  1. 16. UV-based advanced oxidation process for nutrient stabilisation and organic micropollutant degradation in source-separated human urine

    Författare :Natnael Demissie; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Urine dehydration is one of the technological approach to recover nutrients in concentrated form from source separated urine. When drying fresh urine, nitrogen loss occurs due to hydrolysis of urea into ammonia unless methods to inactivate urease enzyme are employed. LÄS MER

  3. 17. Unsaturated Phase Environmental Processes in MSWI Bottom Ash

    Författare :Aamir Ilyas; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bottom Ash; Frequency Domain; Hydrogen Recovery; Leaching; Microbial Respiration; Eco-toxicity; Solid Waste;

    Sammanfattning : Every year, Sweden produces 1.5 million tons of incineration residues from waste to energy plants. Among these residues bottom ash(BA) due to its large volume and good geotechnical quality can be reused as an alternative construction material. LÄS MER

  4. 18. Alkaline Urine Dehydration : how to dry source-separated human urine and recover nutrients?

    Författare :Prithvi Simha; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Human urine is a renewable resource from which water, nutrients and energy can be recovered and safely recycled. This thesis presents a novel on-site technology, called alkaline dehydration, for recovering nutrients from source-separated urine. LÄS MER

  5. 19. On leachate emissions from municipal solid waste

    Författare :Martijn van Praagh; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeology; Miljöstudier; Environmental studies; Environmental Impact; heavy metals; Organic carbon; teknisk geologi; Hydrogeologi; geographical and geological engineering; teknisk geografi;

    Sammanfattning : When attention is drawn to the recovery of resources within waste, the amount and types of waste disposed of at landfills change. A waste management system based on separate kerbside collection, sorting, recycling, and pretreatment with material and/or energy recovery produces new residues, which finally end up at landfills.
