How is Ozone generated in the Zuvo Purator?
The Zuvo Purator uses a “broad spectrum” UV lamp. In addition to visible light, the Zuvo Purator UV lamp emits shortwave UV energy across a band of wavelengths from 160 nanometers to 260 nanometers (hence the term “broad spectrum”). These two key UV wavelengths are fundamental to the Zuvo performance. At 185 nanometers, UV energy breaks apart oxygen molecules in air. Because oxygen atoms are highly unstable, some of these recombine with other oxygen molecules to form ozone. Chemically, this is O + O2 = O3. This reaction takes place in the space between the UV lamp and the quartz sleeve in the Zuvo unit. The ozone is then siphoned through a tube attached to a Venturi (a simple device that creates a vacuum from a pressure differential) and infused into the inlet stream of water, where it creates the bubbles that swirl up in the Purator chamber. These bubbles are a combination of air and ozone in the gas phase. Some of the ozone is actually dissolved into the water through the Venturi and
