Abstract:
1. A method of operating a water treatment system that includes a pair of ion-exchange water softener tanks connectable to a source of pressurized water and with a water system to supply softened water to the water system, the tanks each being capable of regeneration by flushing with a regeneration solution to replenish depleted ions, the method of operating the water treatment system, comprising: a) regenerating a selected one of the tanks with a brine solution wherein hard ions are removed from a resin in the tank and exchanged with soft ions, the brine solution being contained in a container in communication with the selected tank wherein the container includes a salt material disposed on a screen above a brine reservoir and further includes a brine well in communication with the brine reservoir, the brine reservoir defining the brine solution; b) replenishing brine after the tank regeneration cycle is complete wherein the step of replenishing the brine includes; (i) flowing water from a first nozzle directly into a brine well of the system for initially diluting the brine in the reservoir, and (ii) flowing water from a second nozzle directly onto a salt material for generating additional brine solution in the reservoir.
