APPARATUS AND METHODS FOR SOLUTION PROCESSING

摘要

Equipment, systems, processes and techniques for conducting processing of solutions are described. The techniques can be applied to provide diluted solution (i.e. purified solvent), concentrate solution or each. A variety of specific equipment, example systems and processes are depicted and described.

1. A process for processing solution; the process comprising steps of:
(a) providing a reverse osmosis system including at least:
(i) a first reverse osmosis unit having a high pressure side inlet, a high pressure side outlet, a low pressure side inlet and a low pressure side outlet;(ii) a second reverse osmosis unit having a high pressure side inlet, a high pressure side outlet, a low pressure side inlet and a low pressure side outlet;(iii) a third reverse osmosis unit having a high pressure side inlet, a high pressure side outlet, a low pressure side inlet and a low pressure side outlet;(iv) a first reverse osmosis unit pump positioned and configured to pump at least some liquid into the high pressure side inlet of the first reverse osmosis unit without the liquid passing through another reverse osmosis unit between the first reverse osmosis pump and the first reverse osmosis unit;(v) a second reverse osmosis unit pump positioned and configured to pump at least some liquid into the high pressure side inlet of the second reverse osmosis unit without the liquid passing through another reverse osmosis unit between the second reverse osmosis pump and the second reverse osmosis unit; and,(vi) a third reverse osmosis unit pump positioned and configured to pump at least some liquid into the high pressure side inlet of the third reverse osmosis unit without the liquid passing through another reverse osmosis unit between the third reverse osmosis pump and the third reverse osmosis unit; and, (b) operating the reverse osmosis unit system that:
(i) the first reverse osmosis unit pump pumps at least some liquid into the high pressure side inlet of the first reverse osmosis unit;(ii) the second reverse osmosis pump pumps at least a portion of liquid, received from the high pressure side outlet of the first reverse osmosis unit, into the high pressure side inlet of the second reverse osmosis unit without at least some portion of the liquid passing first through another reverse osmosis unit between the first reverse osmosis unit and the second reverse osmosis unit; and,(iii) the third reverse osmosis pump pumps at least a portion of liquid received from the high pressure side outlet of the second reverse osmosis unit, into the high pressure side inlet of the third reverse osmosis unit without at least some portion of the liquid passing first through another reverse osmosis unit between the second reverse osmosis unit and the third reverse osmosis unit.
