Trihalomethane Precursor Control by Adsorption

Journal of the Environmental Engineering Division, 1981
The purpose of this project was to study the effectiveness synthetic resins and activated carbon to control trihalomethana precursors (THMP) in a finished drinking water which has the Missouri River as its principal source. As will be shown herein, a net reduction in THMP cannot necessarily by assumed when an adsorption process is being utilized.

Removing Trihalomethane Precursors by Coagulation

Journal AWWA, 1987
The removal of trihalomethane precursors by coagulation was studied with low turbidity, low alkalinity waters containing high levels of aquatic humic matter. Jar tests were conducted with synthetic and natural waters using alum, high‐molecular‐weight polymers, cationic polymers, and various combinations of these coagulants. Cationic polymers alone were

Uptake of trihalomethanes by patients during hemodialysis

Clinica Chimica Acta, 1989
Trihalomethanes (THM) present in tap water were also found in dialysis fluid because they were not eliminated by water treatment. THM, absorbed through the dialyser membranes, increased considerably in blood and in expired air of patients on hemodialysis during the dialysis sessions. The uptake of THM during each dialysis session was about 1 mg.

Trihalomethanes in Drinking Water and Spontaneous Abortion

Epidemiology, 1998
Trihalomethanes (chloroform, bromoform, bromodichloromethane, and chlorodibromomethane) are common contaminants of chlorinated drinking water. Although animal data indicate that these compounds may be reproductive toxicants, little information exists on their relation to spontaneous abortion in humans.

Trihalomethane Formation in Open Reservoirs

Journal AWWA, 1991
Historical records were used to characterize the quality of water in an open distribution reservoir with respect to trihalomethanes (THMs) and total organic halides and to explore the effect of algae, chlorine use, and reservoir bypass operation on THM formation.

Trihalomethane Formation Potential and Disinfection

Water Quality Research Journal, 1992
Abstract The UVOX process was developed to reduce the high concentrations of trihalomethanes, a potentially hazardous disinfection by-product found in a surface water supply for a community in northeastern Saskatchewan. Pilot plant tests were conducted at a throughput of 1.25 l/s utilizing UV to produce hydroxyl radicals from photolysis ...
