Definitions

  • Animal excrement is a chemical complex of biologically active material which is discharged by animals because their digestive systems do not efficiently utilize all components of their food intake. Depending on the structure of the animal's digestive system and its efficiency, the composition of excrement changes. The type and variety of food intake also affects the composition of the animal's excrement.
  • manures which are chemical complexes, do not contain balanced nutrient components. Relative to a plant's demand for nitrogen, for example, most manures have an excess of phosphorus and potassium. These factors affect the efficient use of the material in agriculture. In particular, high phosphorus can damage aquifers through percolation, and affect rivers and lakes through runoff from the land that causes
  • eutrophication During storm events, overflow or breach of holding ponds releases pathogens and/or parasites resident in the manures including, for example, E.coli and helminths, a situation that can be further complicated by the routine use of antibiotics in the animal feed.
  • pathogens and/or parasites resident in the manures including, for example, E.coli and helminths, a situation that can be further complicated by the routine use of antibiotics in the animal feed.
  • Another practical problem associated with manures is the undesirable odor they typically emit. Such odors can range from highly organic in the case of swine to highly ammoniac in the case of chickens.
  • the present application discloses a process for the production of a high efficiency organic fertilizer derived from animal manure, such as livestock and/or poultry manure. While the process may be exemplified herein in places using a description of a swine manure treatment, the process is also quite suitable for the treatment of other animal manure streams, e.g., other livestock manures and/or poultry manures, such as chicken or turkey manure streams.
  • the process may accomplish one or more of the following objectives:
  • the present process includes adding an oxidizing composition to a slurry of animal manure and processing the slurry of oxidizing composition and animal manure in a device configured for inducing cavitation within the slurry.
  • a cavitation unit such as the one depicted in Figures 2 and 3.
  • the slurry of oxidizing composition and animal manure may be passed through an inline mixer before the cavitation operation in order to ensure that the slurry has a relatively homogenous composition and/or the particles in the slurry are well suspended during the cavitation operation.
  • the process may be operated in a batch mode, but for larger scale operations it is typically advantageous to operate the process in a continuous mode, e.g., where the slurry of oxidizing composition and animal manure is continuously circulated through a loop containing the inline mixer and cavitation device and oxidized slurry is removed from the top of a mixing tank using an overflow outlet.
  • the process may also include adding a humus based materials, either in the form of a humus-based complex (e.g., containing about 60-65 wt.% organic material which the remainder mineral) and/or a dry humus material.
  • a high calcium binding agent e.g., gypsum and/or lime
  • the product may be pelletized using conventional pelletizing technology.
  • the nutrient content of the final product may be adjusted as desired by adding other nutrient materials (e.g., N-P-K sources and/or trace mineral sources) to the materials being processed.
  • the cavitation units described in the present application can also be used as part of a method to treat other pathogen containing aqueous streams, which may or may not also includes particulate materials, e.g., aqueous streams which contain substantial amounts of undesired biological material such as algae, bacteria or other undesired pathogens.
  • An oxidizing composition which optionally contains surfactant, is added to the contaminated aqueous stream, which is then passed through a cavitation unit, such as the one described herein.
  • the product stream may be treated to remove debris from the pathogenic material, e.g., by addition of a flocculating agent (such as a polymeric flocculating agent) and subsequent filtration.

  • Commercial swine waste typically comprises an average of 3 to 4 wt% solids, in some case higher, with the balance being water.
  • Other livestock or poultry manure streams to be treated may have solids contents of up to about 25 - 30 wt.%.
  • the majority of solids in animal manures are organic materials such as fat, protein, and cellulose. Total mineral content is normally less than 1 wt%.
  • the result of this combination of material is a complex of organic matter that is highly active, and which continuously generates sulfur, ammonia, and organic odors. It is an excellent growth medium for bacteria and pathogens commonly found in the animal digestive tract.
