Abstract: A water treatment system having an inlet for receiving water to be treated and a manifold that defines a pair of fluid streams communicating with the inlet. A valve module carried by the manifold controls the communication of water at the inlet with treatment cartridges and with a common outlet. The valve module includes a valve member that is movable between two positions such that, in one position, the valve member communicates each fluid stream with an associated cartridge and, in a second position, communicates the inlet with the common outlet and bypasses the cartridges. A remotely mounted cartridge depletion indicator is provided that includes a linkage that is magnetically coupled to a stem assembly located within a flow metering mechanism. Movement in the internal stem assembly is transferred via the magnetically coupled external linkage to a cartridge depletion indicator visible to the operator.

Abstract: A control valve assembly including a water meter usage assembly including discs which are relatively positionable to adjust the frequency at which regeneration in a water treatment system starts. A regeneration control disc mounted coaxially with the meter disc assembly includes structure for releasing a drive mechanism associated with the meter disc assembly to rotate it back to a start position under a predetermined operating condition. The discs are releasably held in their relative positions by at least one pawl and at least one of the discs is rotatable relative to the other disc. The regeneration frequency is determined by an initiation slot in one of the discs and its operative position is determined by disc positions. The regeneration control disc is rotated by a pawl mechanism that is activated when an associated cam follower is received by the regeneration initiation slot formed in the water meter usage assembly.

Abstract: 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.

Abstract: A fluid treatment system for treating feed water includes a first tubular member having first and second ends, at least one second tubular member having first and second ends, a pump positioned within the first tubular member, a filtering membrane positioned within the second tubular member, a first end cap for receiving the first ends of the first and second tubular members, and a second end cap for receiving the second ends of the first and second tubular members.

Abstract: A control valve for a water treatment system which includes a turbine rotatably mounted within a water receiving chamber. A pair of nozzles communicate water from a water receiving chamber to the turbine in a driving relationship. The nozzles each define a passage, preferably converging slightly in cross-section and defining centerlines that converge and intersect at a region swept by the turbine. Preferably, the intersection of the centerlines occurs intermediate a circle defined by central regions of the turbine blades and a circle defined by peripheral edges of the turbine blades. At least one of the nozzles is slidably held in a slot formed in a dividing wall forming part of the control valve and is replaceable by a plug. A confronting surface defines a uniform gap between an outlet side of the nozzles and a peripheral portion of the turbine.
