Abstract: An ozone water producing system and control method, which is flexibly used indoor or outdoor irrespective condition of a flow channel, is provided for reconstituting polluted water as environmentally friendly. The ozone water generating system is maintained in an optimum state for improving entire performance of the system as well as predicting and preventing the backflow of ozone water, which is occurred due to outlet blocking in a discharging process. The controlling method of the present ozone water producing enables to prevent the deteriorating the performance and ensure the operation stability. The ozone water-producing system comprises an influent air controller, an injector, a gas-liquid separator, and an ozone water-backflow, preventing device. The present system and controller is designed to prevent water backflow, being frequently occurred in the conventional system, for improving the performance, stability and extending operating lifetime.

Abstract: A system for producing ozone water is provided for reproducing the polluted water as environmentally friendly. The ozone water-producing system and its control method in which an ozone water-producing apparatus can be all purposely used indoors or outdoors irrespective of the condition of a flow channel and the condition of ozone generation is maintained in an optimum state so as to improve the performance of the system in its entirety as well as a symptom of the backflow of the ozone water due to a blocking of an outlet in the process of discharging the ozone water is previously detected to prevent deterioration of the system performance and ensure stability in use. The ozone water-producing system comprises influent air control means, an injector, a gas-liquid separator, and an ozone water-backflow preventing means.
