1. 6. Evaluation of Partial Nitritation/Anammox processes operated in IFAS mode

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Aleksandra Zdyrska; [2017]
   Keywords : ;

   Abstract : The main aim of the study was to optimize Partial Nitritation/Anammox process operated in pilot-scale integrated fixed film activated sludge (IFAS) mode supplied with low-temperature mainstream wastewater and efficiency evaluation based on laboratory analysis and data from online sensors. Main tasks of research work were to stabilize the ongoing process and find the optimal conditions for maximizing effects of nitrogen removal. READ MORE

3. 7. Deammonification efficiency in combined UASB and IFAS system for mainstream WWT

   University essay from KTH/Mark- och vattenteknik

   Author : Noureddine Khayi; [2017]
   Keywords : Ammonium; Nitrite; Nitrate; Deammonification; UASB; MBBR; DO; Aeration; monitoring; on-line control;

   Abstract : The study is about Nitrogen removal from the low concentrated mainstream wastewater after Upflow Anaerobic Sludge Blanket reactor process (UASB) by single-stage Partial Nitritation/Anammox process in a pilot scale reactor at Hammarby Sjöstad in Stockholm. A mixture of various concentrations of dissolved oxygen and different aeration methods have been tested in the pilot scale reactor in five months divided into five periods where the temperature was set at 15° C throughout the study.

4. 8. Evaluation of the effect of different SCOD/TN ratios in a mainstream nitritation process

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Doaa el Halabi; [2017]
   Keywords : Partial nitrification; nitritation; microscreen; filtration; Chemical oxygen demand; moving bed biofilm reactor; Partial nitrification anammox; PNA.; Technology and Engineering;

   Abstract : Avloppsvatten är rikt på organiskt material, det organiska materialet har med fördel använts för biogasproduktion. Den traditionella kvävereningsprocessen kräver organiskt material, därför har ett extern organiskt material använts. READ MORE

5. 9. Evaluation of nitrite oxidizing bacteria (NOB) activity in the nitritation reactor of a two-stage partial nitritation-anammox (PNA) system operating at mainstream conditions

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Emine Gülce Hepdarcan; [2016]
   Keywords : MBBR; Nitrogen removal; Partial Nitritation-Anammox; Wastewater treatment; Z-200 carriers; AOB; NOB; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering; Earth and Environmental Sciences;

   Abstract : Nitrification-denitrification process, which is the most commonly used method for nitrogen removal from wastewaters, is energy demanding and contributes very much to the the carbon footprint of wastewater treatment. One of the alternative methods for nitrogen removal is the nitritation-anammox process. READ MORE

6. 10. High-Loaded Activated Sludge - Improvement of a Solids Retention Time Controlled System

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Per Nobel; [2015]
   Keywords : avloppsteknik water engineering; environmental engineering; vattenförsörjningsteknik; High-loaded activated sludge; Solids retention time control; Sludge foaming; Activated Sludge Model; Non-settleable solids; Technology and Engineering;

   Abstract : Although 100 years old, the activated sludge system remains inevitable for modern wastewater treatment. Advancements within the development of mainstream nitrogen removal techniques based on anaerobic ammonium-oxidising bacteria have renewed the interest in traditional, high-loaded activated sludge systems for COD removal only.
