A variety of treatment techniques are available for aboveground treatment and include thermal destruction (e.g., direct flame thermal oxidation, catalytic oxidizers), adsorption (e.g., granular activated carbon, zeolites, polymers), biofiltration, non-thermal plasma destruction, photolytic/photocatalytic destruction, membrane separation, gas absorption, and vapor condensation. The most commonly applied aboveground treatment technologies are thermal oxidation and granular activated carbon adsorption.
A variety of approaches are available for treating contaminants in the air above ground, including thermal incineration (e.g., direct flame thermal oxidation, catalytic oxidizers), absorption (e.g., granular activated carbon, zeolites, polymers), biological treatment, non-thermal plasma destruction, photolytic/photocatalytic treatment, membrane separation, gas absorption, and vapor condensation. The most commonly used aboveground treatment technologies are thermal oxidation and granular activated carbon adsorption.
