Slurrystore® Processing Systems

Waste Management System – Reap Economic, Environmental Effects

With more stringent environmental regulations, homes moving closer to agricultural operations and groundwater concerns rising, many livestock producers are realizing the economic and environmental benefits of an animal waste management system.

Designed for the proper handling, storage and utilization of livestock manure, a waste management system starts with a Slurrystore. Producers can collect, scrape and/or wash wastes into an above-ground Slurrystore, helping protect the environment and better utilizing wastes as a fertilizer. Engineered Storage Products Company, collaborating with other companies in innovative research, takes pride in helping producers design, improve and implement better animal waste management systems.

Decanting manure helps producers achieve even land application for greater fertilizer efficiency, plus lagoons receiving decanted slurry will be less environmentally hazardous and odorous.

Decanting Manure Before It Enters Lagoon

Decanting – the process of separating nutrients in solids from liquids in slurry before it enters a lagoon – is gaining steam as a few innovative producers and universities are realizing its potential rewards. Lagoons receiving decanted slurry will be less environmentally hazardous and odorous.

By decanting, producers can send the cleanest water possible to the lagoon, reduce odor and lessen environmental contamination in the event of a leak. To tip the scales further, decanting with a Slurrystore means capturing nutrient-rich solids, more consistent nutrient application to fields and a substantial savings in purchased fertilizer costs.

Anaerobic Digesters – Turn Manure Into Energy

Many livestock producers are turning to anaerobic digestion for a safer and more efficient, sustainable way to deal with manure. As we all know, livestock manure has significant resource potential. It is a valuable source of crop nutrients and now manure also represents a substantial bioenergy resource if processed by anaerobic digestion.

Using oxygen-free conditions, an anaerobic digester uses microorganisms to transform waste into biogas, soluble nutrients and additional cell matter, leaving salts and refractory organic matter. Raw biogas typically consists of methane (60%), carbon dioxide (40%), water vapor and trace amounts of hydrogen sulfide. The biogas produced can be converted to electricity or collected and used as a direct energy source. Biogas also can be upgraded and fed into natural gas pipelines. Unlike fossil fuels, use of renewable resources represents a closed carbon cycle and therefore does not contribute to increases in atmospheric concentrations of carbon dioxide. In effect, anaerobic digestion is a carbon dioxide neutral solution.

Anaerobic digestion systems offer significant benefits, providing green energy and helping livestock producers meet increasing environmental regulations.

The largest component of a digester system is the digester tank. Engineered Storage Products Company has been manufacturing and installing glass fused to steel structures since 1949. The company has been designing tanks used in digester systems for more than 25 years. Plus, research has shown that an above-ground mixed reactor, similar to the tanks designed by Engineered Storage Products Company, is very efficient.

Most Engineered Storage Products dealers also can supply reception pit pumps, manure storage structures, manure spreader tanks and solids separators. In addition, authorized dealers can help complete the installation of many of the digester components.

“With a digester, a farm has the potential to fix their energy costs for the next five to six years and, after that, eliminate 95% of the costs for the future. No other waste management option provides this kind of return.”

Nutrient Retention

With rising fertilizer costs, livestock manure is getting to be an even more valuable resource of the plant nutrients nitrogen (N), phosphorus (P) and potassium (K). Adding to its value, manure also can return organic matter and other nutrients, such as sulphur, calcium and magnesium, to the ground, building soil fertility and quality.

The Slurrystore built-in Center Agitation System thoroughly blends and retains nutrients contained in livestock waste.
Only a Slurrystore System is proven to provide ultimate nutrient consistency. With four fully-rotatable floor agitation nozzles available, plus options for over-the-top agitation, Slurrystore Systems uniformly distribute crucial nutrients, creating a homogenized, high-quality natural fertilizer slurry. Other nutrient management systems, such as lagoons and concrete pits, do not adequately agitate the manure. This creates an inconsistent balance of nutrients and produces an uneven fertilizer application.

At the current market rates for N, P and K, the high-quality fertilizer value from a Slurrystore will typically be great enough to pay for the system itself within its first 10 years of use. Call us for more details.

Odor Management

No system can completely eliminate odor. The Slurrystore structure offers engineered solutions to help reduce manure odor problems when compared to other storage methods. In some cases, up to 90% less odor.

  • Smaller surface area (than lagoons or earthen storage pits) exposes less manure to the air.
  • Above-ground design creates a “chimney effect” for lifting odors above ground level.
  • In cattle manure, a natural crust forms on top, sealing in odors.
  • Bottom filling reduces the amount of surface disturbance.
  • An application of straw to the surface area may provide an economical “bio cover”.
