ABSTRACT:
The present invention is an electronic control means for use in a resin-type ion exchange apparatus requiring periodic resin regeneration. A microprocessor operating in accordance with programs stored in a memory and predetermined constants entered by a programming means controls the initiation and operation of the regeneration sequence. According to one embodiment the regeneration sequence is initiated at predetermined times. According to another embodiment the regeneration sequence is initiated when a predetermined amount of fluid has passed through the ion exchange apparatus. During the regeneration sequence the electronic control means controls the valves for the regeneration steps of backwashing, brining, rinsing and sterilization.
