  1. 6. Experimental Study of Flow Fields in Moving Bed Biofilm Reactors

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Shea Nee Chew; [2023]
    Keywords : Moving bed biofilm reactors; Biofilm carriers; Mechanical mixing; Mixer configurations; Carrier mixing; Biofilmsreaktorer med rörlig bädd; Biofilmsbärare; Mekanisk blandning; Blandarkonfigurationer; Bärarblandning;

    Abstract : With the rise in global energy prices, as well as energy consumption being the largest source of greenhouse gas emissions, biofilm-based systems utilized for wastewater treatment, such as moving bed biofilm reactors (MBBRs), have grown in popularity for their lower energy consumption compared to conventional activated sludge processes. However, this technology requires large amounts of energy to constantly distribute and suspend its biofilm carrier within the reactor by either aerators or mechanical mixers. READ MORE

  3. 7. Production of succinic acid by Actinobacillus succinogenes in attached-growth bioreactors and dynamic modelling of biofilm formation

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Henrik Östberg; [2023]
    Keywords : Actinobacillus succinogenes; Succinic acid; Biofilm; Attached-growth bioreactor; Dynamic modelling; Cell cultivation; Applied microbiology; Biology and Life Sciences;

    Abstract : Actinobacillus succinogenes is a microorganism is a very efficient producer of succinic acid, a chemical with a wide range of industrial applications. The bacterium is prone to form biofilm, a flocculation of cells attached to a surface. READ MORE

  4. 8. Numerical simulations of solute transport in microchannels impregnated with a biofilm

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Tim Berglund; [2023]
    Keywords : Biofilms; Numerical simulation; Solute transport;

    Abstract : The feasibility of simulating solute transport in a channel impregnated witha biofilm is investigated. Biofilm factors relevant for numerical simulation arestudied to determine a suitable range of simulation. READ MORE

  5. 9. Rening och rekreation : ett gestaltningsförslag för en dagvattendamm i Tallstråket med flytande våtmarker

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Elvira Jubel; [2023]
    Keywords : Dagvattendamm; rekreation; flytande våtmarker; Tallstråket; dagvattenhantering; rening; metaller; föroreningar; gestaltning;

    Abstract : Med ett förändrat klimat och städer som förtätas och hårdgörs ställs högre krav på dagvattenhantering. I städer som förtätas prioriteras även blå- och grönytor ofta bort, och invånarnas möjligheter till rekreation minskar. READ MORE

  6. 10. Reduction of Acrylamide in Reject Water from Sludge Dewatering

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Martina Aspegren; [2023]
    Keywords : Water treatment techniques; Ozonation; Moving bed biofilm reactor; Trickling filter; Biological degradation; Lake Mälaren; attenreningstekniker; Ozonering; Biofilmreaktor med rörlig bädd; Biobädd; Biologisk nedbrytning; Mälaren;

    Abstract : Norrvatten produces and delivers drinking water to approximately 700 000 people in the northern part of the Stockholm region in Sweden. In their water treatment plant Görvälnverket, water from Lake Mälaren is purified. During the purification, sludge is produced. To be able to use the sludge as landfilling material, it must be dewatered. READ MORE
