    Sammanfattning : The gap between resource demand for the industrialized world and non-renewable feedstock like fossil fuels, essential agricultural fertilizer is getting increasingly severe, which has resulted in alarming-increasingly impacts on worldwide environmental problems. Meanwhile, wastewater treatment plants (WWTPs), as an essential facility for urbanization, is also confronting new rising challenges such as energy consumption and operation costs rather than only improving effluent wastewater quality.

  5. 19. Towards autonomous antibody purification

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Frida Heskebeck; [2019]
    Nyckelord :Chemical engineering; Kemiteknik; Simulation; Chromatography; Periodic counter-current chromatography; Python; PCC; Technology and Engineering;

    Sammanfattning : The vision of antibody purification is to have the whole process fully automatic. It is often desirable to have a continuous process since that reduces the costs for production and the size of the used equipment. It is necessary to supply buffer solutions to the purification steps, and as part of the vision; this should be done automatically. LÄS MER
