  1. 1. Hydrus-1D as a tool to understand contamination of an aquifer: A case study in the Central Valley of Cochabamba

    University essay from Lunds universitet/Teknisk geologi

    Author : Theo Nyberg; [2019]
    Keywords : Technology and Engineering;

    Abstract : In water resource management, it is of importance to be able to predict how different activities might contaminate aquifers. For this kind of application, numerical modelling of water and solute transport can be a useful tool. READ MORE

  2. 2. Development of a Water Activity Control and Reaction Monitoring System for Acidolysis and Transesterification Reactions using Immobilized Lipases in a Rotating Bed Reactor

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Eimantas Gladkauskas; [2019]
    Keywords : Enzyme; Enzymes; Immobilized enzyme; bioreactor; rotating bed reactor; acidolysis; transesterification; arduino; water activity; thermodynamic water activity; Enzyme activity; automatic reaction tracking; reaction tracking; biotechnology; electrical engineering; relative humidity; spinchem; enzymatic synthesis; water activity control; process automation; lipases; lipase; bioteknik; Technology and Engineering;

    Abstract : Controlled water activity in an enzymatic reaction can influence enzyme activity and productivity. A small layer of water around an enzyme gives it a required flexibility to catalyze reactions at a higher rate in contrast with the one that is dry (Adlercreutz, Dicko, Larsson, & Månsson, 2017).

  3. 3. Sustainable Drainage Systems Assessment and Optimisation-A case study for Lussebäcken Catchment, Helsingborg

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Bernard Nsabimana; Néstor Utande Estallo; [2019]
    Keywords : Hydraulics; hydrology; Sustainable Drainage Systems; urban; Modeling; MIKE URBAN; Technology and Engineering;

    Abstract : Increase of urbanization and climate change are one of the factors that have been highlighted to influence hydrography. This is resulting in an increase in peak flow within an urban watershed. Downstream flooding and increased pollution are the problems that arises. READ MORE

  4. 4. Hydraulics of lamella sedimentation.A study of the lamella settlers at Ringsjö water treatment plant, Sweden.

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Maria Lytra; [2019]
    Keywords : Lamella settling tanks; Inclined sedimentation; Ringsjö water treatment plant; Suspended solids separation; Technology and Engineering;

    Abstract : This study investigates the lamella settlers in Ringsjö water treatment plant, Sweden, in terms of water movement and performance. The treatment plant has two blocks with differences in the flocculation and lamella settlers, where block 1 is not able to process the maximum designed flow rate without the addition of polymers.

  5. 5. Methods for Evaluating Dewatering Properties of Sewage Sludge

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Nadia Abdalla; [2019]
    Keywords : sludge dewatering; sewage sludge; laboratory scale sludge treatment; dewatering sludge; dewatering sewage sludge; CST; capillary suction time test; centrifuge; lab-centrifuge; rheology; polymers conditioning; sludge conditioning; centrifuge on lab scale; evaluation of lab experiments; CST evaluation; mechanical de-watering evaluation; sludge dewatering at lab; lab scale dewatering process; sludge dewatering methods at lab; Chemical engineering; Lab centrifuge; Capillary Suction Time CST ; Mechanical sludge dewatering evaluation; Polymers conditioning of sludge; sewage sludge dewatering; methods for sludge dewatering at lab; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Chemistry;

    Abstract : After the sewage wastewater is collected from different households and directed to the treatment plants, it goes through several processes, which are physical, chemical and biological. The different processes remove the contaminant, and produce a semi-solid material named sludge. Sludge has a huge amount of liquid. READ MORE
