Answer»

Right choice is (a) Screen/scroll centrifuge

Easiest EXPLANATION: For the filtration or the so-called screen centrifuge the drum is perforated and is inserted with a filter, for example a filter cloth, wire mesh or lot screen. The SUSPENSION flows through the filter and the drum with the perforated wall from the inside to the outside. In this WAY, the solid material is restrained and can be REMOVED. The KIND of removing depends on the type of centrifuge, for example manually or periodically.
