In a process for separating ice crystals contained in a slurry of an aqueous solution and ice crystals from said aqueous solution and washing said ice crystals with an aqueous wash liquid, a packed bed of ice crystals is created which is subjected to a continuous translatory movement, while a stable washfront is being created within said packed bed of ice crystals between said aqueous solution and said aqueous wash liquid, said aqueous solution and said aqueous wash liquid adjacent to said washfront being substantially stagnant, and said stable washfront being created lying in a straight plane perpendicular to said translatory movement of said packed bed of ice crystals. <IMAGE> |
