  • 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...

  • An investigation of alternative means of achieving water quality objectives

    Creator:
    Kerri, Kenneth Donald
    Abstract:
    Storage of water for water quality control is one of the alternative means of achieving water quality objectives. Authorities in the field of water quality management disagree regarding the use of precious water for the dilution of wastes. The costs of achieving water quality objectives by treatment of wastes at...

  • The degradation of kraft pulping wastes in estuarine waters

    Creator:
    O'Neal, Gary Lewis, 1938-
    Abstract:
    The degradation of kraft pulping wastes in estuarine waters was measured in terms of the following parameters: five-day 20°C B.O.D., the Pearl-Benson Index, and toxicity to the bay mussel (Mytilus edulis L.). The waste tested was the total effluent from a combined pulp and paper mill producing 430 tons of...

  • The present status of plastics as an engineering material

    Creator:
    Summersett, John Steve
    Abstract:
    The present status of plastics is one of constant change, but this thesis attempts to focus attention on the state of the industry as of 1967. Beginning with a brief title definition and history of plastics, the writer proceeds to a discussion on the structural characteristics of plastics. Under this...

  • 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 use of polymers for better settling in domestic waste treatment systems

    Creator:
    Houck, George Campbell
    Abstract:
    The author presents a "state of the art" of the use of polymers for better settling in domestic waste treatment and evaluates the published research in the field. Polymers have only recently been used to obtain better settling in domestic waste treatment. Due to the number of polymer types available...

  • Transport and adsorption of proteinanceous particles during flow through porous media

    Creator:
    Yamamoto, Tokuo
    Abstract:
    This is a fundamental study of the mechanism of protein particle removal during flow through sandy soil. Mathematical models for diffusion-adsorption and diffusion-convection-adsorption processes were developed and compared with experimental data. An attempt was made to calculate the distance over which the adsorption forces act. The differential equation for the...

  • Behavior of stream inflows to a stratifying field reservoir

    Creator:
    Chasse, James Peter
    Abstract:
    The behavior of a stream upon entering a field reservoir was studied at various stages of stratification. The principal field techniques included fluorometric and temperature surveys. General relationships were obtained, between dimensional and locational characteristics of the inflow current and the thermal structure of the impoundment. As predicted by analytical...

  • A study on the oxidation of sulfides in estuarine waters

    Creator:
    Korpalski, Thomas Paul
    Abstract:
    Waters of various salinities were secured from the Umpqua estuary, the Umpqua River, and the open ocean near the mouth of the estuary. The rate of oxidation of sulfides in these various waters was investigated to assess the potential longevity of free sulfides in estuarine waters. The rate of disappearance...
