Effects of pressure and deposit thickness on the stabilization rate of benthic marine sludge deposits

Creator:: Muellenhoff, W. P.
Abstract:: The biochemical degradation of domestic sludge deposits exposed to benthic marine conditions was investigated using a laboratory Deep Sea Simulator. The rate and extent of deposit stabilization were determined for select hydrostatic pressures and hydrogen acceptor conditions by monitoring depletion of particulate organic carbon in 2.0 and 3.0 centimeter deposits....

A manual for plate loading tests performed on rock

Creator:: Dodds, Donald J.
Abstract:: Plate loading tests in rock are deceptively simple tests to perform. Consequently, many varieties have been developed in the past 60 years. From each of the varieties various investigators have added their own developments and modifications, some good, and some not so good. The result has been a confusion of...

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...

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...

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...

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 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...
