1. 1. Treatment and using of greywater in sorting wastewater system as a resource

   University essay from KTH/Kemiteknik

   Author : Maza Seyuom Seifu; [2022]
   Keywords : Greywater; heat recovery; physical treatment; chemical treatment; biological treatment; Gråvatten; värmeåtervinning; fysikalisk behandling; kemisk behandling; biologisk behandling;

   Abstract : Det här projektet redogör för olika behandlingstekniker för gråvatten och för tillämpningar för olika ändamål inom återanvändning. Syftet är att föreslå en lämplig processdesign för behandling av gråvatten i stadsmiljö, på Loudden, Norra Djurgårdsstaden (NDS). READ MORE

3. 2. Mapping spontaneous biological phosphorus removal in a membrane bioreactor process without the anaerobic condition : Investigating the effect of alternative external carbon sources

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Ross Roberts; [2020]
   Keywords : enhanced biological phosphorus removal; PAO; anoxic; carbon source; ethanol; ORP;

   Abstract : Phosphorus removal in wastewater treatment is commonly achieved by chemical precipitation, enhanced biological phosphorus removal (EBPR) or a simultaneous combination of the two. A defined anaerobic condition is widely regarded as the critical element to sustain EBPR. However, this study demonstrates that EBPR is indeed occurring in a 4. READ MORE

4. 3. Mapping of spontaneous biological phosphorous removal in MBR-process

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Benjamin Fridh; [2020]
   Keywords : Polyphosphate poly-P ; Phosphorous;

   Abstract : An unexpected biological removal of phosphorous in IVL Hammarby Sjöstadsverket pilot membrane bioreactor (MBR) wastewater treatment process was investigated by three distinct methods. a) Investigation and quantification of the biological phosphorous uptake (bio-P) capacity by phosphate release tests (PRT), b) validation of bio-P occurrence by granular polyphosphate (poly-P) staining and microscopy and c) metagenomic community structure analysis to map the sludge habitat.

5. 4. Limiting microplastic pollution from municipal wastewater treatment : A circular economic approach

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Jordy van Osch; [2020]
   Keywords : Microplastics; circular economy; wastewater treatment plant; resource recovery; Multi-criteria analysis;

   Abstract : The increasing amount of microplastics found in the environment have underscored the urgency to identify, develop and deploy scenarios in which municipal wastewater treatment plants (MWWTPs) limit the release of urban microplastics into the environment. Simultaneously, the global trend towards a circular economy has defined the conditions for these scenarios in relation to the water-energy- nutrient nexus. READ MORE

6. 5. Intensification of lignocellulosic bioethanol production process using multi-staged membrane bioreactors

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Clarisse Uwinez; [2019]
   Keywords : Interconnected continuous hydrolysis and fermentation; lignocellulosic bioethanol; Membrane bioreactors; process intensification; lignin recovery; membrane fouling.;

   Abstract : The exploitation of lignocellulosic materials with the aim of producing high value-added products will potentially counteract concerns related to the depletion of fossil resources or exponential population growth. Bioethanol produced from lignocellulosic agriculture residue exhibits promising alternative to the petroleum-based fossil fuel which reduces net emission of greenhouse gases (GHG). READ MORE
