Abstract
An improved process for continuous counter-current contact between a fluid to be treated and solid particles wherein the fluid flows through a column containing a plurality of contacting chambers each of which contains solid particles and in which intermittent transfer of the particles in a direction opposite to that of the fluid from each chamber to the chamber immediately adjacent is effected while maintaining a continuous flow of the fluid through the column.
