Abstract
Process for separating the ice crystals contained in a slurry of an aqueous solution and ice crystals from the aqueous solution and washing the ice crystals with an aqueous wash liquid, whereby a packed bed of ice crystals is created which is subjected to a continuous translatory movement, while a washfront is being created within the packed bed of ice crystals between the aqueous solution and the aqueous wash liquid, the aqueous solution and the aqueous wash liquid adjacent to the washfront being substantially stagnant, a stable washfront being created lying in a plane perpendicular to the translatory movement of the packed bed of ice crystals.
