Ultraviolet Ray Sanitizers
UV Sterilizing
Bacteria or pathogens exposed to high intensity ultraviolet rays in the
germicidal wave length frequency range of 253.7 nanometers are killed.
This level of energy of radiation disrupts the D.N.A. bonding and stops
the bacteria from breeding and consequently the organisms die (bacteria
that can't reproduce are considered dead). UV radiation is extremely
effective in killing micro-organisms such as viruses, bacteria and mould
spores without altering or affecting the water. Some bacteria or viruses
that cling to the pool or spa walls, pipes or filters may not go through
the UV chamber. Water must still be sanitized, disinfected and oxidized
1-3 times per week with 4-5 ppM of unstabilised granular or liquid
chlorine (depending on the load). This eliminates any bacteria or viruses
that have not passed through the UV chamber. The UV light rapidly breaks
down chlorine and in 4 to 8 hours the spa or pool water is free of
chlorine. The best quality of water to soak and relax in. Once you know
how much you need for your application you don't need to test your
chlorine again other than to periodically confirm that you have used
enough chlorine.
Do Not Attempt to use a floating dispenser in conjunction with a
UV chamber as the chlorine or bromine will never reach a high enough
residual level to be effective in killing bacteria on the walls and in the
plumbing.
The UV chamber will just burn off these chemicals as fast as they
dissolve and before you know it your Total
Dissolved Solids will build up to an unrecommended range causing other
problems. All systems chemical free or not, require proper pH levels and
clean filters. This system is a bacteria sterilizer and not a primary
disinfectant. This product is perfect for residential pools and spas. A UV
chamber sells for about $1000 and will give you the least toxic water you
can get and get you very close to chemical free water.