  • the complex is generally also an excellent habitat for parasitic worms such as helminths, insects, and other undesirable microfauna.
  • Manure also contains small amounts, 1 to 2 wt%, of straw which has been added to control the release of odors.
  • Manure may exist in several forms, e.g., swine manure commonly exists as a slurry produced by water periodically added to the swine pens to clean them. Cattle manure is often a drier solid form due to exposure to air in feedlots.
  • N-P-K Nitrogen-Phosphorus-Potassium
  • the raw animal manure is commonly processed to remove all larger particles, e.g., particles > about 0.5 inches in size, from the slurry by, for example, a conventional screening process. This oversize material may then be set aside for additional processing for topical odor control and subsequent composting.
  • the screened slurry may contain up to about 25 wt% solids, often about 5 to 20 wt%. Slurries having a solids content of about 10 to 15 wt% are quite suitable for treatment using the present process. As noted below, when the process is used to treat swine manure, the slurry may only have a solids content in the 3 to 5 wt% range.
  • the screened slurry is then typically processed to form a stabilized, generally homogeneous slurry that has been treated to kill or neutralize the majority of the parasites and/or pathogens present in the raw manure. This may be done with a combination of physical and chemical means. From the screening process, the screened slurry may be pumped to a mixing tank, where it is commonly combined with an oxidizing composition, which has an odor suppressing effect as well as helping to neutralize the parasites and/or pathogens which are commonly present.
  • the mixer in the tank may be operated at a relatively low speed, for example, 20 to 50 rpm.
  • the oxidizing composition typically contains an oxidant, such as a percarbonate salt, hydrogen peroxide, sodium perborate, sodium hypochlorite or other peroxide material (e.g., organic peroxides, such as an organic percarboxylic acid, e.g., peracetic acid).
  • the oxidizing composition may also contain a surfactant that is stable in the presence of the oxidant.
  • the oxidizing composition may include a fatty acyl sarcosinate salt and/or a fatty acid salt.
  • the screened slurry may be treated with ozone for odor suppression and oxidizing purposes.
  • a suitable oxidizing composition useful for the present process includes a mixture of sodium percarbonate, sodium lauroyl sarcosinate and sodium laurate.
  • the oxidizing composition may contain 30 to 60 wt% sodium percarbonate, 35 to 45 wt% sodium lauroyl sarcosinate, and 1 to 5 wt% sodium laurate.
  • Oxidizing compositions such as those described above may be blended into the screened slurry at a weight ratio of about 1 : 1000 to 1 :4000 (oxidizing composition: screened slurry). Variations in the composition and the desired degree of odor suppression may require other feed rates.

  • the slurry is processed though a device configured for inducing cavitation within the slurry.
  • a device configured for inducing cavitation within the slurry.
  • bubbles are created that instantaneously implode.
  • the implosion creates momentarily high temperatures, which, in combination with the hydroxyl radicals formed in the treated slurry through the action of the additive composition noted above, increase the rate of oxidization of remaining pathogens.
  • An additional function of the cavitation is to break the unstable material in the slurry that creates gas containing undesirable odors.
  • the slurry is commonly re-circulated through the mixing tank, in-line mixer, and cavitation device, often for approximately 5 to 10 minutes.
  • the slurry is continuously recirculated through the mixing tank, in-line mixer, and cavitation device, while oxidized material is removed from the mixing tank, e.g., via an overflow port.
  • the mixing tank may be so constructed that an overflow port feeds the oxidized slurry into the downstream equipment.
  • FIG. 2 One embodiment of a cavitation device configured for inducing cavitation within the slurry suitable for use in the present method is depicted in Figure 2.
  • Figure 3 is depicts one example of a cavitation processor unit within the cavitation unit, which also typically includes a downstream vibration damper.
  • the cavitation unit may be operated in a mode (as illustrated in Figure 2) such that a substantial portion of the slurry being treated is recirculated one or more times through the cavitation processor unit.
