Abstract:
Process for the preparation and delivery of ozonated water to at least one user point, comprising the steps of:a) providing a storage buffer tank for the ozonated water; b) providing an upstream ozonation loop, making it possible to supply the tank with ozonated water, for which: the tank is integrated into the loop; the upstream ozonation loop comprises a gas/liquid transfer component and a component for controlling the flow of water flowing in the loop; providing an ozonated-gas supply line, linked by its downstream part to the transfer component and by its upstream part to an ozonator; providing a fresh-water supply line, connected by its downstream part to the upstream ozonation loop and fitted with a component for interrupting the fresh-water flow; fitting the loop portion located between the tank and the connection point of the fresh-water supply line with a component for interrupting a recirculation flow upstream of the tank; c) providing a line for feeding said at least one user point with ozonated water from the tank; d) controlling the tank fill level between a low level N1 and a high level Nh using said component for controlling the flow of water flowing in the ozonation loop, one or other of said component for interrupting the fresh-water input and said component for interrupting the recirculation flow upstream of the tank being always open while the other of said components is closed.
