Abstract
A system for the combined softening of water and reduction of dissolved solids from the water, which can be retrofitted to a conventional water softening apparatus, includes a pressure tank, an inlet line for conveying raw or hard water to the pressure tank, and an outlet line for conveying softened water from the tank. Treatment material is located within the pressure tank for softening the water within the tank. At least one semi-permeable reverse osmosis membrane element is embedded within the treatment material for filtering the softened water within the pressure tank. A collection conduit and holding tank communicates with the membrane element and conveys filtered water from the pressure tank and stores the water.
