Abstract:
In a continuous ion-exchange process in which resin moves intermittently through a circuit including an absorber and a regenerator, the absorber is spanned by a liquid-distributing system, and at each intermittent movement a slug of resin wholly occupying the space in the absorber between this system and one end of the absorber is discharged while service flow continues. The remainder of the bed in the absorber is moved in the direction of the space thus emptied so as to fill it again and a slug of regenerated resin of identical volume is introduced into the other end of the absorber.
