Abstract
Falling film type of freeze concentration equipment developed as application of ice thermal storage can condense and cut down waste water, though it is ice thermal storage. By this equipment, four merits, heat use, waste water curtailment, reuse of water, and recovery of valuables, are obtained. The separation performance changes with ice-making speed, the kind of solution, quality, and concentration. If adapted for the expensive industrial waste water of processing expense, at least the merit of waste water curtailment can be collected for a short period of time. Thus, it can be said that this equipment is a hybrid system in consideration of environmental load reduction.
