Abstract: A method is provided for minimizing the emissions of odorous gases and neutralizing volatile fatty acids generated by anaerobic decomposition of digestible and odiferous animal waste that includes the step of adding an alkaline solution to the digestible and odiferous animal waste to at least partially neutralize volatile fatty acids present in the digestible and odiferous animal waste and applying a layer of oil and activated carbon to the surface of the waste. A system for applying the above method includes means for applying the layer of oil and activated carbon to a surface of the waste; means for injecting the alkaline solution into the waste below the layer of oil and activated carbon; means for monitoring the pH level of the waste; and means for triggering the injection of additional alkaline solution when the pH level of the waste reaches a set point.

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.
