ABSTRACT:
An ion exchange apparatus having a plurality of channels or manifolds used for liquid distribution and collection purposes within an end of a container adjacent to an ion exchange resin bed can be improved by using a check valve permitting flow in one direction to all of the channels as the bed is being employed under "service" conditions to treat water and permitting flow in the opposite direction in less than all of the channels as the bed is being treated with a regenerant solution. Such use of less than all of such panels during the treatment of the bed with the regenerant solution makes it possible to achieve good distribution of a relatively small amount of the regenerant solution and to receive regeneration of the bed utilizing such a comparatively small amount of the regenerant solution.
