The BoCross Dynamic Filter is used for concentrating and washing of a modified and very fine titanium dioxide which has to be further processed. It is an important target of this application to achieve a clean product with high end concentration and to prevent any air contact.

The discontinuously produced suspension is collected in a storage tank which feeds the BoCross Dynamic Filter. The retentate is recycled to the storage/feed tank and diluted with wash water for washing out of inorganic salts. Wash water dosage is regulated by a level control. When the salt concentration in the retentate meets the required value the washed suspension is fed to the up-stream process step.
