A method for producing ozone in an ozone generating machine, including the steps of: supplying feed gas containing dioxygen at a gas inlet (O2IN) of an ozone generator (OzG), at a given feed gas flow and feed gas pressure; supplying an alternating electric current so as to create electric discharges to generate a given amount of ozone at a gas outlet (O3OUT) of the ozone generator (OzG); adjusting electric current power and at least one of a plurality of process parameters comprising; characterized in that the method includes, during ozone production, the steps of: monitoring electric power and said at least one parameter of the plurality of process parameters; and adjusting the feed gas pressure in response to the adjustment of the electric current power and said at least one process parameter.

The present invention generally includes an ozone generation system with a power supply that measures the rate of energy delivered to the ozone generation cell. While changing voltage, frequency or current will likely affect the rate of energy delivery, current, frequency and voltage provide a very poor and unreliable control for an ozone generation cell. It is only through control of the rate of energy delivery that consistent, reliable ozone generation is possible. Based upon the measurements of the rate of energy delivery as measured at the ozone generation cell, compared to the rate of energy delivery supplied, the rate of energy delivery supplied can be adjusted to improve ozone production and control.

Method for controlling an ozone generating machine (OGM) comprising the steps of: wherein each base setting file (BSF) is dedicated to a type of ozone generating machine (OGM), retrieving and reading a dedicated base setting file (BSF) corresponding to the type of the ozone generating machine (OGM) indicated by a identification code (ID), encoding and writing a system configuration file (Sysconf) based on the dedicated base setting file (BSF), comprising at least a set of sensor coefficients (SK) and a set of actuator coefficients (AK), producing ozone with the ozone generating machine (OGM), said step comprising at least a step of correcting the at least one sensor signal (SSI) with at least one sensor coefficient (SK) or actuating the at least one actuator (ACT) with the at least one actuator control signal (ACS) corrected by at least one actuator coefficient (AK).

An air scrubber system including a system for creating an oxidation reduction potential (ORP) in water is disclosed. The system includes a pipe assembly for in-line mixing. The pipe assembly includes a first flow path for water to flow through. The first flow path includes one or more ozone intake ports that are fluidically coupled to one or more ozone output ports of an ozone supply unit. The pipe assembly further includes a second flow path fluidically coupled in parallel with the first flow path. The second flow path includes a control valve that selectively permits a portion of the water to flow through the second flow path to produce a negative pressure in the first flow path so that ozone is drawn into the first flow path through the one or more ozone intake ports and mixed into the water flowing through the first flow path.
