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...

Using Distribution System Modeling to Evaluate Treatment Plant Disinfection By-Product Control Strategies

Predicting THM Formation with Artificial Neural Networks
An existing mathematical model to predict trihalomethane formation and speciation was enhanced through the use of artificial neural network technology. The model corresponded well with...

Trihalomethanes in Chlorinated Sacramento-San Joaquin Delta Drinking Water Simulated with the EPA WTP-THM Model
Trihalomethane (THM) concentrations at a representative water treatment plant simulated with the EPA Water Treatment Plant THM (WTP-THM) model were used to assess potential drinking water...

Simulating THM Precursors Transport with DWRDSM
A study was conducted by the California Department of Water Resources (DWR) to demonstrate the ability of its Delta Simulation Model (DWRDSM) to simulate fate and movement of inorganic...

Removal of Trihalomethane Precursors by Ferric Chloride Coagulation

Trihalomethane Precursor Removal by Ozone and Ultraviolet Radiation
The research objectives were definition of trihalomethane formation potential (THMFP) reduction in groundwater matrix using ultraviolet radiation (UV) catalyzed ozone oxidation (UV/Ozone)....

Trihalomethane Control: A Case Study
Controlling trihalomethanes (THMs) has been an important part of many utilities' water treatment programs since THMs were first regulated in 1979. The increased disinfection...

Impact of Preozonation on Trihalomethane Formation

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...

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

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...

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...
