Abstract:
A process for the treatment of water circulating in a conduit, which water carries microorganisms to be eliminated and ions likely to lead to formation of scale on the internal wall of said conduit, comprising:a) measuring at least the flow rate, the temperature and an inlet pH of the water to be treated;b) measuring at least an outlet pH of treated water;c) determining a reference pH from at least one of the parameters measured in step a);d) determining by comparison of the reference pH determined in step c) and of the outlet pH measured in step b), the proportion of gas containing carbon dioxide (CO.sub.2) to be injected into the water to be treated;e) determining a reference ozonation value from at least one of the parameters measured in step a);f) determining, as a function of the reference ozonation value of step e), the proportion of gas containing ozone (O.sub.3) to be injected into the water to be treated; andg) adjusting the pH of the water and eliminating at least one portion of the microorganisms contained in said water, by injecting into the water to be treated a gas containing the ozone determined in step f) and the proportion of gas containing carbon dioxide determining in step d).
