  3. 22. Hydrolysis of waste activated sludge from pulp and paper mills : effect on dewatering properties and biogas potential by utilizing existing side streams

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Louise Hjalmarsson; [2021]
    Keywords : hydrolysis; dewatering properties; biogas; sludge; waste activated sludge;

    Abstract : A big challenge within pulp and paper mills is the large quantities of waste activated sludge (WAS) that is produced during the wastewater treatment. The WAS is made up of biological cells and extra polymeric substances (EPS) and can bind a large amount of water causing difficulties to dewater the WAS. READ MORE

  6. 25. Design and Optimization of Ultrafiltration Membrane Setup for Wastewater Treatment and Reuse

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ekansh Sharma; [2020]
