An improved system and method for controlling ozone concentration in connection with a multi-chamber tool. The system and method involve a first and a second concentration controller in combination with an ozone generator. The first concentration controller detects an EVENT (i.e., one of the chambers in the multi-chamber tool coming on-line or off-line) and in response provides a power instruction to the ozone generator in accordance with a predictive control algorithm. The first concentration controller has a fast (i.e, about 1 second) response time. The second concentration controller is masked from the ozone generator during the EVENT, but otherwise controls the generator after an interval of time has lapsed after the EVENT. The second concentration controller has a slower response time than the first concentration controller, however the second concentration controller provides the system with long-term stability and can be used to provide updated data to the predictive control algorithm.

The technique consists of a BAF pond, an air-bearing system, an ozone contact oxidation tower, a filter, an active carbon filter, an ozone generator and a medicine adding system. The technique is the improvement of the traditional BAF technique, removes the resolvable organism in the sewage through the biological degradation, outtakes the water into the air-bearing system and combines the flocculation medicine adding technique, so as to eliminate the non-solvent organism and colloidal substance in the sewage. The outtaken water enters into the ozone contact oxidation tower and gets mixed with ozone, so that the organism which is difficult to undergo the biological degradation in the printing and dyeing sewage is removed with the help of the strong oxidizing property of the ozone.
