  1. 1. Evaluation of pharmaceutical removal in seven WWTPs : Efficiency of different treatment technologies

    Master-uppsats, Stockholms universitet/Institutionen för miljövetenskap

    Författare :Viktor Munkhammar; [2023]
    Nyckelord :Pharmaceuticals; wastewater treatment plant; removal efficiency; biological treatment; ozonation;

    Sammanfattning : Wastewater treatment plants (WWTPs) are originally not constructed to remove pharmaceuticals from the wastewater. Biological treatment technologies used in many WWTPs today, e.g., activated sludge, MBBR and trickling filters, can, however, remove some pharmaceuticals well. LÄS MER

  3. 2. Reduction of Acrylamide in Reject Water from Sludge Dewatering

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Martina Aspegren; [2023]
    Nyckelord :Water treatment techniques; Ozonation; Moving bed biofilm reactor; Trickling filter; Biological degradation; Lake Mälaren; attenreningstekniker; Ozonering; Biofilmreaktor med rörlig bädd; Biobädd; Biologisk nedbrytning; Mälaren;

    Sammanfattning : Norrvatten produces and delivers drinking water to approximately 700 000 people in the northern part of the Stockholm region in Sweden. In their water treatment plant Görvälnverket, water from Lake Mälaren is purified. During the purification, sludge is produced. To be able to use the sludge as landfilling material, it must be dewatered. LÄS MER

  4. 3. Älgarås avloppsreningsverk- studie och metodisk felsökning av en biobädds BOD-rening

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Amanda Haglind; [2015]
    Nyckelord :Biobädd; biologisk rening; BOD; avloppsrening; metodisk felsökning;

    Sammanfattning : Wastewater contains biodegradable materials, which are often measured as BOD7. Trickling filters are sometimes used as a purification step for BOD-reduction. A trickling filter is a tower, which is filled with a carrier material. Microorganisms grow on the carrier material in the form of a biofilm. LÄS MER

  5. 4. Using a biotrickling filter for degradation of cypermethrin, an insecticide frequently used in Tahuapalca, Bolivia

    Master-uppsats, Kemi; Tekniska högskolan

    Författare :Henric Enstedt; [2013]
    Nyckelord :Biofilter; Trickling filter; Fungus; Cypermethrin; Pesticides; Ninhydrin;

    Sammanfattning : The feasibility of using bench-scale biotrickling filter reactors inoculated with the fungus UBAF004, isolated from soil in Tahuapalca, for treatment of water contaminated with cypermethrin was investigated. Wood chips, gravel and ceramics were tested as packing materials for the reactors in batch experiments in small glass flasks. LÄS MER

  7. 5. Utvärdering av den biologiska reningen av processavloppsvattnet vid GE Healthcare i Uppsala

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaper

    Författare :Malin Fridlund; [2005]
    Nyckelord :Biological wastewater treatment; organic reduction; biological reactor; biofilm process; moving bed carrier; Natrix;

    Sammanfattning : GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity.
