Abstract: A movable bed water softening apparatus is provided wherein the resins in their regenerated state are supplied into the upper portion of a closed softener tank. The resins pass downwardly through the tank around a centrally disposed water supply pipe and the water passes radially outwardly through the movable bed of resins into a peripheral collector. The spent resins are passed through a regeneration column having a double wall arrangement wherein the spent resin particles are introduced at the top of the column and passed downwardly between the double walls and subsequently pass upwardly through the passage defined by the innermost wall in opposition to a flow of regenerating brine. The regenerated resin is then passed upwardly through a rinsing column and returned to the top of the softener tank.
