Abstract: A countercurrent liquid-solid contacting apparatus comprises a liquid purifying column for substantially purifying a liquid by passing the liquid upwardly through a bed of purifying material and a regenerating column for regenerating the purifying material used fo purify the liquid. The liquid purifying column includes supply and transfer ports defined respectively at the top and bottom thereof and has therein the bed of purifying material which is spaced a predetermined distance from the top of the liquid treating column to provide a vacant space. The purifying column further includes a liquid inlet and outlet with a portion of the purifying bed above the liquid outlet serving as a settling layer to avoid any possible fluidization and/or expansion of the purifying material.
