1. 1. Mapping spontaneous biological phosphorus removal in a membrane bioreactor process without the anaerobic condition : Investigating the effect of alternative external carbon sources

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Ross Roberts; [2020]
   Keywords : enhanced biological phosphorus removal; PAO; anoxic; carbon source; ethanol; ORP;

   Abstract : Phosphorus removal in wastewater treatment is commonly achieved by chemical precipitation, enhanced biological phosphorus removal (EBPR) or a simultaneous combination of the two. A defined anaerobic condition is widely regarded as the critical element to sustain EBPR. However, this study demonstrates that EBPR is indeed occurring in a 4. READ MORE

3. 2. Limiting microplastic pollution from municipal wastewater treatment : A circular economic approach

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Jordy van Osch; [2020]
   Keywords : Microplastics; circular economy; wastewater treatment plant; resource recovery; Multi-criteria analysis;

   Abstract : The increasing amount of microplastics found in the environment have underscored the urgency to identify, develop and deploy scenarios in which municipal wastewater treatment plants (MWWTPs) limit the release of urban microplastics into the environment. Simultaneously, the global trend towards a circular economy has defined the conditions for these scenarios in relation to the water-energy- nutrient nexus. READ MORE

4. 3. Stable increase of organic loading rate in anaerobic membrane bioreactors working at ambient temperature

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Jean Monhonval; [2015]
   Keywords : environmental engineering; anaerobic membrane bioreactor; stability indicators; ambient methanization; stable increase organic loading rate; vattenförsörjningsteknik; avloppsteknik; water engineering; Technology and Engineering;

   Abstract : Anaerobic processes are an interesting alternative to treat wastewaters instead of aerobic treatments as it allows recovery of energy with the produced biogas while removing organic matter. In the industry, lots of low-strength industrial wastewaters are available and unused for biogas production due to their low concentration of organic material and high volumes (slaughterhouse wastewaters, dairies and beverages industries, oils and fats producers).

5. 4. Rapid Bio-methanation of Syngas by High Cell-density in Reverse Membrane Bioreactors

   University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

   Author : Konstantinos Chandolias; [2014]
   Keywords : syngas; fermentation; reverse; membrane; bioreactor; bio-methanation; high cell density;

   Abstract : Syngas fermentation via gasification is a two-stage process, which contains gasification of feedstock into syngas and syngas bio-methanation by anaerobic microorganisms. This project is a study on syngas fermentation. The gasification feedstock can be difficult-to-degrade solid waste so; waste volumes are reduced while green energy is produced. READ MORE
