1. Experimental Study of Flow Fields in Moving Bed Biofilm Reactors
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : 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. LÄS MER
2. Effect of biofilm thickness and carrier type on the performance of anaerobic moving bed biofilm reactors (AnMBBRs)
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The anaerobic moving bed biofilm reactor (AnMBBR) is a wastewater treatment process that has shown effective for the treatment of industrial wastewaters. As the AnMBBR is a biofilm process, nutrients, products, etc. must be transported through the biofilm. The thickness of the biofilm may, therefore, impact the process. LÄS MER
3. Considerations for the Establishment of an Anaerobic Biofilm in an AnMBBR
Master-uppsats, Lunds universitet/Teknisk mikrobiologiSammanfattning : Behandling av avloppsvatten för att avlägsna ämnen som kan ha en negativ påverkan på den mänskliga hälsan och naturen är mycket viktigt innan vattnet återanvänds eller släpps ut i naturen. Intresset för anaerob vattenrening har ökat eftersom det är ett bra komplement till aeroba processer, samt för att det producerar energi i form av metangas. LÄS MER
4. Utvärdering av den biologiska reningen av processavloppsvattnet vid GE Healthcare i Uppsala
Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaperSammanfattning : GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity.
