20080230484 | PROCESS FOR TREATING SLUDGE AND MANUFACTURING BIOORGANICALLY-AUGMENTED HIGH NITROGEN-CONTAINING INORGANIC FERTILIZER - The invention describes a new method for treating sludge, which can result in the production of high nitrogen organically-augmented inorganic fertilizer that incorporates municipal sludges or biosolids or organic sludges that can compete with traditional fertilizers such as ammonium phosphate, ammonium sulfate and urea on the commodity fertilizer marketplace. The method takes advantage of the thixotropic property of dewatered biosolids or organic sludge to create a pumpable paste-like material from the biosolids or organic sludge that is then treated with an oxidizer to reduce odorant effects and an acid. This mix is then interacted with concentrated sulfuric and or phosphoric acids and an ammonia source or alternatively a hot or molten melt or salt of ammonium sulfate/phosphate to form a fertilizer mix. The present invention controls the heat, atmospheric pressure and retention time of the fertilizer mix in the reaction vessel. When a fertilizer melt is formed ammoniation is subsequently completed by the specific use of vaporized ammonia. The invention can also be an add-on to commercial production of ammonium salts. The fertilizer produced by the present invention contains more than 8 wt. % nitrogen and preferably 15 wt. % nitrogen. The invention is oriented to be tailored to the biosolids production for individual municipal waste treatment plants in order to keep the fertilizer manufacturing plants of the present invention small with a minimization of logistics and liability. | 09-25-2008 |
20100011823 | Organic recycling with a pipe-cross or tubular reactor - The invention is directed to a process for enhancing the plant nutrient value of relatively low analysis organic waste material (e.g. sewage sludge) involves treating the waste material with an acid and base in a pipe-cross,reactor or tubular to form a melt; spraying the melt onto a recycling bed of fines in a granulator and flashing off the water contained in the melt as steam; rolling the melt onto recycled fine particles in a granulator to form granulated particles; and drying these granulated particles in a to form an enhanced plant nutrient value composition (e.g. a fertilizer or soil conditioner having a greater NPK value than the original relatively low analysis organic waste material). The process further includes drawing off the fumes from the granulator, passing them through a dryer with the granulated particles, and subsequently oxidizing the fumes to eliminate volatile organic compounds and/or gaseous hydrocarbon pollutants be converting such into carbon dioxide and water vapor. | 01-21-2010 |
20100064747 | Sewage Sludge Recycling With A Pipe Cross-Reactor - An improved process for enhancing the plant nutrient value of relatively low analysis organic waste material (e.g., sewage sludge) involves treating the waste material with an acid and base in a pipe-cross reactor. The process more particularly involves mixing the waste material with water to form a slurry (or initially taking the waste material as a slurry); pumping the slurry to a pipe-cross reactor for reaction with a base, acid, and water to form a melt: spraying the melt onto a recycling bed of fines in a granulator and flashing off the water contained in the melt as steam; rolling the melt onto recycled fine particles in a granulator to form granulated particles; and drying these granulated particles to form an enhanced plant nutrient value composition (e.g., a fertilizer or soil conditioner having a greater “NPK” value than the original relatively low analysis organic waste material). The invention also includes fertilizers produced according to the improved process, which fertilizers are of the same size and shape and density of commonly used fertilizers. The method advantageously utilizes the heat generated by the exothermic acid-base reaction in the pipe-cross reactor to remove the approximately 80% water from sludge, thus saving large amounts of energy normally used in conventional drying or burning methods, while, at the same time, conserving the intrinsic values of the nutrients and humates contained in the sludge. In one embodiment, the process includes a method of disposing of spent acid from a hot dip galvanizing process or a steel pickling process involving incorporating the spent acid to maintain the low pH of a venturi scrubber used in the improved process. | 03-18-2010 |
20100288003 | Organic Recycling With Metal Addition - The invention is directed to methods for producing a granular nitrogen fertilizer from an organic material comprising adding a metallic salt to said organic material to form a slurry. Preferably the organic material comprises dewatered biosolids and contains water from a scrubber. Metallic salts that can be used comprise a salt of iron, zinc, or a mixture thereof. Preferred iron salts comprises ferric sulfate or ferric oxide, and preferred zinc salts comprises zinc sulfate or zinc oxide. Preferably, the metallic salt is mixed with an acid such as sulfuric acid to form an acidified metal salt. Slurry pH ranges from approximately 2-2.5. The acidified metal salt is added to the organic material in sufficient quantity to lower viscosity of the slurry such that the resulting fluid does not hinder fluid flow during operation. When the metallic salt comprises acidified ferric sulfate or ferrous sulfate, sufficient iron can be present to produce a fertilizer product with 0.1 weight percent to 10 weight percent iron sulfate calculated on a dry weight basis. The invention is also directed to fertilizer products made by the methods of the invention. Preferred products are granules and the metallic salt increases product hardness. Fertilizer granules preferably contain metal that is bioavailable to a plant when used as a fertilizer. Solubility of the metal of the product in water is enhanced, and the product is low staining. | 11-18-2010 |
20110154873 | BIOORGANICALLY-AUGMENTED HIGH VALUE FERTILIZER - The invention is directed to processes for treating biosolids that result in high-value, nitrogen-containing, slow-release, organically-augmented inorganic fertilizer that are competitive with less valuable or more costly conventional commercially manufactured fertilizers. The process involves conditioning traditional waste-water biosolids and processing the conditioned biosolids continuously in a high throughput manufacturing facility. The exothermic design and closed loop control of the primary reaction vessel decreases significantly the amount of power necessary to run a manufacturing facility. The process utilizes green technologies to facilitate decreased waste and enhanced air quality standards over traditional processing plants. The fertilizer produced from recovered biosolid waste is safe and meets or exceeds the United States Environment Protection Agency (USEPA) Class A and Exceptional Quality standards and is not subject to restrictions or regulations. | 06-30-2011 |

20120247164 | HIGH VALUE ORGANIC-ENHANCED INORGANIC FERTILIZERS - The invention is directed to manufacture of fertilizer having commercial levels of nitrogen supplemented with organic substances. The process treats organic matter with acid causing hydrolysis of organic polymers after which the mix is injected with nitrogen. The resultant sterilized and liquefied organic matter is disbursed over recycled material for the production of granules. Because the process allows for the controlled addition of acids and ammonia, desired levels of components can be achieved. The process is scalable, odor controlled and safe thereby allowing for the location of biosolid processing facilities in most any location. Further, the fertilizer of the invention provides a dual nitrogen-release profile when applied to crops. After application to soil, fertilizer of the invention releases an immediate bolus of nitrogen, similar to traditional ammonium sulfate, followed by continued slow release of nitrogen typically over a season. | 10-04-2012 |
