    Uppsats för yrkesexamina på avancerad nivå, Institutionen för informationsteknologi

    Författare :Sandra Abrahamsson; [2013]
    Nyckelord :multivariate analysis; PCA; principal component analysis; PLS; partial least squares projection to latent structures; soft sensor; WWTP; Hammarby Sjöstadsverk; multivariat analys; PCA; principalkomponentanalys; PLS; partial least squares projection to latent structures; mjukvarusensor; avloppsreningsverk; Hammarby Sjöstadsverk;

    Sammanfattning : Varje studie av en verklig process eller ett verkligt system är baserat på mätdata. Förr var den tillgängliga datamängden vid undersökningar ytterst begränsad, men med dagens teknik är mätdata betydligt mer lättillgängligt. LÄS MER

  3. 12. Nitrogen Removal in the Pilot Plant ITEST (Increased Technology in Sewage Treatment).

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Stefania Caglia; [2013]
    Nyckelord :Nitrogen removal; Temperature effect; Wastewater treatment;

    Sammanfattning : Regions with a cold winter, as in the Baltic countries, have a problem to meet the nitrogen requirement in the Urban Wastewater Treatment Directive 98/15/EC. Especially in the winter season, the temperature of the influent wastewater could arrive also below 10°C and this delays the biological processes that takes place in the wastewater treatment.

  4. 13. Removal and Recycling of Phosphorus from Wastewater Using Reactive Filter Material Polonite®

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemivetenskap (CHE)

    Författare :Anna Österberg; [2012]
    Nyckelord :Phosphorus; Polonite®; adsorption; filter; removal; recycling; recovery; wastewater treatment;

    Sammanfattning : Literature reviews and laboratory work were used to examine the phosphorus removal efficiency of the reactive filter material Polonite®. This material is produced from the calcium carbonate and silica based rock Opoka. LÄS MER

  5. 14. Use of Manganese Compounds and Microbial Fuel Cells in Wastewater Treatment.

    Master-uppsats, KTH/VA-teknik, Vatten, Avlopp och Avfall

    Författare :Junli Jiang; [2011]
    Nyckelord :Digested Sludge; Manganese Compounds; Microbial Fuel Cell; Potassium Permanganate;

    Sammanfattning : Manganese compounds have a high potential for treating wastewater, both for utilizing its oxidation, flocculation ability and catalyst ability in anaerobic nitrification. The promising use of manganese compounds (such as permanganate and manganese dioxide) is regarded as an effective method of treating organic compounds in wastewater from municipal and industrial wastewater.

  7. 15. Effect of Temperature on Biogas Production in Anaerobic Treatment of Domestic Wastewater UASB System in Hammarby Sjöstadsverk.

    Master-uppsats, KTH/VA-teknik, Vatten, Avlopp och Avfall

    Författare :Chengyuan Zhao; [2011]
    Nyckelord :Anaerobic wastewater treatment; UASB reactor; Domestic wastewater; Temperature; COD; Biogas production; OLR;

    Sammanfattning : The upflow anaerobic sludge blanket (UASB) reactor is widely used around the world to treat variety of domestic andindustrial wastewater with three main advantages: production of biogas as renewable energy, no need of support structure for development of microorganisms and high rate treatment efficiency with low rate of biomass production. This study evaluates the effect of temperature on biogas production and CODtotal removal in Line 4-UASB system treating domestic wastewater in Hammarby Sjöstadsverk. LÄS MER
