  • Patent number: 9512046
    Abstract: Phosphatic clays, and the use of phosphatic clays as a soil wetting agent. Phosphatic clays as wetting agents aid in the retention of water in sandy soil, and/or for prevention or reduction of leaching of nutrients. Due to its unique mineralogy, rheology, particle size and shape, phosphatic clay exhibits high water absorbing and retaining qualities as compared to other clay varieties. Further, phosphatic clay is readily available as a by-product of mining of phosphatic ore. The phosphatic clay wetting agents increases the effectiveness of the water applied to the soil, thereby reducing the amount of run-off, and reducing the amount of water needed to accomplish sufficient irrigation. The phosphatic clay wetting agents can be delivered to the soil as a sprinkle-on product, granule product, spray-on product, soil amendment, fertilizer or seed coating, or fertilizer composition.

  • Patent number: 8557013
    Abstract: 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.

  • Patent number: 8491692
    Abstract: A water-dispersible particle is provided that includes organic origin potash in an amount ranging from 5% to 99.9% by weight of the total dry weight of the particle. A binder component is present in an amount from 1% to 95% by weight. The organic origin potash and the binder component on that contact with water causes particle dispersion into more than 100 pieces. A process for making a water-dispersible particle includes mechanical aggregation of the potash into a pellet. A binder component is present in the particle in an amount ranging from 1% to 95% by weight. The potash and the binder component are present in a form such that contact with water causes particle dispersion into more than 100 pieces. The pellet is then dried and ready to be applied.

  • Patent number: 8491693
    Abstract: This invention is directed to systems, devices and methods to beneficiate heat-dried biosolids or sludge pellets or granules as presently manufactured by municipalities or companies from a) dewatered municipal wastewater biosolids or sludges within the municipal wastewater treatment plant heat-dried biosolids production facility or from b) finished dry heat dried biosolids pellets or granules in a separate manufacturing facility from the municipal wastewater treatment plant to produce a fertilizer containing sufficient organic and inorganic plant nutrients to be valuable and saleable into the commercial agricultural industry. The present invention describes beneficiation methods to increase the plant nutrient content of the fertilizer and also to reduce the odors associated with traditionally-produced heat dried biosolids.

  • Patent number: 8470065
    Abstract: The invention describes a new method for the production of high nitrogen organically-augmented inorganic fertilizer that incorporates municipal 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 creates a thixotropic paste-like material from the biosolids or organic sludge that is blended with hot or molten ammonium salts, especially a mixture of ammonium phosphate and ammonium sulfate. The invention can be an add-on to commercial production of ammonium salts or it can stand alone by manufacturing ammonium salts prior to their introduction to the conditioned biosolids. The invention is oriented to be tailored to production facilities for individual municipal waste treatment plants in order to keep manufacturing plants small with a minimization of logistics and liability.
