  1. 1. 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

  3. 2. Inhibition of Nitrification in Industrial Wastewater - Identification of Sources

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Vidar Aspelin; Jennifer Ekholm; [2017]
    Keywords : nitrite; nitrate; industrial wastewater; inhibition of nitrification; additivity; nitrifikationshämning; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

    Abstract : The discharge of industrial wastewaters (WWs) to wastewater treatment plants (WWTPs) can be problematic due to their sometimes elevated concentrations of toxic compounds compared to municipal wastewater. Also, industrial WWs often contain compounds that are unique to the specific production, and the receiving WWTP is not always designed to remove these compounds. READ MORE

  4. 3. Evaluation of the effect of different SCOD/TN ratios in a mainstream nitritation process

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Doaa el Halabi; [2017]
    Keywords : Partial nitrification; nitritation; microscreen; filtration; Chemical oxygen demand; moving bed biofilm reactor; Partial nitrification anammox; PNA.; Technology and Engineering;

    Abstract : Avloppsvatten är rikt på organiskt material, det organiska materialet har med fördel använts för biogasproduktion. Den traditionella kvävereningsprocessen kräver organiskt material, därför har ett extern organiskt material använts. READ MORE
