FAQs: Water Treatment using UV and Ozone

Thanks to its patented injection system, a regular ozonisation charge* replaces any chemical product, the addition of remanent is no longer necessary (Usually 20-30%) , in contrast to all the other methods of UV or ozone water treatment currently on the market.

• Mode 1 normal : when bathers are present, the device eliminates the ozone before the water leaves the system to prohibit any rejection in the basin.
• Mode 2 shock ozone : when the pool is not used, for example at night, it is the activation of shock ozonization that completely replaces all the residual chemicals.

• The effect combats bacteria, viruses, algae, and fungus.
  
• Ozone kills by oxidation via rupture of the cellular membrane within a few seconds of contact.
  
• The UV has a germ-destroying effect on the micro-organisms which inactivates them (no more reproduction) or kills them.
  
• Having the 2 methods of treatment in the same system means the elimination of all forms of microbiological contamination.

Ozone is nothing more than oxygen to which an additional atom is added.
An oxygen molecule is made up of two atoms. As it passes in front of the UV lamp at 185 Nm, the oxygen molecule (O2) splits into 2 atoms and then reforms with 3 atoms, thus ozone (O3) is created. Ozone (O3) is very unstable and will return very quickly to its original state – Oxygen (O2).

The 2 most common methods are :

1. Using the ultraviolet system (The oxygen is passed in front of a UV-C lamp to 185 Nm).
   
2. Using “corona” discharge (Oxygen is passed over an electric field between two metal plates).

Both means of production are efficient. Here are the main differences :

1. Ozone is injected into the water using a venturi,
2. Water and ozone are mixed in the contact tank
3. The water mixed with ozone passes through two UV tubes with extremely powerful lamps which act to treat the bacteria, virus, fungus, and algae which would have resisted the ozone, and emerges perfectly disinfected.

No, because our “U-B-O” system has a de-ozonisation device, which eliminates the residual ozone in the water before it leaves the system.

Yes, the contact time is sufficient, thanks to the Venturi, the contact tank and the lengthy processing of the ozonated water in our system.

No, disinfectant water is only mandatory for swimming pools open to the public, contrary to the allegations notably spread by some on poorly supervised forums.

Very low doses of the bromine or chlorine pellets is one way of lightly disinfecting water; the quantity used must be at least 0.4 mg/litre, which is 3 times lower than the recommended amount if you treat your water only using bromine or chlorine.

• Use : power consumption of the lamps.
• Maintenance : replacement of the lamps every 10,000 hours for good ozone production, i.e. every 2 to 3 years on average for year-round use of the swimming pool or spa.
  Clean the quartz tubes (Easy to do) every 6 months, depending on the quality of the water.

* 1-4 once a week, at a convenient time when there are no bathers, for example, at night.
