Abstract
A water softening system includes a resin tank which has an open drain during a regeneration cycle, and a pressurized brining system communicating with the resin tank. The brining system includes a closed brine reservoir with an outlet communicating with the resin tank and an inlet adapted to be coupled to a pressurized source of water, a salt reservoir at atmospheric pressure, and a semi-permeable membrane in communication with and forming a partition between the reservoirs and allowing free movement of salt ions therethrough while substantially inhibiting flow of water therethrough to form brine in the brine reservoir, which brine is then urged through the brine outlet and into the resin tank by the water pressure in the brine reservoir.
