Abstract
A brine system to manufacture brine for the regeneration of ion exchange material including a brine well positioned within a brine drum. A vertically adjustable air chamber activates a diaphragm and control arm assembly which in turn controls inlet shut-off valves associated with the brine well when the water level within the drum reaches a predetermined level. The control arm has a unique cam arrangement associated therewith which prevents premature shut-off of the valves. Water enters and is withdrawn from the brine well through a down tube having a vertically adjustable lower end extending down into the brine well to a predetermined level and an upper end in communication with the shut-off valves through a series of passageways and chambers. A floating disc seal is provided within one of these chambers to shut-off the air entering the chamber after the brine is drawn down to a level below the lower end of the down tube.
