Abstract
Method for making of solid fertilizer by separation of liquid manure into a solid and a liquid phase by means of a separating vessel, wherein the charged liquid manure at first is divided into a solid layer and into a liquid phase and from where the liquid phase is fed into a collector vessel, and whereby the solid phase is separated. The duration time of the liquid manure in its resting stage is delayed until the layer formed by the solid phase is separated on the top of the vessel and then the discharge of the liquid phase is carried out through closeable openings.
Claims5
In a method of making a solid fertilizer by separation of liquid manure into a solid phase and a liquid phase by means of a filter vessel into which the liquid manure is charged, said filter vessel having a bottom and a top and at least one closeable discharge opening, the improvement comprising the steps of immersing the bottom of the filter vessel into a liquid;
- then introducing the liquid manure into the filter vessel and leaving the liquid manure in said vessel in a resting stage until a solid phase of the manure is collected on the top of the filter vessel and the liquid phase is collected therebelow;
- discharging the liquid phase from the vessel to such an extent that the solid phase almost reaches the bottom of the filter vessel;
- interrupting said discharging step and waiting for a renewed separation of the solid phase from the liquid phase and for collecting the solid phase on the top of the vessel and the liquid phase therebelow;
- and discharging a liquid phase of the manure newly collected in the filter vessel.
