Stratification in Laboratory Simulations of Water Hyacinth Ponds
Publisher: American Society of Civil Engineers
Abstract: The technical and economical feasibility of using water hyacinth ponds for the treatment of wastewater is well established. However, various purification mechanisms operative in a pond have not been understood fully. In ...
Effect of Flyash Addition on the Quality of Al-11%Si Alloy Castings Produced by V-Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Energy is important for modern civilization and the electrical power from thermal stations is a major source of energy on which hinges the functioning and growth of mankind. In almost all ...
Biological Phosphorus Removal: Effect of Low Temperature
Publisher: American Society of Civil Engineers
Abstract: Phosphorus is a key nutrient responsible for eutrophication. Conventional activated sludge process (ASP) removes approximately 30 to 40% phosphorus. Additional phosphorus removal has been achieved by incorporating an ...
Characterization of Aqueous Organics by Specific Ultraviolet Absorbance and Octanol Water Partition Coefficient
Publisher: American Society of Civil Engineers
Abstract: Specific ultraviolet absorbance (SUVA) is the ratio of ultraviolet absorbance (UVA) to dissolved organic carbon (DOC) or UVA per unit of DOC. The octanol water partition coefficient (
Anaerobic Degradability: Effect of Particulate COD
Publisher: American Society of Civil Engineers
Abstract: Batch bioassay tests were conducted to evaluate the effect of particulate chemical oxygen demand (COD)
Sorption of Aqueous Organics by Aquifer Material: Correlation of Batch Sorption Parameters with Octanol-Water Partition Coefficient
Publisher: American Society of Civil Engineers
Abstract: A study of sorption of aqueous organics by aquifer materials was undertaken with an objective to correlate sorption parameters with the octanol-water partition coefficient (KOW) of aqueous samples. In the first phase, ...
Use of Sequencing Batch Reactor for Biological Denitrification of High Nitrate-Containing Water
Publisher: American Society of Civil Engineers
Abstract: The efficiency of a sequencing batch reactor in denitrification of drinking water with relatively high nitrate concentrations (40–250 mg/L as N) was evaluated. Ethanol at a COD/N of 2.00 was found sufficient to reduce ...
Biodegradation of Phenol with Wastewater as a Cosubstrate in Upflow Anaerobic Sludge Blanket
Publisher: American Society of Civil Engineers
Abstract: Anaerobic degradation of phenol mixed with a readily degradable synthetic wastewater (DSWW) as a cosubstrate was studied in a
Simple Model for Structural Evaluation of Asphalt Concrete Pavements at the Network Level
Publisher: American Society of Civil Engineers
Abstract: Evaluation of the structural conditions and estimation of the remaining structural life of each pavement section are important considerations for prioritizing the maintenance needs of any highway network. Many highway ...
