HydroRite: How It Works
The Hayward HydroRite contains a high intensity electrically operated Ultraviolet (UV)
lamp which is located inside the unit's wet chamber. The UV lamp emits light at two
separate wavelengths within the UV spectrum; 254 nm and 185 nm.
The 254 nm wavelength is called 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 vesseled
waterborne microbes. The 254 nm UV light alters the DNA and RNA of the
microorganisms rendering them incapable of infection.
The 185 nm wavelength, on the other hand, is called the "ozone generating"
wavelength and is responsible for converting oxygen, contained in the quartz sleeve
area, into ozone. The ozone created is introduced into the water stream using a
venturi. Ozone, a strong oxidizer and bactericide in its own right, works together with
the UV to oxidize bather waste and inactivate microorganisms utilizing a process
known as "advanced-oxidation".
