摘要:
A water softener and a method of operating the same are provided to allow for the efficient use of either NaCl or KCl as the regenerant salt. A user interface is provided to allow the user to indicate to the computer controlling the water softener whether NaCl or KCl is being used. The computer controller adjusts the fill time and brine time, depending on the type of regenerant salt used and on the temperature of the brine.

A method of manufacturing a valve rotor with a wear-resistant, low-friction surface, wherein a disk having angled edges and a shape which correspond with the surface of the rotor is formed from a sheet of polytetrafluoroethylene (PTFE). The disk is placed at the bottom of a mold cavity, and a plastic material is injected in the mold. The plastic fills the mold cavity surrounding and covering the angled edges of the disk. Once hardened, the plastic is locked together with the angled edges of the PTFE disk. In a preferred embodiment, a method of manufacturing a water treatment valve rotor with a PTFE rotating surface is shown.

The present invention provides an apparatus and method for aeration in a filter system. The present invention provides an air injection adaptor for coupling between a filter tank and a valve controller. The air injector adaptor includes an unfiltered water inlet adapted for coupling to the unfiltered water outlet of the valve controller; an unfiltered water outlet in fluid communication with the unfiltered water inlet of the adaptor, the adaptor unfiltered water outlet adapted for coupling to the opening at the upper end of the tank; a filtered water inlet adapted for coupling to the upper end of the stand pipe; a filtered water outlet in communication with the filtered water inlet of the adaptor, the adaptor filtered water outlet adapted for coupling to the filtered water inlet of the control valve; an air source inlet adapted for coupling to a regulated air source; an air source outlet in communication with the air source inlet and adapted for opening into the upper end of the tank; and a vent, the vent having a vent inlet and a vent outlet in communication with the vent inlet, the vent inlet opening into the upper end of the tank.

摘要:
A bypass valve for directing a supply flow either through a treatment tank to the distribution system, or for bypassing the treatment tank and directing the supply flow through the valve directly to the distribution system. In the bypass position, the treatment tank may be physically removed from the bypass valve, the bypass valve serving as a disconnect. While in the bypass position, the valve may be actuated to pressurize the treatment tank from the supply flow.
摘要:
The solenoid plunger normally closes the center vent hole in the diaphragm so inlet pressure is applied through the bleed hole to the space above the diaphragm resulting in enough pressure to close the diaphragm on the valve seat. When the solenoid is actuated, the plunger is lifted, allowing water to flow through the vent faster than it can flow through the bleed hole. This lowers the pressure above the diaphragm so inlet pressure can move the diaphragm from the seat and full flow can take place. The bleed hole is quite small. To prevent entrained particles from reaching and plugging the bleed hole, an arcuate groove having a width less than the bleed hole diameter is molded into the diaphragm to trap particles in the groove and prevent the particles from reaching and closing the bleed hole.

The present invention provides a water treatment system, such as a water softener, with a resin tank having a top distributor with a preliminary screen and second screen. The preliminary screen provides added protection by reducing the chance of larger particles from entering the various valves and screens. Prior to the regeneration cycle, an additional back wash and fast rinse cycle are added to rinse sediment to the drain and to clean the preliminary screen.
摘要:
A demand initiated method for regenerating a water softener which operates the softener ion exchange bed over a capacity range in which the resin is most efficiently restored by exposure to brine. The reserve capacity of the softener is adjusted in response to the amount of softening capacity used since the last regeneration, as is the quantity of saturated brine to be used for the next regeneration, which is scheduled when the reserve capacity is exceeded, or the remaining available capacity will not be adequate for normal usage on the next day of the week.
