Abstract
A separator particularly useful in freeze concentration systems and apparatus, particularly multi-stage countercurrent systems for concentrating aqueous feed liquid, but useful for other kinds of separators as well. The slurry to be separated enters a vessel in which is mounted and rotated a cylindrical filter. The liquid passes through the filter to one outlet while the solids accumulate on the filter and are removed and directed to another outlet by a fixed scraper.
