ABSTRACT:
A plant for reducing the impurity content of impure water by the immiscible refrigerant freeze process, for example a secondary refrigerant freezing plant employed for desalination, has its crystallizer sub-divided into a plurality of tiers of passageways and supplied in parallel with impure water. Thus the crystallizer may be built to a height which matches the configuration of the usual wash column so that together the two components can be housed in a conveniently cylindrical shell along with the decanter and the melter/condenser.
