Mechanical Separation

GEA Westfalia Separator

The comparative capacity refers to various decanters from GEA Westfalia Separator and is below the max. throughput capacity. The effective capacity depends on the extent to which the inflowing mixture can be clarified, the level of solids contained in the feed, the dry matter content required in the discharged solids and the level of solids permissible in the clarified liquid. In general, the machine can be adjusted to take account of the above requirements.
