Publication number: 20140069852Abstract: A water softening system includes apparatus that recycles a substantial percentage of the solution used for regenerating the system. This system conventionally includes a brine tank and a softening tank through which hard water from a source passes during normal operation. During a regeneration mode, the solution of sodium or potassium ions in the brine tank passes through the softening tank acquiring hardness ions, and then through a nanofilter that passes a much higher proportion of the sodium or potassium ions than the hardness ions from a high pressure side to a low pressure side. The hardness ions flow from the upstream end of the nanofilter through an outlet and into a drain. The liquid passing through the nanofilter contains salt that returns to the brine tank for reuse. A preferred embodiment tests the concentration of softening alkali metal ions in the liquid flowing from the softening tank during a fast rinse portion of the regeneration cycle.Type: ApplicationFiled: November 11, 2013Publication date: March 13, 2014Inventor: Peter S.
