Water Resin

Water Resin

Water softening is a process in which water flows through a bed of resin to exchange the hardness ions, calcium and magnesium, for sodium ions.  When the resin has reached its capacity for holding hardness ions, the water softener initiates a regeneration cycle.  During this cycle, a sodium chloride brine solution flows through the resin and effectively reverses the process by exchanging sodium ions for hardness ions, and flushing the hardness ions down the drain.
