  • 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...

  • The character and biological treatability of log pond waters

    Creator:
    Hoffbuhr, Jack Wayne
    Abstract:
    A study was conducted to determine the chemical nature and the biological treatability of log pond water. Various analyses including total solids, volatile solids, suspended solids, dissolved oxygen, pH, COD, BOD₅, BOD₂₀, total Kjeldahl nitrogen, nitrate nitrogen, phosphate, and PBI were performed on water samples from each of the four...
