How Hydrorite Works & Specifications - Hayward HydroRite UVO3 Troubleshooting Manual

The Hayward HydroRite contains 3 high intensity electrically
operated Ultraviolet (UV) lamps. The UV lamps emit light at
two separate wavelengths within the UV spectrum; 254 nm
and 185 nm.
• The 254 nm wavelength is considered the "germicidal"
wavelength. This wavelength is capable of inactivating a
wide array of microorganisms such as bacteria, viruses,
protozoa (e.g. Cryptosporidium and Giardia), algae
spores and other single vessel waterborne microbes.
• The 185 nm wavelength, on the other hand, is
considered the "ozone generating" wavelength and is
responsible for converting oxygen (O²), contained in the
quartz sleeve area, into ozone (O³). The ozone created is
introduced into the water stream using a venturi. Ozone,
a strong oxidizer and bactericide in its own right, works
collaboratively with the UV to oxidize bather waste and
inactivate microorganisms utilizing a process known as
"advanced-oxidation".
