   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; floc strength; aerobic microbial activity; reflocculation; dissolved oxygen concentration; settling; deflocculation; filamentous microorganisms; shear forces; floc size; activated sludge;

   Abstract : The quality of the effluent from activated sludge treatment plants is highly dependent on the efficiency of the solid-liquid separation process. The aim of this thesis was to study (i) the effects of dissolved oxygen (DO) concentration on effluent turbidity and flocculation, as well as on the settling properties of activated sludge, for both short term and long term scales, and (ii) the influence of aerobic microbial activity on the stability of activated sludge flocs.

   Abstract : Kraft pulping technology is currently the most commonly-used method for producing paper pulp from wood. A new and promising opportunity for Kraft pulp mills is to take a step towards becoming biorefineries by implementing technologies able to extract and convert the organic by-products, such as lignin, into a wide range of value-added products and chemicals.
