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, is disclosed. The system includes a pressure tank having a closure with an access opening, an inlet line for conveying hard water to the pressure tank, an outlet line for conveying softened water from the tank and having a mouth located proximate the bottom of the tank, pelletized treatment material located within the pressure tank for softening the raw water, a plurality of tubular membrane carriers embedded within the treatment material, a plurality of semi-permeable reverse osmosis membranes enclosing the tubular membrane carriers, and a conduit for collecting the purified water from the membrane carriers. The conduit includes a plug sealing the access opening and having an upper recess and a plurality of passages communicating with the recess, a plurality of flexible tubes, each extending between a membrane carrier and a passage so that purified water may pass from the membrane carrier to the plug. A pure water line is attached at an end to the recess of the plug and communicates with a holding tank to which water is supplied.
