Does the ultraviolet light react with oxygen to form ozone, which can be hazardous to people?
Ozone can be produced from oxygen exposed to UV light in the region of 140nm to 190nm. Ozone absorbs UV light in the region of 220nm to 280nm, effectively transforming the ozone molecules back into oxygen. The low-pressure mercury bulbs used by the UV Tubes emit a low intensity line at 184.9nm that has the capability of producing ozone. However since most of the energy emitted by the bulbs is produced at 253.7nm, the little ozone that is produced almost instantly transforms back into oxygen. Because of this, no ozone builds up inside a UV Tube and no ozone ever escapes the UV Tube. With what types of water supply systems can the UV-Tube be paired? The UV-Tube employs a flexible design concept that can be adapted to fit a variety of water supply situations, including piped water, rainwater catchment systems, wells, or springs. What does the UV-Tube need to operate? The UV Tube is powered by electricity and therefore must be connected to a reliable electricity source, i.e. grid or solar
