Abstract:
The present application provides a switchable forward osmosis system, and processes thereof. In particular, this application provides a process for treating an aqueous feed stream, comprising: forward osmosis using an aqueous draw solution having a draw solute concentration of ≥20 wt %, the draw solute comprising ionized trimethylamine and a counter ion; wherein, the feed stream: (i) comprises ≥5 wt % total dissolved solids; (ii) is at a temperature of ≤20° C.; (iii) is at a temperature between ≥30° C.-≤60° C.; (iv) has an acidic pH or a basic pH; (v) comprises organic content; (vi) comprises suspended solids; (vii) or any combination of two or more of i)-v). Also provided herein are the related system and draw solution for performing the process, and various uses thereof for treating typically difficult to dewater feed streams.

Claim (Index 19):
A forward osmosis system, comprising:\n an aqueous draw solution having a draw solute concentration of \u226520 wt %, the draw solute comprising ionized trimethylamine and a counterion; and at least one forward osmosis element, comprising\n a semi-permeable membrane that is selectively permeable to water, having a first side and a second side; \n at least one port to bring a feed solution in fluid communication with the first side of the membrane; and \n at least one port to bring the draw solution in fluid communication with the second side of the membrane, \n wherein water flows from the feed solution through the semi-permeable membrane into the draw solution to form a concentrated feed solution and a diluted draw solution.
