Some aspects of the biological metabolism of a partially colloidal substrate

Creator:: Berg, Richard Harold
Abstract:: An investigation was conducted to ascertain if certain concepts of microbial metabolism, derived from studies using simple soluble substrates, are applicable to the biological assimilation of complex, partially colloidal suspensions. A mixture containing one gram of Carnation dry-skim milk is considered to be a complex, partially colloidal substrate and was...

Vertical jet diffusion in non linear density stratified fluid

Creator:: Baumgartner, D. J. (Donald John), 1933-
Abstract:: The simplified equations of motion proposed by Morton to determine the extent of vertical travel of a forced plume in a linear density stratified environment were re-written and solved in a way which allowed them to be applied to any non linear profile of density. For application to any specific...

Oxygen transfer in selected waste liquids

Creator:: Waki, Melvin Zane
Abstract:: A study to determine the oxygen transfer rates in selected waste liquids and to compare these rates with that of distilled water was performed. Tests using treated sewage and pulp and paper mill effluent were conducted in a model aeration tank. From the data, a, a ratio of the rate...

Disinfection of settled and unsettled trickling filter effluent by chlorination

Creator:: Monroe, Darrell Wayne
Abstract:: The colicidal efficiency of chlorine in both settled and unsettled trickling filter effluent samples was determined by means of a series of tests in which each sample was analyzed, at given time intervals, for suspended solids, pH, residual chlorine (orthotolidine and iodometric) and coliform count. A dye-tracer study, using Rhodamine...

High-shear and pressure activated sludge treatment : solid-liquid separation

Creator:: Coddington, Charles William
Abstract:: Since the development of the activated sludge process in 1913 many attempts have been made to improve it. One approach has been to increase the oxygen available to the bio-mass. This study combined the use of elevated pressure and high-shear mixing to increase the oxygen transfer. The conventional method of...

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...

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...

Nutrients in runoff from spray irrigation of swine wastes

Creator:: Taylor, Dennis William
Abstract:: Major emphasis of this research study involved the evaluation of nutrient transport by overland flow. Samples gathered at various distances relative to a swine-waste spray irrigation system were used for the nutrient evaluation. As a result of this study, the following conclusions are made: 1. It is improbable that the...

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...

Alum coagulation in conjunction with the activated sludge treatment of corn processing waste water

Creator:: Jensen, Harold LeRoy, III
Abstract:: The treatment of waste water from a corn freezing process by activated sludge with the aid of alum coagulation was investigated. Both high and low energy level systems were observed with good flocculation occurring at the low energy level. Because poor flocculation occurs at high energy level conditions, alum was...

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...

Effects of imbedded perforated pipes on permeability of gravelly stream beds

Creator:: Chu, Eddy Tak-hing
Abstract:: Perforated pipes were buried in the gravel bed of a laboratory stream, extending upstream from a simulated riffle in order to study their effect upon mixing and interchange of stream water and intragravel water. In the absence of such pipes the drop of energy gradient of the stream was concentrated...

Consumptive use of surface water by Willamette Basin municipalities

Creator:: Mittelstadt, Richard Lee
Abstract:: The consumptive water use of six cities in the Willamette Basin of northwestern Oregon was evaluated for the period 1960-66. Consumptive use ratios were obtained by analyzing data from monthly water supply and sewage flow records. The average annual consumptive use for the six cities was found to be 26...
