The mineral water is sent to the top of a degassing tower, where it is pulverised into micro-droplets, in order to encourage the gas to separate from the water.
The water then undergoes a vacuum pumping action, to extract the CO2.
The gas removed from this process is stored separately.
The water, which has just had its gas removed, then arrives in a tank where it is mixed with sterile compressed air, before moving to the oxidization tower, where the iron precipitation takes place.
The water is then sent through sand filters which eliminated the solidified iron.
In the last step, during bottling, the water is then re-carbonated with the CO2 extracted during the first step.
More than ten and a half million bottles of water
leave the Orezza factory each year,
after having undergone many controls to guarantee
that the original purity of the water is intact.
