    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

  2. 2. Options for Mechanical Hold Force for Sliding Doors

    University essay from Lunds universitet/Produktutveckling

    Author : Mikaela Albertsson; Jens Thieme Almkvist; [2019]
    Keywords : Sliding doors; Mechanical force; Product development; Ulrich Eppinger; Prototyping; Technology and Engineering;

    Abstract : ASSA ABLOY’s automatic sliding doors today have a constant hold force applied whenever the doors are closed. The force is adjustable between 0-60 N and is generated by a motor. In this project it has been investigated whether it is possible to install a mechanical alternative to this hold force instead. READ MORE

  3. 3. Mechanical and Thermal Characterisation of Polymer Films Exposed to Filling Products

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Erik Vu; [2019]
    Keywords : polymer technology; polymerteknologi; Technology and Engineering; Chemistry;

    Abstract : Knowledge on how polymeric materials changes or is affected when exposed to products is of interest and importance for many commercial applications. Understanding the product interaction on packaging materials is the key to preventing errors and increasing the quality of products. READ MORE

  4. 4. The Dissipating Energy Flow method for analysing generator contribution to power system damping -- evaluation and interpretation

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Hampus Möller; [2019]
    Keywords : Electromechanical oscillations; small-signal stability; energy flow; PMU measurements; forced oscillations; dissipating energy.; Technology and Engineering;

    Abstract : Electromechanical oscillations is a power system phenomenon where generator rotors oscillate, leading to oscillatory power flows. Damping of such oscillations is important for system stability. Forced oscillations is a special case where one faulty component is the source of the oscillation. READ MORE

  5. 5. Design of an Autonomous Weeding Vehicle

    University essay from Lunds universitet/Produktutveckling

    Author : Simon Axbom; Lisa Ralsgård; [2019]
    Keywords : Mechanical Engineering; Product Development; Agricultural Robotics; Weeding; Lightweight Vehicle; Technology and Engineering;

    Abstract : This thesis describes the development of an autonomous weeding vehicle for the agricultural industry. It has been done as a project at RMIT University in Melbourne and the aim was to develop a design for the vehicle which could later be used to develop a commercial product. READ MORE
