  1. 1. Effects of recirculating water treatment sludge

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Sofia Mile; [2023]
    Keywords : Chemical Engineering; Water and Environmental Engineering; Water Treatment; Coagulation Flocculation; Sludge Recirculation; Technology and Engineering;

    Abstract : Drinking water is crucial in our everyday life. As with many other processes, it is important to produce water of drinking quality in a sustainable manner. This can occur by e.g. READ MORE

  3. 2. Modelling the full-scale N2O emissions from wastewater treatment plants for identifying mitigation strategies

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Naga Deepika Peddamudium; [2023]
    Keywords : Modelling; simulation; ASM2dISS; N2O production pathways; N2O emission factor; mitigation strategies; water and environmental engineering; Technology and Engineering;

    Abstract : Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. READ MORE

  4. 3. Recovery of Phosphorus from Incineration of Sewage Sludge

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Aditi Bhasin; [2017]
    Keywords : ;

    Abstract : The primary source of phosphorus, phosphate rock, is a non-renewable resource which is expected to get exhausted in the next 50 – 100 years. Sewage sludge in Sweden constitutes 25% of the annual phosphorus in the country, making it a potentially significant source for phosphorus recovery. READ MORE

  5. 4. Recirculation of phosphorus : an optimization analysis of processes to recycle phosphorus from sewage sludge

    University essay from SLU/Dept. of Economics

    Author : Linnéa Sellberg; [2016]
    Keywords : cost minimisation; fertilizer; phosphorus; recycling; recirculation; sewage sludge; wastewater treatment;

    Abstract : Phosphorus is a limited resource and for countries like Sweden without domestic mines, it becomes increasingly important to recycle this resource. Sewage sludge is rich in phosphorus and has traditionally been used as a fertiliser via direct application to farmland. READ MORE

  6. 5. Enhanced biogas production by increasing organic load rate in mesophilic anaerobic digestion with sludge recirculation.

    University essay from KTH/VA-teknik, Vatten, Avlopp och Avfall

    Author : Zhanzhao Huang; [2012]
    Keywords : biogas; methane; anaerobic digestion; mesophilic condition; organic load rate; specific gas production; total solid and volatile solid;

    Abstract : For enhancing anaerobic sludge digestion and biogas recovery, an increase in organic load rate (OLR) from 1.0 to 3.0kgVS/(m3·day) was imposed upon a new anaerobic digestion process combined with a sludge recirculation. READ MORE
