1. 1. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Mehrzad Ghassemi; [2022]
   Nyckelord :Greywater; EBPR; Phosphorus; Biological treatment; Water and environmental engineering; Technology and Engineering;

   Sammanfattning : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes.

3. 2. Opportunities for increased nutrient recovery at centralised wastewater treatment plants through urine separation

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Hanna Gustavsson; [2021]
   Nyckelord :Nutrient recovery; urine separation; magnesium ammonium phospahte; MAP; ammonium sulphate; AMS; and DHI s WEST;

   Sammanfattning : Municipal wastewater contains a significant amount of nutrients such as phosphorus (P) and nitrogen (N). Therefore have the interest of recovering these nutrients at wastewater treatment plants (WWTP) increased. Nutrient recovery would generate revenue for the WWTP, as it is possible to sell the products as fertiliser. LÄS MER

4. 3. Identifying factors that correlate with Enhanced Biological Phosphorus Removal upsets at Lundåkraverket

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Rounak Niranjan; [2021]
   Nyckelord :Enhanced biological phosphorus removal; polyphosphate accumulating organisms; glycogen accumulating organisms; sludge content in aeration basin; nitrates in aeration basin; pH of incoming water; principal component analysis; pairwise correlations; inhibition factors;

   Sammanfattning : The Enhanced Biological Phosphorus Removal (EBPR) process is characterized as the most sustainable process to remove phosphorus from wastewater albeit with high variability in performance efficiency. Thus, unpredictable upsets in the EBPR system is the norm across several wastewater treatment plants throughout Sweden, forcing the hand of the operators to dose higher volume of chemicals to reach the effluent requirements.

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

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

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

   Sammanfattning : 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. LÄS MER

7. 5. Investigation of Readily Degradable Carbon Source Production by Hydrolyzing Sludge and Reject water at Ängen planned WWTP

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Kartika Novitasari Pranoto; [2020]
   Nyckelord :EBPR; activated sludge; primary sludge; reject water; hydrolysis rate; hydrolysis yield; VFAs; pH; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

   Sammanfattning : As form of effort to mitigate the increase of pollution level that caused by human activity, Ängen wastewater treatment plant (WWTP) will be built in Lidköping as part of the European LIFE project (LIWE LIFE). Ängen WWTP will be operated based on enhanced biological phosphorus removal (EBPR) technology. LÄS MER
