Claim 21:
22. The crystallization apparatus according to claim 19, wherein
the treatment container provided with the porous membrane, a source of raw material liquid, the treatment liquid supply unit, the extraction unit, and the aging unit form a crystallization module, the crystallization apparatus comprising a plurality of crystallization modules connected in series, and
wherein for a first crystallization module among the serially-connected plurality of crystallization modules the raw material liquid supply unit is the source of raw material liquid, and
wherein, other than for a last crystallization module among the serially-connected plurality of crystallization modules, a mixed liquid flowing out of the aging unit of each one crystallization module among the serially-connected plurality of crystallization modules is supplied as the raw material liquid to a next crystallization module among the serially-connected plurality of crystallization modules, said mixed liquid supplied as the raw material liquid having had a precipitated crystal removed in the aging unit of said one crystallization module.
