Fate and Effect of Carbon Tetrochloride and O-Xylene on Anaerobic Systems with Sulfate Reducing Bacteria
The fate and effects of o-xylene and carbon tetrachloride on methanogens and sulfate reducing bacteria were investigated using serum bottles. Up to 750 mg/1 of o-xylene did not cause any...

Potential Effects of Global Climatic Change on the Tennessee Valley Authority Reservoir System
Rising concentrations of carbon dioxide (CO2) and other 'greenhouse' gases are likely to increase global temperatures and...

Preliminary Analysis of Fire Suppression Methods for the Space Station
The choice of a fire suppression system for the space station remains open. Several alternatives have been suggested, each with particular advantages and disadvantages. The problem is...

Oxygen Production for a Future Lunar Base
This paper discusses various ways for providing oxygen for a lunar base. Currently, there are three methods available which are technologically possible. One of these is the use of chemical...

Bugs and Carbon Make a PACT
At its Chambers Works in southern New Jersey, DuPont was ordered to sharply reduce the BOD load in the wastewater it discharged to the Delaware River. Out of this mandate came the PACT...

Detoxifying Metal-Contaminated Solid Wastes by Induced Ion Exchange—A Theoretical Evaluation
The presence of minor amounts of insoluble heavy metal precipitates may render a large body of innocuous solids (say fly ash, soil, calcium carbonate or even biological sludge) potentially...

Removal of EDB from Groundwater by Granular Activated Carbon Filtration
Application of ethylene dibromide (EDB) pesticide to crops may result in contamination of groundwater. Various water treatment alternatives are: granulated activated carbon adsorption,...

What About the Point-of-Use?
Point-of-use (POU) granular activated carbon (GAC) treatment devices are being installed more frequently on community water sytems and on private wells. This article describes carbon filter...

The Ultimate High Tide
Unprecedented consumption of fossil fuels and clearing of vegetation have spurred interest in the greenhouse effect. Under this scenario, a build-up of carbon dioxide and other gases in...

Rehabilitation of a Pump/Turbine
Between 1964 and 1968, eight 212 in pump discharge diameter Baldwin-Lima-Hamilton vertical pump/turbines with Westinghouse motor/generators were installed in Philadelphia Electric Company's...

Carbon Columns: Success at Last
The first large scale application of carbon columns for municipal wastewater treatment has been operating for two years. The columns were designed as part of a program to upgrade an out...

Water Quality Modeling of Key Largo Coral Reef
A numerical model called CORALSIM has been developed for the Key Largo Coral Reef National Marine Sanctuary in the Florida Keys. The model was developed as a management tool to study the...

Characterization of Indoor Carbon Monoxide Levels Produced by the Automobile
