ABSTRACT:
A system and method for the purification and biodeodorizing of a gas are disclosed. The system is highly adaptable and capable of operating in a variety of modes to tailor performance of the system to specific odor control applications. The scrubber stages of the system may each be maintained at different conditions to selectively promote bacterial activity that targets a variety of odorous constituents. The pH level of the irrigation fluid provided to each scrubber stage may be controlled.
