1. 1. 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. 2. 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

4. 3. Pilot scale partial denitratation coupled anammox: an evaluation

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Tobias Ellingsen; [2022]
   Keywords : mainstream anammox; partial denitratation anammox; partial denitrification anammox; PDA; nitrite inhibition; anammox; water and environmental engineering; Technology and Engineering;

   Abstract : På avloppsreningsverk (ARV) som tillämpar kväverening är den vanligaste tekniken nitrifikation följt av denitrifikation. Denna process kräver omfattande luftning, vilket både är elintensivt och minskar mängden biogas som kan utvinnas. READ MORE

5. 4. Potential of waste-derived VFAs-bearing effluents as an external carbon source for MBBR denitrification of domestic wastewater

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

   Author : Seyed Reza Manafi Khosroshahi; [2022]
   Keywords : Volatile fatty acids; Denitrification; Wastewater treatment; Biological nutrient removal; Nitrate removal; Electron accepter; Carbon source; Electron doner; Moving bed biofilm reactor; Nanofiltration; VFA concentration; Discharge standards; Carriers; acclimatization; VFAs; MMBR; NF; WWTP; BNR;

   Abstract : In conventional wastewater treatment plants, methanol, ethanol, and acetate are used as carbon source for the denitrification process in the biological nutrient removal. However, growing concern regarding economical costs and carbon footprints from the fossil-based production of these chemicals have forced the companies to look for other alternatives. READ MORE

6. 5. PFAS in a Swedish wastewater treatment plant : An analysis of the effectiveness of major treatment steps on 33 PFAS

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Jonatan Forsberg; [2022]
   Keywords : Northern Sweden; PFAS; municipal WWTP; MBBR; GAC;

   Abstract : Wastewater treatment plants (WWTP) are known spreaders of per- and polyfluoroalkyl substances (PFAS) into the environment. Luleå University of Technology is conducting a yearlong study in which PFAS concentrations in the different treatment steps are measured at Uddebo treatment plant. READ MORE