  • the relative flows may be adjusted so that only about 5 to 20 percent of the volume of treated slurry passing through the processor unit is removed via the processor unit unit outlet with the remainder being recirculated through the recycle loop.

  • flow through would occur from left to right through the processor unit depicted in Figure 3.
  • the unit is typically operated such that the back pressure of the inflow to the cavitation processor unit is at least about 80 psi, with back pressure of about 85-90 psi being quite common. While in operation, the cavitation induced in the cavitation processor unit can be adjusted by varying the flow rate into the processor unit - increasing the flow rate will have the effect of increasing the back pressure on the incoming slurry.
  • the oxidized slurry may then be introduced into a mixing tank and agitated with a high-speed mixer operating at, for example, up to 500 rpm (e.g., at 100 to 300 rpm, with mixing speeds of about 200 rpm being common). This helps to homogenize the slurry and tends to keep the very small particles in suspension.
  • the oxidized slurry is often combined with a humus-based complex at, for example, a weight ratio of 1 : 1000 (humus-based complex : oxidized slurry) for production of liquid fertilizer or, for example, a weight ratio of 1 :2000 for the production of solid fertilizer.
  • the humus-based complex typically includes, for example, humic acid, fulvic acid, short chain protein(s), glucose or sorbitol based surfactant(s), vegetable oil(s), and/or trace elements, e.g., trace elements derived from seaweed.
  • the oxidized slurry may be mixed with the humus-based complex for 1 to 15 minutes, with roughly 10 minutes typically being sufficient to achieve substantially complete homogenization.

  • a dry humus material e.g., dry humus material derived from naturally occurring lignite and/or leonardite.
  • the result of mixing for about 20 to 60 minutes (30 minutes preferred) is the creation of a substantially thickened composition, which is desirably characterized by a consistency similar to that of thick syrup.
  • the thickened composition resulting from the processing described above may then be pumped to another mixing device, such as a paddle mixer, for successive chemical input(s).
  • a paddle mixer is desirable in order to create the correct consistency for subsequent processing and to avoid the feed stock sticking together and forming balls of feed stock that may not as readily be incorporated with the materials being added during this step.
  • a gypsum/quicklime mixture is commonly added in order to reduce moisture content and to further suppress or destroy any remaining pathogens by heating the composition to a temperature between about 150°F and 180°F, with temperatures of about 150°F to 160°F commonly being achieved.
  • the amount of gypsum/quicklime mixture employed is typically between 1% - 25 wt% of the composition (typically about 15 to 25 wt.%, often about 2o wt.%).
  • the gypsum/quicklime mixture may include about 1 to 30 wt% gypsum (commonly about 10 wt%) and about 70 to 99 wt% quicklime (commonly about 90 wt%).
  • water e.g., about 0.25 to 0.5 wt% may be added to the partially dried composition depending on whether sufficient moisture is contained in the initial stage to fully activate the quicklime.
  • the additional water reacts with the residual quicklime in an exothermic reaction which can facilitate maintaining the temperature of the slurry at at least about 150°F and in some embodiments at about 160°F to 180°F. This elevated temperature is intended to kill or suppress any pathogens that survived the previous oxidation and cavitation steps detailed above.
  • the N-P-K content of the mixture may be adjusted to meet the desired specifications of the final product. Because the initial N-P-K of the raw manure is very low, and because the mixture is now predominantly solid particles, any selected amount or combination of N, P, and K sources can be added to the composition to achieve a desired composition. If desired, wholly natural organic ingredients may be used if the fertilizer is to be certified Organic in accordance with the National Organic Program of the U.S.
  • blood meal dried animal blood
  • bone meal hydrolyzed bone
  • K2S04 non-synthetic potassium sulfate
  • N, P, and K sources can be used, for example, ammonium nitrate (NH4N03) may be the source of nitrogen, dipotassium phosphate (K2HP04) may be the source of phosphorus, and synthetic potassium sulfate (K2S04) may be the source of potassium.
