What kind of testing has been done on UV disinfection systems?
UV disinfection is a safe and well-understood process that has been used for more that 100 years. Similar to a number of commercial water treatment plants in Europe and the United States, UV Tubes use ultraviolet (UV-C) light emitted from a germicidal bulb to inactivate waterborne bacteria, viruses and protozoa. The only difference with commercial systems is that UV Tubes are easy to use and can be constructed from locally available and low-cost materials. The UV Tube has been developed by the University of California at Berkeley based on rigorous testing carried out both in laboratories and field conditions throughout the past five years. Extensive laboratory analysis has been performed on the UV Tube. These tests include tracer studies to determine the hydraulic retention time, MS2 tests to identify the dose of UV-light delivered, and membrane filtration experiments to measure disinfection performance. A materials degradation test has also been conducted to clarify if any disinfectio
