How it works

It has been long known that ultraviolet lamps at a wavelength of 254 nanometers, or 2537 Angstrom, have high bactericidal, virucidal and algicidal properties. Type C ultraviolet eradicates germs by aggressively disrupting the cell metabolisms leading to their destruction. These lamps should not be mistaken for ozone producing lamps, which operate at different wavelengths. Ultraviolet radiation is measured in micro watts/second/cm2. The key elements for efficient disinfecting are based, on one hand on the exposure time (i.e the ratio between the size of the pond and the flow rate through the filter) , and on the other hand, on the energy emitted in micro watts/second/cm2 at the furthest point from the lamp. Performance is measured in milijoules (mj) by combining the energy emitted by the lamp and the exposure time. The Bio- UV range UV-C lamps work at levels above the minimum required to destroy the principle micro-organisms, which may be found in Koi ponds. In addition thanks to the reflection produced by the stainless steel (316L) within the chamber, efficiency is increased by 20 to 30 %. Micro-organisms must, in theory be exposed for a minimum of 1 second. However, BIO-UV equipment specifications, depending on the flow rates, double the exposure time to 2 seconds, for optimal disinfecting. In order not to hinder the action of the UV-c it is important to have a high filtration quality so that large particles do not screen the radiation. 

Warranties

Bio-UV offers a five-year warranty on the stainless steel chamber and a full year one-year warranty on all other components (including UV lamp).  If installed according to manual.

Finally 

The Bio-UV system gives you the comfort of knowing that your water quality is superior to that of any other type of system, ease of installation, virtually no maintenance and optimum reliability.
