  1. 1. Modelling of a sulfate reducing and metal recovery process, for application within treatment of industrial wastewater

    University essay from Lunds universitet/Bioteknik (master)

    Author : Kristina Broberg; [2019]
    Keywords : Biotechnology; Wastewater treatment; Process modelling; Bioprocess technology; Sulfate reducing bacteria; Metal sulfides; Simulation; Matlab; SuperPro Designer; Bioteknik; Technology and Engineering;

    Abstract : Denna masteruppsats syftar till utvecklandet av en industriellt, fullskalig modell över en vattenreningsprocess som syftar till simultan sulfatreduktion och tungmetallåtervinning från processvatten vid gruvdrift. Den mängd sulfat som finns tillgänglig i lakvattnet, omvandlas till vätesulfid med hjälp av sulfatreducerande bakterier (SRB). READ MORE

  2. 2. Optimal steady-state design of bioreactors in series with Monod growth kinetics

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Molin Hanna; [2018]
    Keywords : bioreactor; CSTR; PFR; optimization; modelling; Monod kinetics; decay rate; bioreaktorer; CSTR; PFR; optimering; modellering; Monod-kinetik; avdödningshastighet;

    Abstract : Bioreactors are used to carry out bioprocesses and are commonly used in e.g. biogas production and wastewater treatment. Two common hydraulic models of bioreactors are the continuous stirred tank reactor (CSTR) and the plug-flow reactor (PFR). READ MORE

  3. 3. Modeling of Concentration Profiles in Yeast Capsules for Efficient Bioethanol Production

    University essay from Chalmers tekniska högskola/Institutionen för kemi- och bioteknik

    Author : Riani Ayu Lestari; [2010]
    Keywords : Simulation; Modelin; Diffusion-Reaction process; Encapsulated yeast; Comsol Multiphysics;

    Abstract : Encapsulated yeast can be used for increasing bioethanol production during fermentation of inhibitory lignocellulose hydrolysates. It is useful for decreasing the effect of inhibitors when the substrate through the capsule. It can be considered as a spherical pored catalyst, which contains yeast within the capsule. The capsule has 3 main parts, i. READ MORE

  4. 4. Low Order Approximations of Continuously Stirred Biofilm Reactors with Monod Kinetics

    University essay from Chalmers tekniska högskola/Institutionen för signaler och system

    Author : Elin Göransson; [2004]
    Keywords : ;

    Abstract : Design of controllers and optimization of plants using biofilm reactors often require dynamic models and efficient methods of simulation. Continuously stirred biofilm reactors (CSBRs) are useful model units in modeling of a variety of different biofilm reactors. Often the reaction kinetics in the biofilm is described by a Monod expression. READ MORE
