Continuous filtration of ice slurries (with particles of about 80 μm diameter) to generate potable water was investigated. In the filtration process the ice is driven through a stationary channel with liquid draining through narrow slots in the base. Most of the liquid drained from the slurry at ambient pressure and the residual liquid trapped in the pores of the consolidated ice bed was displaced to a vacuum after downstream rinsing with sprayed or melt water. The cost of this approach may be competitive with reverse osmosis if an automated unit is developed.
