  • A motor-generator and supercapacitor based system for microgrid frequency stabilization

    Creator:
    Crispo, Richard F.
    Abstract:
    This research introduces an energy storage system to deliver microgrid frequency response. A doubly-fed induction generator (DFIG) and a squirrel cage induction machine (SCIM) are coupled together as a motor/generator set to deliver an immediate inertial response to a change of frequency, and an inverter and supercapacitors deliver short term...

  • Exploration of Simultaneous Anammox and Denitrification (SAD) Biofilm Processes for Nitrogen Removal

    Creator:
    Hilliard, Richard F.
    Abstract:
    Anammox (anaerobic ammonium oxidation) bacteria are capable of providing low-cost nitrogen removal for numerous types of wastewaters. However, low growth rates cause long startup-times and inhibition by oxygen and metabolic substrates necessitate close process control to maintain performance. Incorporation of Simultaneous Anammox and Denitrification (SAD) into constructed wetlands could provide...
