  • Patent number: 10450202
    Abstract: There is provided herein a system and method for de-toxifing and de-scaling source water. In some embodiments, source water will be mixed with either an aluminum source or an iron source to separate endotoxins from acidic proteins and convert the naturally present bicarbonate in source water to carbon dioxide. Endotoxins and carbon dioxide will then be removed from source water by a stage of hydrophobic membranes to produce de-toxified and de-carbonated source water. Magnesium hydroxide will be mixed with the de-toxified and de-carbonated source water to form precipitates comprising foulants and sulfate. A recoverable and reusable amine solvent will also be used to induce efficient precipitation. Possible reuse applications for the treated source water by the inventive methods that minimize excessive uses of potable water may include hydro-fracturing of shale and sand formations and heavy oil recovery by steam injection.

  • Patent number: 8992654
    Abstract: 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.

    Abstract: Hydrophobic contaminants are removed from sludge that has been liquidized by violent shearing, by stirring a hydrophobic sorbent substance material into the sludge. After a period of time in which the contaminants are sorbed into the sorbent, the sorbent substance is separated from the sludge by gravity-settling, centrifuging, etc, where the sorbent is a liquid, or by filtration etc where the sorbent is a solid. Some sorbents have a melting point such that the sorbent can be liquid for good dispersal in heated sludge, and then can be solid when the sludge has cooled, whereby the sorbent can be removed e.g by filtration. Liquefaction by violent shearing causes the biosolids in the sludge to go into solution, which leaves the hydrophobic contaminants more available to be sorbed.

  • Publication number: 20130213101
    Abstract: The invention provides for methods, devices, and systems for pyrolyzing biomass. A pyrolysis unit can be used for the pyrolysis of biomass to form gas, liquid, and solid products. The biomass materials can be selected such that an enhanced biochar is formed after pyrolysis. The biomass can be pyrolyzed under specified conditions such that a selected biochar core is formed. The pyrolysis process can form a stable biochar core that is inert and/or resistant to degradation. The biochar or biochar core can be functionalized to form a functionalized biochar or functionalized biochar core. Functionalization can include post-pyrolysis treatments such as supplementation with microbes or physical transformations including annealing and/or activation.

  • Publication number: 20130180299
    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.

  • Patent number: 8460426
    Abstract: A method and system for treatment of biological wastes for preparation of fertilizers is provided. The method and system involves mixing a biological waste with a dilute sulfuric acid in a predetermined ratio. The mixture of the biological waste and the dilute sulfuric acid is then filtered to obtain an organic slurry and an acidic liquid. Thereafter, the organic slurry is thermally cracked at an elevated temperature to obtain at least one of an ammonia gas, one or more flue gases, and char and ash. The method and system further involves utilizing the ammonia gas, the char and ash, and the acidic liquid for preparation of the fertilizers.

    Abstract: A particle is provided that includes 5 wt % to 90 wt % of agricultural biomass, combustion residues, biosolids, or a combination thereof. A binder intermixed with the agricultural biomass, combustion residues, biosolids, or a combination thereof retains the mixture in the form of a particle. The resultant particle creates a use for existing waste streams while also improving soil quality. A process of stabilizing agricultural biomass, combustion residues, biosolids, or a combination thereof particles is also provided that includes combining agricultural biomass, combustion residues, biosolids, or a combination thereof with mineral and/or synthetic chemical fragments having a bulk density of greater than about 40 pounds per cubic foot and a sizing of about 100% passing through a 30 mesh screen and about 50% or more passing through a 200 mesh screen. By adding binder, a particle is formed that is deodorized and/or stabilized.

    Abstract: The method of making an acid-absorbing biosolid composition provides a method for the use of recycled materials to produce an acid-absorbing composition that may then be recycled as a fertilizer after absorbing the acid. The method includes the steps of: collecting sewage sludge; drying the sewage sludge to remove water therefrom to form dried sludge; adding hydrochloric acid to the dried sludge to form a liquid intermediary product; heating the liquid intermediary product to produce a dried porous biomass; and mixing inorganic waste material with the dried porous biomass to produce the acid-absorbing biosolid composition. Thereafter, the acid-absorbing biosolid composition may be placed in a gas flow to absorb an acidic component therefrom; and then recycled for use as fertilizer following absorption of the acidic component from the gas flow.

    Abstract: Paunch-sludge from an abattoir is mixed with the fatty DAF-float from an abattoir, and placed in a shearing vessel. The mixture of the two material thickens the medium in which the matted strands are contained, enabling shearing to be more effective; so much so that paunch-sludge can now be sheared to a homogeneous liquid. The technique can be used with other sludges and other fatty waste materials.
