What are UV-C rays and how they works
The small part of electro-magnetic spectrum having wave lenghts included between 100 and 400 nm (thousandths of micron) is
defined as space of the ultra-violet irradiation.The UV-C are part of the subspace characterized by the wave lenghts included between
100 and 280 nm.
For being effective in the disinfection, an electro-magnetic wave, besides being of a certain kind (L= 254 nm) it must possess also a
minimum value of intensity to be able to ensure a minimum dose to water.
A uv sterilizer, if correctly sized, is able to give water a dose sufficient for reducing almost all the commonest micro-organisms
present in water.
Applications
The uv systems can be used:
– with well water (it is recommended to do a water analysis to know the kind and the quantity of the bacterial count)
– residential use with reverse osmosis system and microfiltration
– industrial use with laboratories, aquarium, swimming pool units
Benefits
-uvc acts instantly (without any stocking tank like in the chlorination system)
– compatibility with the other technologies (filtration, reverse osmosis, softening…)
– environmental treatment (without addition of chemicals)
– no alteration of the taste of water
– praticticality (is required only a power outlet)
– cheap and with little required servicing (the uv lamp must be replaced once a year)

– Clip included with the uv lamp system
Which are the factors that can be influnce the right operation of the lamp
– The water hardness
– iron
– sediments in the water
For this reason it is necessary…
– water softener to redure the water hardness
– water systems to reduce iron in the water
…and we recommend always the installation of:
– an housing with a reeled polypropylene cartridge before the uv system to protect it
