Abstract
A method and apparatus is provided for removing contaminants or for recovering valuable minerals in trace amounts by ion exchange treatment of liquids such as municipal and industrial waste waters, ore mining and processing tailings, and the like as they flow through a resin bed wherein ions in the liquid are sorbed into the resin by an ion exchange mechanism. The resin bed is a folded, moving bed which exhibits all of the advantages of a packed ion exchange resin bed. Laminar flows are developed throughout the moving bed system to maintain all interfaces intact, even during the rinsing operation, while the moving bed used is of a 'folded' type having a maximum height approximately one-third that of conventional countercurrent units. The ion exchange treatment occurs within a loading vessel resin bed, the beads in the feed portion of which become exhausted and sequentially move out of the loading vessel for subsequent regeneration and rinsing, followed by eventual return to the loading vessel.
