Local Area Network Communications Testing
This paper presents the philosophy developed for benchmark communications testing in networks typical of CAD/CAM environments. Implementation of the test philosophy in a connectionless...

Control of Nocardia in a Municipal Activated Sludge Facility
The paper reports on a study to determine the cause(s) of the biological imbalance and identify corrective measures. Project activities included: isolation and identification of filamentous...

Comparison of Preozonation and Prechlorination in the Treatment of Several Raw Water Supplies
Bench scale testing of 18 raw water supplies from various locations throughout the eastern United States was conducted to evaluate their susceptibility to ozonation, and to compare preozonation/conventional...

A Local Approach to Regulating Toxic Air Contaminants
The Monterey Bay Unified Air Pollution Control District began developing a local toxic rule that would apply to a broad number of pollutants and yet be readily usable to a permitting engineer....

Mini/Micro Hydro Applications in Remote Off-grid Areas of Ontario
This paper outlines the potential for remote off-grid small hydro development in Ontario and the present incentives that exist to develop these resources. Estimated costs of development...

Recent Developments of the Finite Strip Method
The finite strip method is approaching a state of maturity as a structural analysis technique, as the well known finite element method has done. Two comprehensive (although somewhat dated)...

Performance of Existing Buildings: Results of Benchmark Structure Analyses Performed in U.S.-Japan Workshops
In response to the need for better understanding of current safety evaluation methodologies, three U. S. -Japan workshops have been conducted on the evaluation of the performance of existing...

Leaching Characteristics of Metal Finishing Sludges
The purpose of this research was to study the feasibility of biodegrading phenolics to methane by thermophilic anaerobic treatment. The study was a feasibility level assessment which examined...

Oxygen Transfer Studies in Activated Sludge
A bench-scale research project was undertaken to evaluate the two-film model for predicting oxygen transfer rates in sparged suspended growth systems and to determine if interfacial oxygen...

A Bench-Scale Study of Wastewater Aquaculture Using the Duckweed
A continuous flow bench scale reactor was used to evaluate nutrient removal and growth characteristics of the duckweed, Lemna minor. Such a system can further an understanding of the treatment...

Impact of Dynamic Loading on Bio-Phosphorus Removal
The ability of bench-scale activated sludge biological phosphorus removal systems to produce effluents with consistently low phosphorus concentrations was influenced by influent TOC/COD...

Aggregation and Consolidation of Phosphatic Clays
The consolidation behavior of aggregated phosphatic clays has been investigated using a bench scale centrifuge. It was determined that aggregation of the clays with phosphogypsum, a waste...
