Evaluation of Two-Species Model for Chlorine Decay and THM Formation under Rechlorination Conditions
(No paper) Typically, chlorine decay has been described by a first-order decay model. The first-order model, however, has two drawbacks: 1) the reactive species within the water is assumed...

The Effect of UV Radiation on THM Formation in Drinking Waters
This study was undertaken to investigate the feasibility of using combined UV radiation/chlorination process in drinking water treatment for disinfection while producing lower concentrations...

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...

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...

Alternatives for Control of Color and THMs in a Fort Lauderdale Water Supply

Chloramines: A Better Way?
Chlorination of drinking water has been linked to the formation of carcinogenic trihalomethanes (THMs). By adding ammonia to the water, the chlorine becomes chloramines which don't...

Treatment Plant Comparisons in Removing Molecular Weight Fractions of THM Precursors
This paper describes the performance of several types of water treatment plants in removing various molecular weight fractions of natural occurring aquatic organic matter, some of which...

Direct Filtration of Colored Water Supplies
The effects of raw water quality, chemical treatment, and filtration variables on the performance of direct filtration are examined. Cationic polyelectrolytes as sole coagulants are effective...

Boston MDC Experience With Chloramine Disinfection
In May, 1982, as a condition for approval of plans for improvements to the Metropolitan District Commission (MDC) chlorination facility at Norumbega Reservoir, the Massachusetts Department...
