Abstract: A control valve for a reverse osmosis water purifying system provides a feed water port, a squeeze water port, a drain port, and a product water connection, each of which open into a bore. A first, second, and third O-rings are located in the bore successively between the feed water port, the squeeze water port, the drain port, and the product water connection. A control piston is moveably located in the bore of the housing. The control piston includes a vent/drain well in which a side is chamfered and at least one recess disposed around an end of the control piston. The vent/drain well provides a fluid passage between the squeeze water port and the drain port when the vent/drain well passes over the second O-ring. The fluid passage includes an opening formed between the second O-ring and the chamfered side of the vent/drain well, where the size of the opening is responsive to the position of the control piston.

Abstract: Parallel processing reverse osmosis water filtration systems using multiple RO (reverse osmosis) filter systems having their raw water input connections coupled together, their product water output connections coupled together and their drain connections coupled together. Using appropriate valving, any one or more reverse osmosis filter systems may be decoupled from the rest of the system for servicing without shutting down the entire system, and one or more additional reverse osmosis filter systems may be added to increase the product water output capacity when needed. Optional features disclosed include enhanced product water storage capacity, control of the total dissolved solids in the product water dispensed, and protection against leaks that may disable one RO filter system, but not the entire parallel processing reverse osmosis water filtration systems. Various embodiments are disclosed.

Abstract: Methods and apparatus for providing water with a selectable total dissolved solids content. The apparatus includes a reverse osmosis filter system to provide filtered water having a dissolved solids content less than the selectable total dissolved solids content and for mixing water having a dissolved solids content exceeding the selectable total dissolved solids content with the filtered water in a ratio to provide water with the selectable total dissolved solids content. Various embodiments are disclosed.
