Demand Initiated Regeneration (DIR)

A method of automatically initiating regeneration or recycling in filters, deionizers, or softeners after a pre-determined metered volume of water has been processed. In a softener or deionizer, regeneration may be triggered automatically based upon an electrical or mechanical signal. All operations including bypass (of hard or soft water depending upon design), backwashing, brining, rinsing, and returning the unit to service are initiated and performed automatically in response to the demand for treated water.
