Mechnical Solids Separators set the standard for the removal of solids from farm effluent. Fully automated separation of effluent into liquid and solid factions dramatically improves how the effluent can be stored and handled. Effluent from a feed pad or dairy shed first passes through a stone trap to remove stones and sand. The effluent then flows into a holding tank. Effluent in the holding tank is mixed to provide a uniform consistency and is then pumped up to the solids separator. Excess effluent is by-passed back into the holding tank. The separator removes the solids from the effluent by means of a stainless steel screw press and screen with a screen size as small as 0.25mm. The moist solids fall into a storage bunker awaiting dispersal. The liquid faction flows to a storage tank or holding pond. The liquid in the storage tank or pond can now be pumped out and distributed by almost any type of spray irrigation system. Due to the small size of any solids that may still remain in the liquid effluent it can be distributed by irrigation systems with small nozzle sizes such as centre pivots and K line irrigation systems. Bauer separators stand for reliability as well as a high percentage of dry matter content. Many years of experience, perfected technical design and the use of high quality materials guarantee very long service life and make Bauer the world leader in separator technology Slurry volume reduced by 15 up to 30%.

Liquid Phase

  • This means less storage space and fewer transports
  • Separated slurry does not form floating crusts – therefore it is not necessary to stir the slurry before spreading
  • Due to the extraction of solids and carbon there is less loss of nitrogen (NH3, CH4, N2O) during storage and application
  • Distinctly reduced smell
  • Accurate nutrient analysis possible, therefore, more efficient determination of the time of distribution
  • Low concentration of nutrients, therefore higher rate for application per hectare than with raw slurry
  • Much better infiltration to the soil and less adhesion to the plants ensure that nutrients are more quickly absorbed and crop damage by burning is minimized.
  • Longer distribution period, because head fertilization is possible
  • Easy and low-cost distribution systems
  • Low energy consumption when pumping and conveying
  • Distinctly reduced weed seed content (especially dock) in the liquid fraction.

Solid Phase

  • Self-composting, odor-less and stackable
  • The high content of solids allows storage without any special precautions
  • Improvement of the soil structure and increase of the mold
  • With a dry matter content of 30% and more composting outside is possible
  • Can also be used outside agricultural areas, also for soils where nutrients are needed
  • Easy to transport
  • Recycling as bedding material
