1-23. (canceled)
A process for processing a solution;
- the process comprising:
- with a reverse osmosis system including at least:
- (i) a first reverse osmosis unit positioned to receive solution to be processed;
- the first reverse osmosis unit including:
- a high pressure side inlet;
- a high pressure side outlet;
- a low pressure side inlet;
- and a low pressure side outlet;
- (ii) a concentrate outlet-generating reverse osmosis unit;
- the concentrate outlet-generating reverse osmosis unit including:
- a high pressure side inlet;
- a high pressure side outlet;
- a low pressure side inlet;
- and a low pressure side outlet;
- and,
- (iii) an intermediate reverse osmosis unit system including at least one intermediate reverse osmosis unit, each intermediate reverse osmosis unit in the intermediate reverse osmosis unit system having:
- a high pressure side inlet;
- a high pressure side outlet;
- a low pressure side inlet;
- and a low pressure side outlet;
- operating the reverse osmosis unit system such that:
- (i) solution is directed into the first reverse osmosis unit with splitting of the solution and directing a portion of the solution into each of the high pressure side inlet and low pressure side inlet of the first reverse osmosis unit;
- (ii) an outlet flow from the first reverse osmosis unit is directed into a reverse osmosis unit of the intermediate reverse osmosis unit system;
- and,
- (iii) an outlet flow from a reverse osmosis unit of the intermediate osmosis unit system is directed into both the high pressure side inlet and low pressure side inlet of the final concentrate-generating reverse osmosis unit.

A process for processing a solution;
- the process comprising:
- using a reverse osmosis system including at least:
- (a) a concentrate outlet-generating reverse osmosis unit;
- the concentrate outlet-generating reverse osmosis unit including:
- a high pressure side inlet;
- a high pressure side outlet;
- a low pressure side inlet;
- and a low pressure side outlet;
- (b) an intermediate reverse osmosis unit system including at least one intermediate reverse osmosis unit, each intermediate reverse osmosis unit in the intermediate reverse osmosis unit system having:
- a high pressure side inlet;
- a high pressure side outlet;
- a low pressure side inlet;
- and a low pressure side outlet;
- and,
- operating the reverse osmosis unit system such that:
- (i) outlet flow from a selected reverse osmosis unit in the intermediate reverse osmosis unit system is split and a portion is directed into an inlet of the same selected reverse osmosis unit and a portion is directed into another reverse osmosis unit.

A process for processing a solution;
- the process comprising:
- with a reverse osmosis system comprising a plurality of reverse osmosis units and includes at least:
- (i) a first reverse osmosis unit;
- (ii) a second reverse osmosis unit;
- and,
- (iii) a first reverse osmosis unit pump configured to pump solution into the first reverse osmosis unit;
- and,
- (b) operating the reverse osmosis system such that:
- (i) at least a portion of high pressure side outlet flow from the first reverse osmosis unit is directed into the second reverse osmosis unit;
- (ii) at least a portion of outlet flow from the second reverse osmosis unit is directed into the first reverse osmosis unit;
- (iii) the second reverse osmosis unit is operated with:
- a high pressure side inlet feed;
- a low pressure side inlet feed;
- a high pressure side concentrate outlet;
- and, a low pressure side outlet;
- (iv) a reverse osmosis unit in the reverse osmosis unit system comprises a final reduced-solute solvent-generating unit and is operated with:
- a high pressure side inlet feed;
- a high pressure side concentrate outlet;
- a low pressure side outlet;
- and no pressure side inlet;
- and,
- (v) at least a portion of outlet flow from the second reverse osmosis unit is directed back into the second reverse osmosis unit as at least a portion of feed thereto.
