DEFINITION

Classification: 204/627

Barrier separator (e.g., electrodialyzer, etc.):

(under subclass 600) Apparatus having a filter or membrane (e.g., electrodialyzer, etc.) to separate some ions or particles from other ions or particles by allowing some ions or particles to pass through the barrier while the others are retained at or stopped from passing through the barrier.

(1) Note. This subclass and the subclasses indented hereunder are not intended to provide for the mere use of a perforated electrode.
