Without chlorine

Swiming pool treatment

Bathing in pure, healthy, natural, 100% organic water.

* The principle of the patent includes 2 modes of operation:

  • 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 ozone shock : when the pool is not used, for example at night, it is the activation of shock ozonization that completely replaces all the residual chemicals.

Attention: circulation pump, filter, pH / ORP regulation, heaters, etc. are not included in the bacteriological treatment system.
