1. 1. Post-Denitrification on Sand Filter at Bromma Wastewater Treatment Plant

   University essay from KTH/Kemi

   Author : Emil Blocksjö; [2022]
   Keywords : Sand filter; Post-Denitrification; Nitrate; Nitrification; Wastewater; Sandfilter; Efterdenitrifikation; Nitrat; Nitrifikation; Avloppsvatten;

   Abstract : Examensarbetets syfte var att undersöka möjligheter till denitrifikation på sandfilter (SF) i industriell skala och hur det jämför sig med konventionella metoder för att uppnå denitrifikation och effekten av förändringen på processen vid Bromma reningsverk. Parametrar som undersöktes var rening av ammonium och nitrat, luftning, temperatur, pH, rening av fosfor, rening av organiskt material, rening av suspenderat material, förbigång av vatten vid SF och aktivslamanläggning (ASA), drifttider för SF:arna och total vattenbelastning på ASA och SF.

3. 2. Nitrogen removal in MBBR : Investigating the effect of temperature

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Rediet Tezera Tafese; [2022]
   Keywords : Wastewater; Nitrogen removal; Nitrification; Denitrification; MBBR; Cold temperature; Avloppsvatten; Kväverening; Nitrifikation; Denitrifikation; MBBR; låg temperatur;

   Abstract : The project undertaken in this thesis was performed at MittSverige Vatten och Avfall (MSVA) in cooperation with the Swedish Environmental Research Institute (IVL). The effect of temperature on nitrogen removal using moving bed biofilm reactor (MBBR) was controlled using two separate lines by investigating the influence of temperature on nitrification, pre-denitrification, and post- denitrification in a pilot plant scale.

4. 3. 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

5. 4. Yield of Bromate from Ozonated Wastewater and the Potential for Biological Reduction of Bromate in Wastewater in Sweden

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Lauren Dell; [2020]
   Keywords : biological reduction; bromate; ozonation; disinfection by-products; bromide; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

   Abstract : The impact that anthropogenic micropollutants have on the environment is increasingly gaining attention. As a result of this, Sweden, among other countries, is looking towards implementing advanced treatment for micropollutant and pharmaceutical product removal from wastewater prior to discharge into the environment.

6. 5. Monitoring of denitrifying activities in moving bed biofilm reactors with an ex-situ manometric batch test

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Sofia Bårdskär; [2016]
   Keywords : water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

   Abstract : Emissions of reactive nitrogen to the environment is of major concern, e.g. since it is known to contribute to eutrophication and dead sea floors in water bodies. The capability to remove nitrogen from wastewater has therefore become a critical means of preserving and protecting the environment. READ MORE
