Abstract
Apparatus for use in an ion exchange unit or column comprising a riser pipe, a port coupled to one end of said pipe, a first rigid cylinder having apertures therein mounted concentrically on the pipe, a port coupled to the space between the pipe and said cylinder, a mesh sleeve concentrically mounted about the cylinder, a sieve mounted about the mesh sleeve, a second rigid cylinder concentric with the pipe and near its outer end, a second mesh sleeve mounted about said second rigid cylinder and a sieve bag containing the second mesh sleeve. The aperture size in said sieve material is only sufficiently fine to prevent the passage of ion exchange resin beads.
