  2. 1. Modelling Aspects of Wastewater Treatment Processes

    Author : Ulf Jeppsson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; control engineering; robotics; Automation; thickening; solids flux; simulation; secondary clarifier; protozoa; predators; parameter estimation; model reduction; model identifiability; mathematical modelling; clarification; biofilm; activated sludge; robotteknik; reglerteknik;

    Abstract : Wastewater treatment processes are inherently dynamic because of the large variations in the influent wastewater flow rate, concentration and composition. Moreover, these variations are to a large extent not possible to control. READ MORE

  4. 2. Adhesion-related interactions of Actinomyces and Streptococcus biofilm bacteria

    Author : Mirva Drobni; Nicklas Strömberg; Karl-Eric Magnusson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biofilm; Actinomyces; Streptococcus; adhesion; Cariology; Cariologi;

    Abstract : Adhesion of bacteria is a key event in biofilm formation and is mediated by bacterial adhesins recognising host or bacterial partner receptors. In oral biofilm formation, primary Actinomyces and Streptococcus colonizers adhere to salivary pellicle proteins such as proline-rich proteins (PRPs) as well as to mucosal surfaces. READ MORE

  5. 3. Antivirulent and antibiofilm salicylidene acylhydrazide complexes in solution and at interfaces

    Author : Shoghik Hakobyan; Madeleine Ramstedt; Jean-Francois Boily; Mikael Elofsson; Marcus Textor; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antivirulent; Antibiofilm; Hydrazones; Gallium; Pseudomonas aeruginosa; Type three secretion system; Equilibrium constant; Chemical equilibrium modelling; Spectrophotometric titration; UV-Vis;

    Abstract : The growing bacterial resistance against antibiotics creates a limitation for using traditional antibiotics and requests development of new approaches for treatment of bacterial infections. Among the bacterial infections that are most difficult to treat, biofilm-associated infections are one of the most hazardous. READ MORE

  6. 4. A different approach to ecotoxicological characterisation of sewage effluent; using sensitive and ecologically relevant methods

    Author : Elin Lundström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Abstract Characterisation is used for quality assurance of effluent released into the environment. A different characterisation approach was in this thesis used for more sensitive and ecologically relevant whole effluent assessment. READ MORE

  7. 5. Ozonation in Advanced Wastewater Treatment : Practical Aspects and Development of a Prediction Tool for Pharmaceutical Removal

    Author : Rubén Juárez; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ozonation; wastewater; suspended solids; pharmaceuticals; bromate;

    Abstract : Pharmaceuticals that are not completely metabolized in the human body are excreted in wastewater and may find their way into surface waters, where they can have harmful effects on aquatic fauna and flora. The implementation of ozonation at wastewater treatment plants (WWTPs) can reduce the amount of pharmaceuticals discharged to the environment. READ MORE
