Abstract: A method and apparatus for controlling a fluid treatment apparatus that includes a resin tank containing an ion exchange media. A control valve controls the regeneration cycle and includes a regeneration control turbine operatively connected to a regeneration control disk forming part of a servo system. During regeneration, a meter flow of fluid emitted by a regeneration control nozzle produces rotation in the turbine to effect a regeneration sequence. Regeneration is initiated by a regeneration initiating nozzle which emits a stream of fluid at the turbine for a predetermined time interval in order to initiate a regeneration cycle. A control system includes a sensor for monitoring the fluid quality level of the source fluid or the treated fluid and initiates regeneration. When the control system is used with the disclosed control valve, the control system communicates presssurized fluid to the regeneration initiating nozzle upon sensing a predetermined quality level.
