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. Mainstream Deammonification process monitoring by bacterial activity tests

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Andrea Carranza Muñoz; [2020]
   Keywords : Ammonia Oxidizing Bacteria AOB ; Anammox; Bacterial activity; Deammonification; Heterotrophic bacteria; IFAS; Mainstream wastewater; Nitrite Oxidizing Bacteria NOB ; Nitrogen Removal.;

   Abstract : 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. READ MORE

4. 3. Environmental Impact of Wastewater Treatment - A Study of Membrane Bioreactor and Iso-Disc Technologies from a Life Cycle Perspective

   University essay from Lunds universitet/Miljö- och energisystem

   Author : Isabelle Zilling; Krister Lestander; [2019]
   Keywords : MBR technology; Iso-Disc technology; Life cycle assessment; Wastewater treatment; Conventional activated sludge process; Activated sludge process; Electricity mix; Technology and Engineering;

   Abstract : This study evaluates and compares two different wastewater treatment technologies from a life cycle perspective. The evaluating technologies are Membrane Bioreactor (MBR) technology with a microfiltration membrane and Iso-Disc technology. READ MORE

5. 4. Improvement of Biological Processes of Inland Municipal Wastewater Treatment Plant.

   University essay from KTH/Mark- och vattenteknik

   Author : Wen Li; [2016]
   Keywords : Municipal wastewater treatment; Activated sludge treatment; Intermittent aeration;

   Abstract : This master thesis gives an account for various aeration schemes that are utilized in conventional activated sludge treatment process in a wastewater treatment plant. By altering between different aeration schemes, the project aimed at reducing energy consumption along with maintaining the treatment performance at the plant. READ MORE

6. 5. Evaluation of the suppressive effect of intermittent aeration on nitrite-oxidising bacteria in a mainstream nitritation-anammox process

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Amanda Okhravi; [2015]
   Keywords : Activity tests; anammox; AOB; Manammox; nitritation; NOB; OUR.; Aktivitetstester; anammox; AOB; Manammox; nitritation; NOB; OUR.;

   Abstract : An alternative to conventional removal of nitrogen through autotrophic nitrification and heterotrophic denitrification is autotrophic nitritation-anammox. The anammox bacteria oxidise ammonium directly to nitrogen gas with nitrite as an electron acceptor. READ MORE
