  1. 1. Conservation Laws, Numerical Schemes and Control Strategies for Sedimentation and Wastewater Treatment

    Author : Sebastian Farås; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Conservation law; Temple class system; numerical scheme; continuous sedimentation;

    Abstract : A consistent theme throughout this thesis is quasilinear partial differential equations (PDEs) appearing in one-dimensional models of sedimentation for solid-liquid separation of suspensions. We mainly focus on continuous sedimentation in so-called clarifier-thickeners (CTs), which are found in mineral processing and wastewater treatment. READ MORE

  2. 2. Treatment conditions for the removal of contaminants from road runoff

    University dissertation from Stockholm : KTH

    Author : Magnus Hallberg; Gunno Renman; Jiri Marsalek; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dissolved matter; filter bed; particulate matter; sedimentation; suspended solids; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik;

    Abstract : The pollutant load in road runoff is related to traffic densities and road maintenance activities. Inurbanised areas treatment of road runoff is common and often considered necessary. The pollutantsare partitioned between the particulate and dissolved matter. However, the contaminantstend to have an affinity to the particulate material. READ MORE

  3. 3. Particulate Debris Spreading and Coolability

    University dissertation from Stockholm : KTH

    Author : Simone Basso; Pavel Kudinov; Florian Fichot; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-leveling; debris bed; spreading; coolability; severe accident; probabilistic framework; Monte Carlo; uncertainty; sensitivity; Fysik; Physics;

    Abstract : In Nordic design of boiling water reactors, a deep water pool under the reactor vessel is employed for the core melt fragmentation and the long term cooling of decay heated corium debris in case of a severe accident. To assess the effectiveness of such accident management strategy the Risk-Oriented Accident Analysis Methodology has been proposed. READ MORE

  4. 4. Towards an All-Embracing Elliptic Solver in 2D

    University dissertation from Stockholm : KTH

    Author : Rikard Ojala; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis addresses solving elliptic partial differential equation using integral equation methods, with emphasis on accuracy, speed and stability. Of particular interest are such equations on non-smooth domains, and several different elliptic problems such as electrostatic and elastostatic ones are treated and solved in this setting...

  5. 5. Anaerobic Digestion of Wastewaters from Pulp and Paper Mills A Substantial Source for Biomethane Production in Sweden

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Madeleine Larsson; Anna Karlsson; Bo H. Svensson; David Bastviken; Thomas Welander; [2015]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; wastewater treatment; biogas; methane; pulp and paper mill wastewater; pulp bleaching; wood raw material; Anaerob nedbrytning; vattenrening; biogas; metan; avloppsvatten från pappers- och massaindustrin; massablekning; träråvara;

    Abstract : The Swedish pulp and paper industry is the third largest exporter of pulp and paper products worldwide. It is a highly energy-demanding and water-utilising industry, which generates large volumes of wastewater rich in organic material. READ MORE
