Abstract: An alcoholic beverage, such as rum, is aged in a non permeable metal container containing suspended wooden staves. During the aging process oxygen is injected into the aging beverage, so as to maintain a preselected dissolved oxygen concentration in the beverage, preferably in the range of 7.25 and 8.2 milligrams of oxygen per liter of beverage.
Abstract: An apparatus is provided for treatment of organic contaminant containing waste water such that the oxygen demand of the waste water is reduced and methane is produced. The apparatus comprises an anaerobic digester or filter. The digester is packed with a media which provides a substantial growth surface area to microorganisms contained within the digester. The digester also includes recirculation means whereby fluid in the digester below the media is recirculated directly to an upper portion of the digester. Furthermore, the digester has effluent overflow outlets which outlets include a trap to prevent oxygen from entering the digester from the atmosphere. Fluid to be treated in the digester enters the upper portion thereof, passes downwardly through the media, is recirculated by the recirculating means to an upper portion of the digester, and exits the digester after treatment by the microorganisms therein through the outlets.

Abstract: A method is provided for reducing the oxygen demand of waste water having a partial organic composition, especially a solution commonly known as mostos which is the waste effluent of a molasses fermentation and distillation process. The waste water is fed into an anaerobic digester near the top thereof so as to flow downwardly through the interior of the digester. The digester is at least partially filled with a high surface area media. The digester contains a microorganism which preferentially produces methane when in contact with the organic material in the waste water and also reduces the oxygen demand of materials therein. Also preferentially, the microorganisms tend to grow on the media surface. Nitrogen and phosphorous containing materials are added as necessary to promote growth of the microorganisms. As the waste water flows downwardly through the digester, methane is released therefrom which bubbles to the surface whereupon the methane is collected for combusting to produce energy.
