Abstract
Disclosed herein is an ion-exchange treatment apparatus for dispersions, which comprises (1) a main circuit including (a) a first separation means for separating coarse particles among dispersoids from a raw dispersion supplied thereto, (b) an ion-exchange treatment column containing a particulate ion-exchange resin having a single polarity, (c) a second separation means for separating the remaining dispersoids from the dispersion subjected to the ion-exchange treatment and (d) a flow path line for causing the means (a), (b) and (c) to communicate in series, and (2) a circulating circuit for returning at least part of the dispersion treated in the second separation means (c) to the first separation means (a). Another apparatus in which at least one combination of a separation means and an ion-exchange treatment column containing a particulate ion-exchange resin having a single polarity is arranged further in the main circuit is also disclosed.
