1. 1. Evaluation of pharmaceutical removal in seven WWTPs : Efficiency of different treatment technologies

   University essay from Stockholms universitet/Institutionen för miljövetenskap

   Author : Viktor Munkhammar; [2023]
   Keywords : Pharmaceuticals; wastewater treatment plant; removal efficiency; biological treatment; ozonation;

   Abstract : Wastewater treatment plants (WWTPs) are originally not constructed to remove pharmaceuticals from the wastewater. Biological treatment technologies used in many WWTPs today, e.g., activated sludge, MBBR and trickling filters, can, however, remove some pharmaceuticals well. READ MORE

3. 2. 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

4. 3. Improving the BBR congestion control algorithm for QUIC

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Alexander Chouchliapin; [2023]
   Keywords : congestion control; bbr; quic; algorithm;

   Abstract : Congestion control is an important aspect of network technology, where traffic load is balanced to not cause an overflow in the system. Google has proposed its own protocol, QUIC, which is described as being set to supersede the TCP protocol. READ MORE

5. 4. 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

6. 5. 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
