Development of a novel high performance continuous cake-less filtration system.

A new cake-less continuous filtration system has been developed for large-scale treatment. Sericite slurries prepared by adding water glass as dispersant were filtered by the developed filtration system. It was shown that a spiral guide rod inserted into a ceramic tube filter is very effective for the cake-less continuous filtration. This system achieves much higher filtration rate compared to a conventional cross-flow filtration and we can collect much denser concentrate continuously without any cake formation.
