ABSTRACT:
The process for separating the solid particles in the column is based on the intermittent supply of pressurized suspension to the apparatus which pressure supplies the energy required for feeding the suspension near one end into the column, the squeezing of the suspension liquid out of the suspension under withdrawal of the suspension liquid from the column near that same end of the column, the compaction of the solid particles, the transport of the compacted bed of particles towards the opposite end of the column and the washing of the compacted bed with wash liquid, the bed is mechanically disintegrated, the product of this disintegration is removed in suspended form while maintaining a wash front separating the non washed and washed parts in the compacted bed.
