Abstract
A method of treating fluid in a bed of ion exchange resin wherein in one embodiment the resin is of a high kinetic type and water is introduced upwardly through the bed to effect a complete fluidized resin bed. The high kinetic resin is of a fine mesh type and preferably can be monospheric. An apparatus for carrying out the method is devoid of any elements which effect a compacting of the resin during normal operation. The method and apparatus is particularly directed to water treatment. In another embodiment, cocurrent proportional regeneration of a resin bed is effected using resins with nonoverlapping terminal velocities in two different ionic forms.
