UV HOME 4 – 4.6 m³/h

BIO-UV Group, the ultraviolet water treatment specialist for 20 years, developed a concept for chlorine-free water treatment based on disinfection technology using type C ultraviolet light. The BIO-UV reactors in the UV HOME and IBP ranges are used to make raw water coming  from local drinkable resources, water in the system safe to drink, particularly after dechlorination using active charcoal and recycled rainwater safe for domestic use only.

Principle / Action

The sun emits an invisible light known as ultraviolet rays. This natural phenomenon is reproduced within BIO-UV Group’s light chambers, using powerful lights incorporating the latest technology that emit UV-C rays. 254 nanometers is the optimum wavelength for inactivating micro-organisms (viruses, bacteria, algae, yeasts, mold); UV-C light penetrates to the heart of the micro-organisms’ DNA and disturbs the metabolism of the cells. All the germs are thus inactivated (including legionella and cryptosporidium) and can no longer reproduce. Concerning the removal of chloramines special UV-C lamps are designed to produce a larger variety of lightwaves that are more effective at irradicating tri-chloramines which are known to cause respiratory ailments. The UV dose is equivalent to the UV energy that the living micro-organism has to absorb to be inactivated. The table below shows the UV-C dose levels (expressed in millijoules (mJ) /cm2) required to eradicate 99.9% of the micro-organisms.

Benefits
