Title: Ion exchange water softening plant - counting water flow for automatic programmed regeneration of softening cartridge contents
Inventor: NEUKAMM ERICH
IPC: B01J49/80
Filed: 1973-08-04
Abstract: The regeneration of the ion-exchange resin in the cartridge of a domestic water softening plant is initiated by a pressure switch which counts the flow of hte crude water and operates, through a programmed control, a valve bank. When regeneration is due, brine from the salt container is passed into the cartridge, the overflow passing to the sink, and a flushing flow then being passed through the cartridge. Device is a simple automatic system based on counting and recording the water flow rate in a program register. Each valve can be individually adjusted to provide the desired effect. This principle is applicable to very small to very large softening plants.
