration; OSMET;

    Sammanfattning : This thesis has investigated the techno-economic feasibility of upgrading the sludge from a chemical pulp mill to hydrochar via hydrothermal carbonization (HTC). The intended use of the hydrochar was to replace fossil coal within metallurgical applications in the iron and steel industry. LÄS MER

  5. 34. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Fanny Blom; [2022]
    Nyckelord :wastewater treatment; primary treatment; biogas potential; primary settling treatment; rotating belt filter; chemically enhanced primary treatment; environmental engineering; water resources engineering; Technology and Engineering;

    Sammanfattning : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. LÄS MER

  7. 35. Potentialen hos hydrokol från avloppsslam som jordförbättringsmedel

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Lina Akhlaghi; [2022]
    Nyckelord :Hydrothermal carbonization; hydrochar; soil improvement; pyrolysis; biocoal;

    Sammanfattning : Margretelunds reningsverk i Åkersberga står såsom andra svenska avloppsreningsverk inför nya utmaningar i samband med anpassningen till ett mer hållbart och cirkulärt samhälle. För att bidra till en bra lokal miljö med få transporter och minimerad lukt, uppnå en hög grad av fosforåtervinning, samt reducera organiska och icke-organiska föreningar i slammet ska Roslagsvattenb i samarbete med IVL Svenska Miljöinstitutet utvärdera C-Greens OxyPower HTC-teknik.
