  1. 1. Energy recovery through anaerobic co-digestion of food waste and wastewater treatment sludge : A proposition of a water treatment and biogas plant for a floating island in Stockholm.

    Master-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Författare :Rodrigo Bahena; [2022]
    Nyckelord :;

    Sammanfattning : The urge for more sustainable living motivated the Stockholm Tiny House Expo. The project aims to build a floating, sustainable, man-made island for living and working outside of Stockholm. This paper proposes a waste management method with possible energy recovery for the island. LÄS MER

  3. 2. Reduktion av föroreningar i processvatten från en äggfabrik i Brasilien : Kväve- och fosforrening i anlagda våtmarker.

    Kandidat-uppsats, Högskolan i Halmstad/Sektionen för ekonomi och teknik (SET)

    Författare :Alexandra Charlson; [2014]
    Nyckelord :Constructed treatment wetland; nitrogen removal; phosphorus removal; industrial food wastewater; water purification; Anlagd våtmark; kväverening; fosforrening; processvatten från livsmedelsindustrier; vattenrening;

    Sammanfattning : A water treatment unit consisting of two aeration basins, two settling tanks, a residence basinand a horizontal subsurface flow wetland were used to treat wastewater from an eggprocessing factory in Brazil. The aim of this paper was to determine the efficiency of thesystem in reducing nitrogen, phosphorus, BOD5 and TSS (among other parameters) andgetting a further understanding on different kinds of constructed treatment wetlands as well astheir nitrogen and phosphorus removal processes.

  4. 3. Pathogen and indicator organisms removal in artificial greywater subjected to aerobic treatment : comparison of four filter media

    Master-uppsats, SLU/Dept. of Energy and Technology

    Författare :Ramiyeh Molaei; [2014]
    Nyckelord :Activated carbon; pine bark; biochar; BOD5 reduction; Enterococcous faecalis; greywater reuse; bacteriophage MS2; bacteriophage фX174; Salmonella spp;

    Sammanfattning : Treated greywater has a good potential to be used as a source of water. This study analyzes the removal of Salmonella spp., Enterococcous faecalis, bacteriophage ɸX174 and bacteriophage MS2 from greywater by filtration through biochar, bark, activated carbon and mixture of bark and activated carbon.

  5. 4. Bottensubstrat och dess inverkan på reducering av BOD5, COD och TKN i lakvatten genom konstruerade rotzonsanläggningar : En pilotstudie vid Univates, Lajeado – RS Brasilien

    Kandidat-uppsats, Ekologi och miljövetenskap

    Författare :Emy Ekholm; [2010]
    Nyckelord :Leachate water; sub surface flow wetlands; substrate grain size; reduction; BOD; COD; nitrate.;

    Sammanfattning : Treatment wetlands been showed efficient for reducing pollutant in waste water. In Lajeado – RS, Brazil the landfill has poor leachate water treatment. It is necessary to supplement the treatment plant because they need to reduce BOD, COD and nitrate of the water going to recipient. A subsurface flow wetland (SSF) can be a good choice. LÄS MER

  7. 5. A Feasibility Study on Sustainable Wastewater Treatment Using Constructed Wetlands - An Example from Cochabamba, Bolivia

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Helena Cordesius; Sofia Hedstrom; [2009]
    Nyckelord :minor field study; water treatment; Cochabamba; constructed wetlands; sewage water; horizontal subsurface flow; Bolivia; reuse of wastewater; wastewater; Technology and Engineering;

    Sammanfattning : Cochabamba in Bolivia is an example of a city that faces increasing environmental problems and health risks due to insufficient sewage system coverage and municipal wastewater treatment. The situation is especially severe in peri-urban fast growing settlements. LÄS MER
