A method and apparatus for treating water including a tank having an inlet and outlet and a water treatment material or resin within the tank. A control valve assembly having multiple, separable levels houses a water usage metering mechanism and a regeneration control mechanism, each having associated turbines. An inlet/bypass valve communicates source water with the tank inlet or directly to a system outlet. When the treatment material is exhausted, it is regenerated by actuating the bypass valve to communicate the source water with the system outlet. The turbine driven regeneration control then sequences the steps of regeneration, including opening a control valve to communicate inlet water to a venturi in order to aspirate brine solution and deliver to the tank outlet. The brine solution passes through the treatment material and is discharged through the tank inlet which is communicated to a system drain. At the conclusion of this step, brine solution is blocked from the venturi and the tank is slow rinsed. Subsequently, the communication of the venturi with the tank inlet is blocked, but water is allowed to flow through the venturi and refill the brine reservoir. Water at the outlet is then communicated to the tank outlet to perform a fast rinse. At the conclusion of this step, the source water is communicated to the tank inlet and the bypass step is terminated.

Water treatment system

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. The control system preferably includes a programmable controller interconnected with a flow sensor and conductivity sensor and periodically samples the conductivity of the influent. Based on the conductivity and volume date provided by the sensors, the programmable controller maintains a running total of 'total grains' processed by the ion exchange material. When the total grains processed equals or exceeds a preset value which is related to the capacity of the resin bed, the control system initiates regeneration.
