10 PTH irrigation pump with double chopping system.

Why separate the liquid manure into two fractions, solid and liquid?

Benefits from the solid fraction

  • Use as compost in greenhouses, orchards, etc.
  • Use in the fields prior to sowing since the Nitrogen, present in organic form in the solid fraction, is slowly absorbed by the soil.
  • Reduced methane and odour emissions thanks to aerobic stabilization of the solid fraction.
  • Use as livestock bedding.
  • Easy and economical to transport.

Benefits from the liquid fraction

  • Use for flushing out waterways and canals.
  • Use for fertigation in the fields.
  • Reduced volume of the lagoon used for storing the liquid fraction thanks to the absence of the solid fraction.
  • Use in the fields during plant growth since the Nitrogen, present in ammoniacal form in the liquid fraction, is rapidly absorbed by the soil.
  • Reduced Ammonia NH3 emissions since the liquid fraction penetrates rapidly into the soil.
  • Use in nitrogen removal plants.
