  • Treatment of activated sludge process effluent by carbon adsorption

    Creator:
    Davis, Stewart Lee
    Abstract:
    An evaluation of the service time of an activated carbon adsorption column and the organic carbon removal efficiency treating activated sludge process effluent was completed at aerator detention times of three, five, and ten hours. Parameters used for evaluation of treatment were biochemical oxygen demand, chemical oxygen demand, total organic...

  • The effect of elevated pressure on the activated sludge process

    Creator:
    Godsil, Patrick James
    Abstract:
    A study of the effect of elevated pressure on the activated sludge waste treatment process is presented. The method of study involved a comparison of two laboratory, batch type, activated sludge units. One unit was operated at atmospheric pressure as a base control and the other operated at elevated pressures...

  • The effect of elevated pressure and high shear on oxygen uptake rates in activated sludge

    Creator:
    Streebin, Leale E.
    Abstract:
    The purification capacity of an activated sludge process is highly dependent of the rate of oxygen transfer from the air to the microorganisms. This rate can be increased in an air diffusion system by subjecting the culture to high shear and high pressure. A study of the effects of high...

  • Metabolic uncoupling of Shewanella oneidensis MR-1, under the presence of excess substrate and 3,3’,4’,5 tetrachlorosalicylanilide

    Creator:
    Saini, Gaurav
    Abstract:
    Dissociation between catabolism and anabolism, generically termed “metabolic uncoupling”, has been studied for aerobic cultures of Shewanella oneidensis MR-1. Under conditions promoting metabolic uncoupling, the cell yield diminishes while the substrate utilization rate remains largely unchanged. The effects of excess substrate conditions and TCS addition on the metabolism of pyruvate...
