An apparatus for anaerobically treating waste to allow the waste to be safely disposed of and/or to reclaim useful gas therefrom. The apparatus includes a tank, a cylinder positioned within the tank to divide the tank into first and second areas, and media such as stones or the like positioned within the first and second areas of the tank for supporting anaerobic bacteria growth. Liquid waste is introduced into the first area of the tank over the media therein. As the waste flows through the media, the waste will be partially treated and methane gas or nitrogen gas will be formed or reclaimed therefrom. As more waste is introduced into the first area of the tank over the media therein, waste that has passed through the media in the first area will be forced upward through the media in the second area where it is further treated. Waste that has passed upwardly through the media in the second area of the tank is removed from the apparatus. The bottom edge of the cylinder is flared outwardly and downwardly to direct any gas formed when the waste passes through the media in the first area of the tank back upwardly through the media in the first area of the tank. After such gas passes upwardly through the media in the first area of the tank, it can be collected or it can be allowed to pass to the atmosphere.
