Synergies of UV Disinfection and Ozone in Water Treatment
Two case studies outlining the benefits of using ozone and UV are presented in this paper. They demonstrate the cost effectiveness and robustness that can be observed when the synergies of these two treatment alternatives are utilized. In the first study, ozone and UV disinfection were used at the Weber Basin Water Conservancy District’s Water Treatment Plant No. 3. The ozone system was designe...
متن کاملMutagenic activity associated with by-products of drinking water disinfection by chlorine, chlorine dioxide, ozone and UV-irradiation.
A retrospective epidemiological study in The Netherlands showed a statistical association between chlorination by-products in drinking water and cancer of the esophagus and stomach for males. A pilot-plant study with alternative disinfectants was carried out with stored water of the Rivers Rhine and Meuse. It was demonstrated that the increase of direct acting mutagens after treatment with chlo...
متن کاملModelling of Disinfection by-products formation via UV irradiation of the water from Tajan River (source water for Sari drinking water, Iran)
Background & Aims of the Study Irradiation with ultraviolet light (UV) is used for the disinfection of bacterial contaminants in the production of potable water. The main objective of the study was to investigate and model Disinfection By-Products (DBPs) formation due to the UV Irradiation of the Tajan River water under different Irradiation conditions. Materials & Methods: &nbs...
