| 141 | Deodorization of livestock waste using ozone | US11230967 | 2005-09-20 | US20070062883A1 | 2007-03-22 | William Frederick; Danny Davis |
| An apparatus for deodorization of livestock waste includes a tank containing livestock waste to be deodorized; a source of atmospheric air; a source of ultraviolet light; and a magnet. Air from the source of atmospheric air is passed by the source of ultraviolet light while simultaneously being exposed to magnetic flux from the magnet, thereby creating a plurality of multivalent oxygen ion allotropes. The apparatus delivers the atmospheric air containing multivalent oxygen ion allotropes to the livestock waste, thereby reducing odor. A method for deodorizing livestock waste, has the steps of: pumping waste from a holding tank; exposing atmospheric air to ultraviolet light and magnetic flux, thereby creating a plurality of multivalent oxygen ion allotropes; exposing the waste to the air containing the plurality of multivalent oxygen ion allotropes; and returning the waste to the holding tank. | ||||||

| Systems and methods for separating manure into a solid fraction and a liquid fraction, and optionally further separating the liquid fraction to capture a sand-rich second solid fraction and a second liquid fraction. Some separators have an adjustable inclination, forcing the manure passage to be slightly up hill, with an overflow box capturing and re-feeding excess manure inflow. One system includes an internally fed rotary screen separator having a perforated outer tube, the perforations being holes less than about 3/16 inch diameter. The outer tube can include spiral inner flights which may be interrupted near the discharge end to allow free fluid to flow back into the separator. The manure can be fed into an inlet conduit having an adjustable angle discharge slot. Some outer tubes have non-perforated end regions serving as the foundation for drive tracks. The solid fraction discharge can be further dewatered in a roller press. Scrape barn, flush barn, sand bedding, straw bedding, and other manure may be handled using these systems and methods. | ||||||

| A method for producing solid fertilizer from liquid manure or from sludge includes mixing the same with harvest leftovers. The liquid substance (manure, sludge) is intimately mixed with the harvest leftovers during grinding. The solids are ground to a particle size of a few microns. The particles adsorb and absorb the liquid substance fully, so that a solid fertilizer product results which neither smells nor endangers the ground water. All of the valuable materials from the liquid substance and from the harvest leftovers are retained in the finished product, which is a high potency fertilizer. The fertilizer can be applied with methods and devices which are conventionally used in agriculture. An apparatus for performing the method includes a grinder/blender which is supplied independently from a harvest leftover storage and from a liquid substance storage. The materials are measured for exact mixture and the pH value may be adjusted. | ||||||

| 159 | Manure separator | US728925 | 1985-04-30 | US4666602A | 1987-05-19 | Kirk Hartzell |
| A manure separator arrangement is described including a flume and chain conveyor arrangement by which initially received slurry of liquids and solids is directed over a perforated flume floor. Liquid is allowed to drain through perforations in the floor as the slurry is moved along a pair of troughs formed along the flume. The entire flume is inclined so the liquids received from the perforated flume floor will drain downwardly away from the solids being carried along by the drag conveyor. Solids leaving a discharge end of the flume may lose approximately 80% of the liquid previously contained in the slurry or mixture. The manure discharged from the flume may be received by a separator press roll mechanism by which remaining moisture can be separated. The separator includes a rotated perforated drum and an oppositely rotated press roll. The press roll is yieldably urged against the rotating surface of the drum and is simultaneously rotated to press or squeeze liquid from the solids. | ||||||
