1. Properties of Activated Sludge Flocs
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.

2. Flocculation with Polyelectrolytes in Latex and Microbial Systems
Abstract : Adsorption of cationic polyelectrolytes onto polystyrene latices was studied as function of polymer chemical composition and molecular weight, polymer and surface charge density and ionic strength. The ratio between polymer charges and surface charges was close to one when distances between polymer and surface charges were equal. READ MORE
