Experimental study of wash columns used for separating ice from ice-slurry

The separation of ice from ice slurries is the final step in the process of freeze concentration, where wash column can be employed. Phenomena found in washing an ice bed, such as channeling, viscous fingering, clogging, liquid entrainment, and permeability were studied in an experimental wash column. The appropriate operating conditions that lead to a successful washing were proposed in this paper.
