One of the most used techniques for manure treatment in Flanders is the separation of the manure in a liquid and a solid fraction.

In this way, nitrogen and potassium are concentrated in the liquid fraction and most of the phosphorus and organic matter remains in the solid fraction.

To separate manure different techniques are available and the choice depends on the type of manure, the desired end product, the volume of the manure to be separated, etc. In Flanders, centrifuges, screw presses and belt presses are mainly used.
