  1. 1. En förstudie om näring- och energiåtervinning från källsorterande avloppssystem

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Sebastian Gisle; [2021]
    Nyckelord :hållbarhet; återvinning; resurshantering;

    Sammanfattning : The world's demand for nitrogen and phosphorus is increasing at the same time as high concentrations of the nutrients flow out from water treatment plants. The presence of nitrogen and phosphorus in nature is a contributing factor to eutrophication and thus damages ecosystems. LÄS MER

  3. 2. high loaded anaerobic mesophilic digestion of sewage sludge : An evaluation of the critical organic loading rate and hydraulic retention time for the anaerobic digestion process at Käppala Wastewater Treatment Plant (WWTP).

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Framtidens energi

    Författare :Ibrahima Sylla; [2020]
    Nyckelord :Dewaterability; Mesophilic anaerobic digestion; Methane; Organic load rate; Renewable energy source; Sludge filterability; Wastewater treatment.; Avvattningsförmåga; mesofil anaerob rötning; metan; organisk belastning; förnybar energikälla; slammets filtrerbarhet; vattenrening;

    Sammanfattning : Käppala wastewater treatment plant (WWTP) has, during a few years, observed an increase in organic loading rate (OLR) in the mesophilic anaerobic digester R100, due to an increased load to the WWTP. The digestion of primary sludge at Käppala WWTP is today high loaded, with a high organic loading rate (OLR) and low hydraulic retention time (HRT). LÄS MER

  5. 4. Sustainability assessment of potential wastewater treatment techniques in Tupiza, Bolivia

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Johanna Burström; [2020]
    Nyckelord :MCA; wastewater treatment; sustainable sanitation; Bolivia; stabilisation ponds; anaerobic reactors; constructed wetland; alkaline treatment of sludge; ammonia treatment of sludge; MCA; avloppsrening; hållbara VA-lösningar; Bolivia; stabiliseringsdammar; anaerobiska reaktorer; anlagd våtmark; alkalin slambehandling; slambehandling med ammoniak; Análisis multicriterio; tratamiento de aguas residuales; saneamiento sostenible; Bolivia; estanques de estabilización de desechos; reactores anaeróbicos; humedales artificiales; tratamiento de lodo con cal; tratamiento de lodo con urea;

    Sammanfattning : Aiming for sustainable sanitation systems can provide benefits among a vast range of Sustainable Development Goals. In this study the sustainability of potential options for renovating or upgrading thewastewater treatment plant in Tupiza, a rapidly growing city in theSouthern highlands of Bolivia, was evaluated.

  7. 5. Mainstream Deammonification process monitoring by bacterial activity tests

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

    Författare :Andrea Carranza Muñoz; [2020]
    Nyckelord :Ammonia Oxidizing Bacteria AOB ; Anammox; Bacterial activity; Deammonification; Heterotrophic bacteria; IFAS; Mainstream wastewater; Nitrite Oxidizing Bacteria NOB ; Nitrogen Removal.;

    Sammanfattning : Deammonification is a widely used technology for side stream treatment with rich ammonium streams at relatively high temperatures, such as, the reject water coming from dewatering units in treatment of digested sludge and industrial wastewaters. The deammonification process has lower operational costs than conventional systems, consumes less energy, enables the increase of biogas production and it is easy to implement. LÄS MER
