    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Ashley Hall; [2022]
    Keywords : water; wastewater; source separation; greywater; phosphorous; precipitation; utfällning; Chemical Engineering; Technology and Engineering;

    Abstract : As our understanding of the impact humans have on the environment changes, so too do the mitigation strategies we employ to prevent it. One major source of anthropogenic pollution is wastewater effluent. READ MORE

  2. 2. Carbon Filters for Drinking Water Treatment – How Flow Rate and Empty Bed Contact Time Influence the Performance

    University essay from KTH/Kemiteknik

    Author : Wilma Bäckström Nilsson; [2021]
    Keywords : Carbon filter; GAC; BAC; Biofilm; Flow rate; NOM; EBCT; Kolfilter; GAC; PAC; biofilm; flödeshastighet; NOM; uppehållstid;

    Abstract : Dricksvatten är en essentiell del av ett hållbart samhälle. Därför är det viktigt att säkerställa säkert dricksvatten genom fungerande vattenreningsverk. En viktig förorening att behandla är NOM, som i sig är ofarligt men som kan producera farliga föroreningar. En teknik som används för behandling av NOM är kolfiltrering. READ MORE

  3. 3. Phosphorus and Nitrogen Removalin Modified Biochar Filters

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Ylva Stenström; [2017]
    Keywords : biochar; modified biochar; phosphorus filter; wastewater; batch adsorption experiment; nitrogen filter; COD; Tot-P; Tot-N; biokol; impregnerat biokol; fosforfilter; avloppsvatten; skakexperiment; kvävefilter; COD; Tot-P; Tot-N;

    Abstract : Onsite wastewater treatment systems in Sweden are getting old and many of them lack sufficient phosphorus, nitrogen and organic carbon reduction. Biochar is a material that has been suggested as an alternative to the common sand or soil used in onsite wastewater treatment systems. READ MORE

  4. 4. Inhibition of Nitrification in Industrial Wastewater - Identification of Sources

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Vidar Aspelin; Jennifer Ekholm; [2017]
    Keywords : nitrite; nitrate; industrial wastewater; inhibition of nitrification; additivity; nitrifikationshämning; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

    Abstract : The discharge of industrial wastewaters (WWs) to wastewater treatment plants (WWTPs) can be problematic due to their sometimes elevated concentrations of toxic compounds compared to municipal wastewater. Also, industrial WWs often contain compounds that are unique to the specific production, and the receiving WWTP is not always designed to remove these compounds. READ MORE

  5. 5. Validation of mercury free methods for analysis of Chemical Oxygen Demand in municipial wastewater

    University essay from Uppsala universitet/Analytisk kemi

    Author : Sandra Jonsson; [2015]
    Keywords : Chemical oxygen demand; COD; Mercury free COD; Pre-commercial innovation procurement; dichromate; wastewater; comparison validation; Kemisk syreförbrukning; COD; Kvicksilverfri COD; för-kommersiell innovations upphandling; dikromat; avloppsvatten; jämförelse validering;

    Abstract : Water is used every day in society and to be able to recycle this water we depend upon efficient wastewater treatment. It is vital to test the wastewater based on different parameters. One parameter is the Chemical Oxygen Demand (COD), which defines the amount of organic substances that can be chemically oxidized within the water. READ MORE
