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...

Effect of deposits in Columbia Slough on algae growth in Smith and Bybee lakes

Creator:: Sobolewski, William Joseph
Abstract:: Currently, the Port of Portland is developing a 9, 410 acre area at the confluence of the Columbia and Willamette Rivers in Multnomah County, Oregon. This area will be developed for industrial, commercial, and recreational use. The recreational development in the North Portland Peninsula area, including the Rivergate Industrial District,...

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...

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...

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...

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...

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 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...
