  1. 21. Properties of Activated Sludge Flocs

    Författare :Britt-Marie Wilen; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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.

  3. 22. Metal release from stainless steel and CoCrMo alloys in protein-rich environments – effects of protein aggregation, friction, and irradiation

    Författare :Zheng Wei; Yolanda Hedberg; Inger Odnevall Wallinder; Daniel Klint; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal release; stainless steel; CoCrMo; protein aggregation; friction; irradiation; Vroman effect; Kemi; Chemistry;

    Sammanfattning : Highly corrosion-resistant alloys are used in sensitive environments such as the human body and food environments. However, even tiny amounts of released metals from these surfaces could potentially cause adverse effects. It is hence important to study the biointerface between corrosion-resistant alloys and protein-rich environments. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein adsorption; protein arrays; lipid bilayer; SPR; scFv; lipid vesicle; DNA arrays; QCM-D;

    Sammanfattning : Biomolecular sensing often includes immobilization of biomolecules, e.g. DNA, antibodies etc., to solid supports, where they act as selective recognition elements. LÄS MER

  7. 25. Heat and Mass Transfer Investigations of Relevance for Food Engineering Applications

    Författare :Dirk Sterner; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; mathematical modelling; frozen and non-frozen food; minced beef patties; cooking; heat and mass transfer; plate heat exchangers; evaporation;

    Sammanfattning : This thesis concerns two interrelated subjects of heat and mass transfer processes. The first one concerns mainly experimental measurements, with a subsequent development of a calculation procedure, of the thermal and hydraulic performances, experimental methods and evaluation procedures applied on various plate heat exchangers (PHEs) as evaporators with the refrigerant ammonia as working medium.
