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. Mapping of spontaneous biological phosphorous removal in MBR-process

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Benjamin Fridh; [2020]
   Keywords : Polyphosphate poly-P ; Phosphorous;

   Abstract : An unexpected biological removal of phosphorous in IVL Hammarby Sjöstadsverket pilot membrane bioreactor (MBR) wastewater treatment process was investigated by three distinct methods. a) Investigation and quantification of the biological phosphorous uptake (bio-P) capacity by phosphate release tests (PRT), b) validation of bio-P occurrence by granular polyphosphate (poly-P) staining and microscopy and c) metagenomic community structure analysis to map the sludge habitat.

4. 3. 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

5. 4. Environmental Impact of Wastewater Treatment - A Study of Membrane Bioreactor and Iso-Disc Technologies from a Life Cycle Perspective

   University essay from Lunds universitet/Miljö- och energisystem

   Author : Isabelle Zilling; Krister Lestander; [2019]
   Keywords : MBR technology; Iso-Disc technology; Life cycle assessment; Wastewater treatment; Conventional activated sludge process; Activated sludge process; Electricity mix; Technology and Engineering;

   Abstract : This study evaluates and compares two different wastewater treatment technologies from a life cycle perspective. The evaluating technologies are Membrane Bioreactor (MBR) technology with a microfiltration membrane and Iso-Disc technology. READ MORE

6. 5. Suitable treatment of source separated greywater for discharge into an Urban Environment

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Evalyne Cathy Arinaitwe; [2018]
   Keywords : water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

   Abstract : It can no longer be refuted that greywater reuse is paramount to curbing the persistent global water crisis. Of the domestic wastewaters, greywater is less polluted than blackwater, but treatment is still necessary to make it safe for reuse. The most common greywater reuse application is toilet flushing.