  • ammonium nitrate (NH4N03) may be the source of nitrogen
  • dipotassium phosphate (K2HP04) may be the source of phosphorus
  • K2S04 synthetic potassium sulfate
  • the composition of the organic fertilizer is generally complete.
  • the now dry product may be pelletizes, e.g., by extruding the dry product through a pelletizer sized to produce fertilizer pellets of a designated size, e.g., approximately 0.125" diameter pellets. Other sizes may be used if desired, but 0.125" gives a product generally compatible with conventional fertilizer spreading equipment and agricultural practices.
  • the product is commonly dry to the touch.
  • the organic fertilizer pellets may be moved by conveyor belt through a radiant heat dryer.
  • Infrared heat is preferred, which can have the beneficial effect of eliminating any residual pathogens that may have escaped previous destruction steps.
  • Other forms of radiant heat can also be used with the purpose of reducing the moisture content of the pellets to less than 2 to 5 wt% (3 wt% being common). After drying, the organic fertilizer is complete and the product is ready for packaging.
  • pathogens may still exist in the fertilizer feed stock. These pathogens may be subjected to additional processing to destroy or neutralize them including, for example: Adding calcium, magnesium, and/or potassium oxide, or alternatively sulfur gas, to a mixing tank operated at 20 to 50 rpm, with a dwell time of 15 to 45 minutes (30 minutes preferred). This method is preferred because of its relatively low cost and relative safety.
  • an ozone oxidation unit may be used to destroy the remaining pathogens. This unit would be injected with ozone at a rate of 0.1 to 1.0 pounds per ton (0.8 pounds per ton preferred). Ozone, however, is less preferred due to the expense of the oxidation unit and also because ozone requiries special handling precautions and thus increased expense.
  • the treated fertilizer feed stock is pumped to the last mixing tank operating at a speed of 20 to 50 rpm where it resides for 1/2 to 1 hour.
  • the N-P-K values are adjusted to the desired levels up to, for example, a maximum of 10-10-10 using either organic N, 13, and K or synthetic N, P, or K depending on whether the product will be certified Organic or not. This is performed using the chemicals and/or compositions described above. Production of the liquid fertilizer product is now finished and it can be packaged as desired.
  • the desire to maximize the production of livestock and poultry at a minimum cost has created vast quantities of manure which are an environmental hazard, but also represents a resource that can sustainably and economically be converted to either a certified organic on non-certified fertilizer.
  • the product may have one or more of the following the following advantages:
  • the ratio of the main nutrient elements is better balanced for improved plant uptake.
  • the mobility of the nutrient elements after application to the soil is controlled through a buffering or controlled release provided by the humus-based complex that modulates the absorption and transfer of nutrients to the soil so that the fertilizer does not wash away after the first rain.
  • the organic structure provided in the fertilizer controls the cation and anion exchange in the soil so that the release of nutrients is gradual.
  • Synthetic fertilizers for example, can lose up to 70% of their nutrients to runoff, while fertilizers with substantial organic components may retain up to 90% of N-P-K in the soil. The result is that much less fertilizer containing organic components is required for a given crop than for a conventional fertilizer using synthetic N-P-K.
  • the solid form of the fertilizer can be applied using existing commercial fertilizer spreading equipment.
  • the organic structure in the fertilizer affects the heat exchange capacity of the soil so that a lower temperature is maintained during daylight, and a higher temperature is maintained at night. This attribute is particularly important in areas with elevated daytime temperatures and cold nights such as dry desert environments. The net result is reduced stress on the plant.
  • the fertilizer typically contains numerous trace elements required for healthy plant life. These are normally not present in commercial synthetic fertilizers. Finally, the additional organic matter provided in the fertilizer may increase the level of biological activity in the soil, thus increasing the soil's resistance to granulation and dissipation by runoff and/or wind.
