Description
Recent studies have demonstrated that ultra–violet (UV) effectively inactivates organisms such as giardia andcryptosporidium. However, the work has been primarily conducted with filtered waters. This research will investigate theimpact of variable water quality on the effectiveness of ultra–violet disinfection. UV avoids many of the harmfulby–products, such as chloramines, associated with conventional disinfection technology. This study will investigate theimpacts of turbidity, algae, and total organic carbon on potable water disinfection with UV. It may also identifyopportunities to lower both the future capital cost of a water treatment plant and operating and maintenance costs. Theinstallation of UV disinfection on the water supply would also allow for consideration of complete water treatmentdeferment and the avoidance of chlorination.
