1. A reverse osmosis system comprising:
- a pressure tank having an open end,an expandable bladder received within said pressure tank, said bladder having an open end,means for securing and sealing said open end of said bladder in said open end of said pressure tank, so as to form a first enclosed variable volume between said pressure tank and said bladder,a second tank assembly including a second tank received within said bladder, said second tank having an open end and a closed end,means for securing and sealing said second tank assembly in the open end of said bladder, so as to form a second enclosed variable volume between said bladder and said second tank,a prefilter and a reverse osmosis membrane assembly received within said second tank,said second tank assembly including a cap for closing said open end of said second tank,said second tank assembly having a first opening through which raw water may enter said second tank, such that the raw water may flow through said prefilter to said reverse osmosis membrane assembly,said second tank assembly having a second opening through which purified product water which has passed through said prefilter and said reverse osmosis membrane assembly may flow into said second variable volume,said second tank assembly having a third opening through which concentrated water which has passed through said prefilter but not through said reverse osmosis membrane assembly may flow for disposal,said second variable volume having a discharge opening through which purified product water may flow for use,whereby a reverse osmosis system including a prefilter, a reverse osmosis assembly and a storage tank for purified product water is constructed as compact assembly.

Abstract
A reverse osmosis water processing and storage system having a prefilter, reverse osmosis membrane assembly, and a storage volume contained within a first tank. The prefilter and reverse osmosis membrane assembly are located within a second tank which is in turn located within an expandable bladder which is received within the first tank. Processed water is stored in the volume provided between the second tank and the expandable bladder.
