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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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.

  2. 2. Evaluating the suitability of carbon source from fermentation of primary filter sludge for biological nutrient removal

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Sanna Sahlin; [2021]
    Keywords : Wastewater treatment; batch activity tests; NUR tests; anaerobic P release tests; EBPR; denitrification; removal rates; internal carbon source; fermentate; water and environmental engineering; Technology and Engineering;

    Abstract : Traditional biological nutrient removal (BNR) processes in wastewater treatment require access to easily biodegradable carbon in order to achieve sufficient removal. However, a lot of the carbon in the influent wastewater is not directly available for BNR bacteria but need to undergo hydrolysis first. READ MORE

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

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Rounak Niranjan; [2021]
    Keywords : 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;

    Abstract : 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.

  4. 4. 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

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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE
