  1. 1. 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

  3. 2. Comparison of anaerobic sludge granules from different wastewater plants with respect to granule size, substrate degradation and methanogenic community

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Jonathan Andrén; [2018]
    Nyckelord :anaerobic digestion; granule; UASB; EGSB; VFA; methanogen; acetoclastic; hydrogenotrophic; acetogenic; mcrA; ; T-RFLP; methanosarcina; methanosaeta;

    Sammanfattning : Within the objective to replace fossil fuel with sustainable sources there is a growing pressure to advance such development. Anaerobic digestion (AD) is beneficial not only as a waste management technology, but also to recycle organic waste into methane which can be used for heating, production of electricity or vehicle fuel.

  4. 3. Nitrogen removal from municipal wastewater by mainstream Partial Nitritation/Anammox process

    Master-uppsats, KTH/Vatten- och miljöteknik

    Författare :Alessio Robiglio; [2018]
    Nyckelord :Mainstream; Deammonification; IFAS; UASB; Anammox; Anoxia; Aeration; Online; Monitoring; Inhibition; Wastewater;

    Sammanfattning : Mainstream Partial Nitritation/Anammox, also known as Mainstream Deammonification, is a promising technology for future wastewater purification that aims to remove nitrogen from wastewater in order to prevent the eutrophication. It is less costly than the traditional nitrification/denitrification process and it heads towards the direction of converting the WWTPs from energy consuming into energy producing facilities.

  5. 4. Deammonification efficiency in combined UASB and IFAS system for mainstream WWT

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Noureddine Khayi; [2017]
    Nyckelord :Ammonium; Nitrite; Nitrate; Deammonification; UASB; MBBR; DO; Aeration; monitoring; on-line control;

    Sammanfattning : The study is about Nitrogen removal from the low concentrated mainstream wastewater after Upflow Anaerobic Sludge Blanket reactor process (UASB) by single-stage Partial Nitritation/Anammox process in a pilot scale reactor at Hammarby Sjöstad in Stockholm. A mixture of various concentrations of dissolved oxygen and different aeration methods have been tested in the pilot scale reactor in five months divided into five periods where the temperature was set at 15° C throughout the study.

  7. 5. Framtidens substrat? : En tvåstegsprocess för rötning av alger och vass i pilotskala

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Författare :Lars-Ola Ohlsson; Sebastian Karlsson; [2017]
    Nyckelord :Biogas; Biogasprocess; Seafarm; Anaerobisk Nedbrytning; Laminaria Digitata; Phragmites Australis; UASB; Tvåstegsprocess  ;

    Sammanfattning : Detta arbete är en delstudie i projektet Seafarm. Syftet med denna studie är att utreda om algen Laminaria Digitata och vassen Phragmites Australis är lämpliga substrat i en samrötningsprocess för biogasproduktion. LÄS MER
