Abstract:
1. An ozone gas supply system, comprising: a plurality of nitrogen-free ozone generation units, an ozone gas output flow rate management unit, and an ozone gas output flow rate management unit control part, wherein the ozone gas supply system is configured to supply an ozone gas to each of a plurality of ozone treatment apparatuses while controlling a flow rate and concentration of the ozone gas, each of the plurality of nitrogen-free ozone generation units comprises: the ozone gas output flow rate management unit is configured to receive a plurality of ozone gas outputs from a plurality of the nitrogen-free ozone generators in the plurality of nitrogen-free ozone generation units, and is capable of performing an ozone gas output flow rate control, thereby selectively outputting one or a combination of two or more ozone gas outputs to any of the plurality of ozone treatment apparatuses by opening or closing any of a plurality of ozone gas control valves in the ozone gas output flow rate management unit, and the ozone gas output flow rate management unit control part is suitable for, based on a process ozone gas event signal from the plurality of ozone treatment apparatuses, controlling ozone gas output of each of the plurality of nitrogen-free ozone generation units and causing the ozone gas output flow rate management unit to control ozone gas output flow rate.
