RISCreep Crack Growth Behavior in Power Plant Boiler and Steam Pipe Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the important ingredients in remaining creep crack growth life assessment of elevated temperature power plant components is the material creep crack growth rate data. This report summarizes ...
Strong Tough HSLA Steels Via Processing and Heat Treating of Cu-Ni-Cb and Cu-Ti-B Compositions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper deals with the development of control-rolled Cu-Ni-Cb HSLA steels with increased section capability for low-temperature environments and Cu-Ti-B HSLA steels for general structural ...
Performance Evaluation of Aerated Lagoon in Summer and Winter Conditions
Publisher: American Society of Civil Engineers
Abstract: A 1-year study evaluated the performance of a full-scale aerated lagoon, located in a midwest community in the United States. The objective of this study was to evaluate the performance of the lagoon under varied temperature ...
Performance Evaluation of Overland Flow Wastewater Treatment System under Winter and Summer Conditions
Publisher: American Society of Civil Engineers
Abstract: A study was conducted to evaluate the effects of seasonal variations, summer and winter conditions, on the performance of an existing and successfully operated overland flow wastewater treatment system in the Midwest. The ...
Chromium(VI) Removal by Modified PVP-Coated Silica Gel
Publisher: American Society of Civil Engineers
Abstract: This research involved the synthesizing of a reactive polymer, long alkyl quaternized poly(4-vinylpyridine) (PVP), and coating it onto the surface of silica gel to produce a granular sorbent to remove Cr(VI) from water. ...
Factors Affecting Chromium(VI) Removal by Modified Poly(4-Vinylpyridine) Coated Silica Gel
Publisher: American Society of Civil Engineers
Abstract: A reactive polymer, alkyl quaternized poly(4-vinylpyridine) (PVP) was synthesized and coated on the surface of silica gel to test its ability to remove Cr(VI) from water. Batch experiments were conducted with the coated ...
Interaction of Metal and Other Contaminants Present in Sludge and Soil
Publisher: American Society of Civil Engineers
Abstract: Laboratory experiments were conducted to evaluate the interaction of metals (As, Cd, Cr, Cu, Pb, and Ni) and nitrate-N present in municipal sludge with a soil sample. The soil selected for this experiment was Menfro silt ...
Microbiological Stabilization of Sludge by Aerobic Digestion and Storage
Publisher: American Society of Civil Engineers
Abstract: A study is conducted to evaluate the pathogen and indicator bacterial reductions in the sludges of two wastewater‐treatment plants. These plants are extended‐aeration and oxidation‐ditch‐type plants that have no aerobic ...
Performance Evaluation of Constructed Wetland Treatment System
Publisher: American Society of Civil Engineers
Abstract: The objectives of this study were to determine effective vegetation species that had the ability and efficiency to improve the effluent quality of an existing wastewater wetland treatment system. Channels were constructed ...
Atrazine Removal through Biofiltration
Publisher: American Society of Civil Engineers
Abstract: Atrazine is a common contaminant of many surface-water supplies in Missouri and other areas in the midwestern United States. It is classified by the Environmental Protection Agency as a group C–possible human carcinogen, ...
