| Summary: | INTRODUCTION
Centrifugal deliquoring is used in many industrial
processes (e.g., chemical, food, pharmaceutical and
biotechnological processes). A high driving force for
solid liquid separation by a centrifuge can easily be
obtained, resulting in a short processing time.
However, during deliquoring of a slurry with poor
filterability by a centrifuge, cake with poor
permeability forms near the filter medium. Thus,
such a slurry cannot be separated effectively by a
conventional centrifuge.
A new deliquoring method is developed to solve
this problem. A schematic drawing of the new
method is shown in Fig. 1. In this method, a new
filter medium is placed parallel to the centrifugal
force. In this study, the effect of the new filter
medium on the consolidation process is evaluated,
and an analytical method for deliqouring process
using the new filter medium is proposed. |
