Beschreibungen/Notizen

• Chlorine is a common water purification agent, but can react to produce trihalomethanes (THM) and nonvolatile organics (NVCO). The contributions made by mixed populations of algae and by the green alga Scenedesmus sp. to this process were investigated using water from the Nile River dosed with high or low levels of chlorine. Concentrations of chloroform, dichlorobromomethane, and chlorodibromomethane increased during the contact periods. Chloroform was the dominant THM, and bromoform was not detected. Low doses of chlorine favored high production of THM and NVCO in the exponential growth period of Scenedesmus sp. High doses of chlorine increased THM production in exponential and stationary growth phases, and significant differences in NVCO production during different phases and at different doses was noted.
