Abstract
The present invention is directed towards a lining of a pulsed column which allows for an extended exchange of the solid phase with the liquid phase. The lining is composed of stacked baskets and rings, the baskets having a perforate bottom and the rings having a central hole. The size of the perforations in the baskets are such that the solid phase is retained therein while the central hole in the rings allows the solid phase to pass therethrough and go on to the next lower basket. The inside of the column is subjected to high frequency, low energy pulsations which move the liquid and solid phase in a back-and-forth manner. Additionally, the inside of the column is subjected to extremely low frequency, high energy pulsations so as to remove one portion of the solid phase located in a basket and cause it to go down towards a next lower basket.
