A rinse process in which the rinse water is applied to the softener bed at the end of brine regeneration at a faster rate of flow than that for which the brine was applied. Because of the greater density of the brine, it moves down through the bed in a piston-like fashion. If rinsing were to continue at this rate until the chlorides had dropped to the acceptable level at which the unit could be returned to service, the time required would be excessive. After the higher concentrations of brine have passed from the unit, little is gained by prolonging the rinse time. The rinse rate during the last few minutes is increased approximately fivefold to complete the rinse cycle. This fast rinse quickly removes the last traces of chlorides and significantly reduces the regeneration time.
