ABSTRACT:
A bed of silver activated charcoal in combination with a downstream bed of a mixture of anion exchange resins and cation exchange resins aerate, purify, soften and dealkalize water flowing therethrough. Periodic flushing through a unit having a solution of sodium chloride or potassium chloride regenerates both exchange resins. An upright cylindrical container having screen separated compartments for the chemicals and filters receives tap water from a pressure reducing nozzle and discharges the conditioned water through a spigot. The unit containing the chemical regenerant is selectively connectable intermediate the nozzle and the container.
