bull Disposal of the waste brine can be the bulk of the water treatment cost

bull State of the art methods are reaching thermodynamic limits but the cost is still too high

bull FO requires little to no pre-treatment

Proposed COHO System

Figure 1 Schematic of COHO draw phase switching

The draw solution purifies wastewater (1) using osmotic potential to drive water across a selective membrane (2) The draw solution is generated using carbon dioxide from flue gas to switch the draw solute to the miscible aqueous phase Carbon dioxide (3) is released and clean water is produced (4) by using low-grade heat switching the draw solute (5) back to its original immiscible phase for mechanical separation

Porifera (2014)FO modeFeed DI water~25 ⁰C

CHP flux over a range of concentration feeds

bull FO flux tests against DI water can have limited implications on FO performance against a feed with real world osmotic pressures Thus tests against 05 and 10 molKg NaCl feed solutions

bull There is a modest flux attenuation for CHP vs DMCHA attributed to a shift is rheological properties associated with moving from a 8 to an 11 carbon amine

The draw solution purifies wastewater (1) using osmotic potential to drive water across a selective membrane (2) The draw solution is generated using carbon dioxide from flue gas to switch the draw solute to the miscible aqueous phase Carbon dioxide (3) is released and clean water is produced (4) by using low-grade heat switching the draw solute (5) back to its original immiscible phase for mechanical separation

The draw solution purifies wastewater (1) using osmotic potential to drive water across a selective membrane (2) The draw solution is generated using carbon dioxide from flue gas to switch the draw solute to the miscible aqueous phase Carbon dioxide (3) is released and clean water is produced (4) by using low-grade heat switching the draw solute (5) back to its original immiscible phase for mechanical separation

Proposed COHO System

Figure 1 Schematic of COHO draw phase switching

The draw solution purifies wastewater (1) using osmotic potential to drive water across a selective membrane (2) The draw solution is generated using carbon dioxide from flue gas to switch the draw solute to the miscible aqueous phase Carbon dioxide (3) is released and clean water is produced (4) by using low-grade heat switching the draw solute (5) back to its original immiscible phase for mechanical separation

CO2 Capture form simulated flue gas

bull CO2 capture from a simulant flue gas (10 CO2 90 N2) bull Need to capture 75 of the CO2 feed the solution while generating a

60 wt solution (osmotic pressure ~325 atm)bull Simplest system possible gas bubbled through a stirred solution

bull FO flux tests against DI water can have limited implications on FO performance against a feed with real world osmotic pressures Thus tests against 05 and 10 molKg NaCl feed solutions

bull There is a modest flux attenuation for CHP vs DMCHA attributed to a shift is rheological properties associated with moving from a 8 to an 11 carbon amine

The draw solution purifies wastewater (1) using osmotic potential to drive water across a selective membrane (2) The draw solution is generated using carbon dioxide from flue gas to switch the draw solute to the miscible aqueous phase Carbon dioxide (3) is released and clean water is produced (4) by using low-grade heat switching the draw solute (5) back to its original immiscible phase for mechanical separation

Proposed COHO System

Figure 1 Schematic of COHO draw phase switching

The draw solution purifies wastewater (1) using osmotic potential to drive water across a selective membrane (2) The draw solution is generated using carbon dioxide from flue gas to switch the draw solute to the miscible aqueous phase Carbon dioxide (3) is released and clean water is produced (4) by using low-grade heat switching the draw solute (5) back to its original immiscible phase for mechanical separation
