Patent ID: 7204930

Claim:
A system for monitoring and cleaning a groundwater oxidation filtration device, the oxidation filtration device having an aeration section and a filtration section, said system comprising: a. a controller communicating with a sensor, a filtration section discharge port and a filtration section clarification port, b. a filter rate corresponding to a filter pressure and a filter period, a discharge rate corresponding to a discharge pressure and a discharge period, clarification rate corresponding to a clarification pressure and a clarification period, c. the sensor sending to the controller a discharge signal to open the filtration section discharge port after reading the one or more of the following: i. a decrease in the filter rate, ii. an increase in the filter pressure, iii. an end to the filter period, d. the sensor signaling the controller to close the filtration section discharge port and open the filtration section clarification port after reading one or more of the following: i. a decrease in the discharge rate, ii. a decrease in the discharge pressure, iii. an end to the discharge period, e. the sensor signaling the controller to close the filtration section clarification port and resume filtration after reading one or more of the following: i. a decrease in the clarification rate, ii. a decrease in the clarification pressure, iii. an end to the clarification period.
