  1. 1. Analysis and modelling of ozone pre-treatment of sludge for biogas production

    Master-uppsats, KTH/Kemiteknik

    Författare :Gokul Prasad; [2022]
    Nyckelord :Wastewater treatment; anaerobic digestion; sludge pre-treatment; ozonation; methane; Avloppsvattenrening; anaerob rötning; slamförbehandling; ozonering; metan;

    Sammanfattning : Ozonförbehandling av avloppsvattenslam har diskuterats i litteraturen som en potentiell metod för att öka biogasproduktionen och minska slamvolymen. I detta arbete utvecklades en numerisk modell för att simulera effekten av ozonförbehandling på biogasproduktion genom anaerobrötning. Modellen bygger på en befintlig modell från litteraturen.

  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. Analysis of the methanogenic and acetogenic community structure in young calves

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Paulina Lenngren Hysing; [2016]
    Nyckelord :methanogen; acetogen; calves;

    Sammanfattning : The newborn calf that has not been fed colostrum lacks immune defense and ruminal microorganisms needed for digestion of polysaccharides from plants and cellulose. Establishment of a gastrointestinal microbiota is vital. This study aimed to shed light on the establishment of the methanogenic and acetogenic community in young calves. LÄS MER
