Advancements In Osmotically Driven Membrane Systems Including Multi-Stage Purification
US Patent:
2020008, Mar 19, 2020
Filed:
Nov 14, 2019
Appl. No.:
16/684406
Inventors:
- San Leandro CA, US

Abstract:
An example water purification system for purifying high concentration feed solutions includes a high rejection forward osmosis module, one or more low rejection modules, and a high rejection reverse osmosis module. The low rejection modules may have different rejection levels. The system may be pressurized by one or more pumps. One or more of the low rejection modules may include one or more nanofiltration (NF) membranes. The draw solution may comprise a monovalent salt, a multivalent salt, or a combination of both.
Advancements In Osmotically Driven Membrane Systems Including Low Pressure Control
US Patent:
2016003, Feb 11, 2016
Filed:

Appl. No.:
14/777406

Abstract:
An example water purification system includes a forward osmosis module, a reverse osmosis module, a pump powered by an electric motor, and a pressure sensor. The forward osmosis module may receive a feed stream and a draw stream, and may produce an intermediate product stream. The intermediate product stream may be pressurized by a pump and provided to the reverse osmosis module. The reverse osmosis module may generate a product stream and return the draw stream to the forward osmosis module. The pressure sensor may monitor the pressure of the intermediate product stream, and the pressure may be used to determine the speed of the electric motor.
