Function SEPCOM® is a solids-liquid separating machine including a screw conveyor. Using both principles of separation, by gravity and by mechanical pressing, the machine is designed to separate the liquid phase from the solid phase in a wide range of substances such as sludge, sewage, manure, solids-liquid mixtures, vegetables, processing waste and others, where the percentage of liquid inside the solid may be considerably different. The separated solid and liquid phases can be handled in an easier and cheaper way. In some sectors this can even become a source of income. Operation The machine receives the material to be separated and conveys it using the screw conveyor inside the separator casing. The liquid phase is separated through the mesh of the cylindrical screen which encloses the screw conveyor. Along its path toward the exit, the material gradually separates progressively the less linked liquid and then the more strongly linked liquid until a plug of almost dry m
