Abstract: 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.

Abstract: 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.

Abstract: The present invention provides a method and system of anticipating salt depletion in a brine tank of a water softener system, the system including a controller having a user interface and display, the method comprising the steps of tracking salt usage; determining the amount of salt remaining in the brine tank; calculating the number of days before salt is required in the brine tank based on salt usage and the amount of salt remaining in the brine tank; and providing an indication of the number of days to empty, whereby a user is able to anticipate the need to replenish the salt supply and plan accordingly to assure continuous satisfactory operation of the water softener system.

Abstract: 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.

Abstract: A system is provided for monitoring the status of a water softener at a remote location. The system includes a water softener controller with a control processing unit for determining the status of the water softener. The system also includes a water softener transmitter and a water softener indicator. The transmitter is coupled to the controller and transmits the status of the water softener to the indicator. The water softener indicator receives and displays the status message. The system is capable of determining whether the water softener is operating normally, whether the salt level is low or whether the water softener needs servicing.

Abstract: A potassium permanganate feeder has an inlet container and an outlet container disposed in an outer container. An inlet tube disposed in the inlet container supplies fill water which flows out of the inlet container through a porous screen to dissolve potassium potassium crystals. The resulting potassium permanganate solution flows into the outlet container through a porous screen where it may be withdrawn through an outlet tube disposed therein.

Abstract: 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.
