A self-regenerating bio-gas treatment system that uses the bio-gas instead of atmospheric are as media transport between adsorber and desorber tanks. Each tank includes at least four horizontally stacked and evenly spaced apart, perforated trays each capable being filled with fluidized carbon which migrates downward in the adsorber tank to remove contaminants from the bio-gas. With the bio-gas function as its media transport, the carbon media continuously moves downward over the perforated trays and eventually collected in the bottom of the adsorber tank. The spent carbon is then delivered to the desorber tank. The desorber tank is filled with an inert gas produced by an inert gas generator which causes the carbon media to be regenerated. The inert gas strips the carbon media of contaminates and is then delivered to a ground flare. The carbon media is returned to the adsorber tank and re-used to treat bio-gas. A plurality of heat exchangers, blowers, valves and interconnecting conduits keep the bio-gas, the inert gas, and the carbon media continuously flowing through the system thereby enabling the system to be used at different sizes of landfills or treatment plants.
