Description

In einem Anwendungsbeispiel wurde durch kurzseitiges Turbi- . nieren des Faulsohlamme die Absetzgeschwindigkeit auf den 20-fachen wert gesteigert. Gleichseitig resultierte eine erbeblieh verbesserte Zentrifugier- bzw. Separierbarkeit des Faul--sohlammer. In an application example, short-sided Turbi-. kidney of the lazy lamb, the weaning speed has been increased by a factor of 20. At the same time, this resulted in a hereditary improvement in centrifugation and separability of the digester hammer.
