Systems and methods for biological and chemical gas treatment are disclosed. The systems may generally include a biological treatment zone and a chemical oxidation zone. An oxidizing agent subsystem may deliver an oxidizing agent, such as chlorine dioxide, to the chemical oxidation zone. The oxidizing agent subsystem may generate the oxidizing agent in situ from a product of the biological treatment zone. The oxidizing agent subsystem may include a reaction chamber and a source of a reactant, such as an alkaline metal chlorite reservoir. A controller may be in communication with various sensors and other components to generally manage operation of the disclosed systems.

Gas treatment systems and methods

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.
