Impact of Preozonation on Trihalomethane Formation
On the Road to Clean Air
Anticipating passage of the 1990 Clean Air Act in the fall of the year, this article examines the remaining air quality problems in U.S. cities and some efforts underway or being planned...
The Potential Effects of Global Climatic Disruption on Coral Reef Ecosystems
Ozonation of a Biorefractory Organic Compound
This study involved determination of the degradation of chlorendic acid due to ozonation, possible biodegradation of the resultant products, and possible toxicity of the resultant products....
Full-Scale Evaluation of Filter Influent Chlorination and Ozonation
Ozone and chlorine applied ahead of pressure filters are compared to determine the effect of the chemical addition on the pressure differential across the filter bed. The study was significant...
Role of State Department in Environmental Issues
The Department of State plays a key role in resolving international environmental issues. This paper describes how the Department is organized to deal with environmental concerns, discusses...
The Ozone Defense
Ozone is a molecule containing three oxygen atoms. When bubbled through drinking water, the third atom in ozone is attracted away by other molecules, a process called oxidation. This process...
Are the Soil Depositions in Mexico City Unique?
The answer clearly is: YES| However, the amplification and soil-structure interaction effects observed in Mexico City are important considerations - even if they may not be so severe -in...

Ozoning the Aqueduct
Only the second of its kind in the United States, the Los Angeles Aqueduct Filtration Plant is using ozone to treat drinking water. The water comes from the Sierra Nevadas via the 300...
Evaluation of Chlorine Dioxide and Ozone Preoxidation on Conventional Treatment and Direct Filtration
The renewed interest in the use of chlorine dioxide and ozone as preoxidants has focused mainly on their effectiveness on color and THM precursor removal and as disinfectants. This paper...
