Development And Verification Of A Laboratory Model For Use In The Study Of A Continuous Flow Pressurized Activated Sludge Process, Wayne Frederick Nolte
Development And Verification Of A Laboratory Model For Use In The Study Of A Continuous Flow Pressurized Activated Sludge Process, Wayne Frederick Nolte
Dissertations
Investigations concerning the responses of domestic wastewater treated at elevated pressures have demonstrated an acceleration in the rate of biological assimilation of the waste material. The literature is not extensive, but presents much conflicting data. There has been a lack of a coherent approach to the investigation of pressure in wastewater treatment. This demonstrates the need for standard testing apparatus and procedures.
A bench scale pressurized activated sludge process was designed and constructed. The apparatus was tested over a broad range of conditions and was found to give reproducible results. Kinetic responses of the pressurized process are presented.

The Use Of Natural Sorbents For The Treatment Of Industrial Sludge Leachate, Mung Shium Jack Sheih
The Use Of Natural Sorbents For The Treatment Of Industrial Sludge Leachate, Mung Shium Jack Sheih
Dissertations
A sorbent treatment process has been developed which uses natural clay soils and fly ashes as sorbents in the treatment of the hazardous contaminants of potential sludge leachate emanating from industrial landfills. Natural sorbents (i.e., vermiculite, illite, kaolinite, zeolite, acidic and basic fly ashes) were evaluated for the removal of specific cations, anions, and organics from leachates generated from three industrial sludges (i.e., calcium fluoride, metal finishing, and petroleum). The laboratory results indicate that, rather than a single sorbent, a combination of acidic and basic sorbents in a layered system is required to reduce for the measurable contaminants present in …

Stress-Strain Properties Of Compacted Modified Memphis Loess, Danny Lloyd Kerns
Stress-Strain Properties Of Compacted Modified Memphis Loess, Danny Lloyd Kerns
Masters Theses
"A study was made of the stress-strain characteristics of compacted samples of a modified loessial soil obtained near Memphis, Tennessee. The study consisted of compacting samples at a constant water content and at unit weights of 92, 96 and 100 pounds per cubic foot (1470, 1540 and 1600 kg/m3). Triaxial tests were performed on unsaturated compacted specimens to obtain stress-strain-volume change data. These data were used to determine stress-dependent functions for tangent modulus and Poisson's ratio"--Abstract, page ii.

Photogrammetric Digitizing System, Frank Richard Gorshe
Photogrammetric Digitizing System, Frank Richard Gorshe
Dissertations and Theses
The acquisition of terrain data from aerial photography using digital photogrammetric methods gives the engineer and planner an economical alternative to conventional ground surveys. This paper describes a complete photogrammetric digitizing system developed for the Portland District Army Corps of Engineers. The hardware of the system consists of a
Wild AlO first order stereoplotter interfaced to an Altec AC-74 coordinate digitizer which is interfaced to both a Hewlett Packard 9810A programmable calculator and a Digi-Data nine-track magnetic tape recorder. The software of the system consists of photogrammetric routines developed for online computation by the programmable calculator and a sophisticated FORTRAN …
