A purified water storage system for a reverse osmosis purification unit has a container containing an interior chamber defined in part by a flexible wall member, such as a bladder or diaphragm, for receiving and containing purified water. A second chamber for containing pressurized air exists on the opposite side of the flexible wall member. The second chamber is at least 75%, preferably 80%, and still more preferably 100% of the maximum volume of the water-containing chamber.

1. A purified water container system comprises a container having rigid walls capable of holding a fluid under pressure, a first chamber within said container, a flexible impermeable bladder mounted within said first chamber, walls means in the container for precluding expansion of the bladder
1. A purified water container system comprises a container having rigid walls capable of holding a fluid under pressure, a first chamber within said container, a flexible impermeable bladder mounted within said first chamber, walls means in the container for precluding expansion of the bladder beyond a predetermined volume, a second chamber having a volume of at least 75% of the volume of the first chamber, at least one passageway connecting said first chamber with said second chamber, conduit means for passing purified water from a reverse osmosis purification unit into and out from the bladder under pressure to said bladder, and supply means for providing a gas under pressure to said chambers, said system being constructed such that when the bladder is filled to the maximum capacity, a volume of pressurized gas approximately equal to at least 75% of the bladder volume exists in said second chamber to enable the maintenance of a substantial pressure drop across said reverse osmosis unit. 2. The system of claim 1 wherein the second chamber is inside said container. 3. The system of claim 1 also comprising a second walled container, wherein the second chamber is inside said second container. 4. The system of claim 3 wherein said two containers are connected by a conduit. 5. The system of claim 1 also comprising means to permit flow of gas around the entire exterior of the bladder when the bladder is fully inflated. 6. The system of claim 1 wherein volume of the second chamber is at least about 80% of the volume of the first chamber. 7. The system of claim 1 wherein volume of the second chamber is at least about 100% of the volume of the first chamber. 8. The system of claim 1 wherein the bladder is filled with water, and the second chamber is filled with pressurized air. 9. The system of claim 1 also comprising removable closure means for sealingly enclosing said container, conduit means through said closure means communicating with the interior of the bladder and an elongate tube having a plurality of longitudinal bores therein communicating with the conduit means. 10. A purified-water container system comprising a container having rigid walls capable of holding a fluid under pressure, a first expandable and contractable chamber within said container for containing purified water, said chamber being defined by at least one flexible wall, conduit means for passing purified water from a reverse osmosis unit into and out from the first chamber, a second chamber for containing gas under pressure, said second chamber also being defined in part by said flexible wall, supply means for providing a gas under pressure to said second chamber, and said second chamber having a minimum volume of at least 75% of the maximum volume of the first chamber, said system being constructed such that when the first chamber is filled to the maximum capacity, a volume of pressurized gas approximately equal to at least 75% of the first chamber exists in said second chamber to enable the maintenance of a substantial pressure drop across said reverse osmosis unit. 11. The system of claim 10 wherein the second chamber has a minimum volume of at least 80% of the maximum volume of the first chamber. 12. The system of claim 10 wherein the second chamber has a minimum volume of at least 100% of the maximum volume of the first chamber. 13. The system of claim 10 wherein the flexible wall comprises a thin, impermeable membrane. 14. The system of claim 10 wherein the membrane is a bladder. 15. The system of claim 10 wherein the membrane is a diaphragm. 16. The system of claim 10 also comprising an elongate tube communicating with the conduit means and having a plurality of longitudinal bores therein.
