Abstract
A method and apparatus are provided for minimizing the emissions of odorous gases and fatty acids generated by digestible and odiferous waste. The apparatus includes a treatment comprising oil, activated carbon and a base buffering agent. The apparatus also includes a system for delivering the treatment through a low pressure output, such as a low pressure manifold with a plurality of delivery pipes. A starter plank made of concrete, used for mounting the apparatus on a wall and a flotation board, made of foamed polystyrene board, directs the flow of the treatment onto the surface of the waste. The method includes the steps of applying oil and activated carbon to the surface of liquid waste and injecting a base buffering agent below the surface of the oil/activated carbon layer. The oil and activated carbon create a seal that prevents odorous emissions from entering the air space above the liquid waste and the base buffering system neutralizes the acidic waste.
