ABSTRACT:
Apparatus for removal of a desired material from a liquid is described, in which the liquid is cycled through a plurality of liquid treatment containers in a first direction and brought into countercurrent contact with a medium for recovery of the desired material cycled through the treatment containers in a second, opposite direction. After treatment of the liquid, the medium is advantageously regenerated in a plurality of medium regeneration containers. The used medium is cycled through a plurality of medium regeneration containers in a first direction and brought into countercurrent contact with a medium regeneration liquid cycled through the regeneration containers in a second, opposite direction. The apparatus further includes means for transferring at least a portion of the medium from the first liquid treatment container into the first medium regeneration container and means for transferring at least a portion of the at least partially regenerated medium from the final medium regeneration container into the final liquid treatment container.
