Brine concentration using forward osmosis may be achieved using a high osmotic pressure draw solution with a means to recover and regenerate it. One such process uses the ammonia-carbon dioxide (NH 3 /CO 2) forward osmosis process invented at Yale University [13] [14] by Rob McGinnis, who subsequently founded Oasys Water to commercialize the ...
As a scientist, McGinnis is known for his contributions in the domain of desalination and forward osmosis; [1] in particular he is credited as a co-inventor of the NH 3 /CO 2 draw solution for the forward osmosis (FO) desalination process. [6] [7] [8] McGinnis is CEO at Prometheus Fuels, an environmental technology startup company he founded in ...
Because forward osmosis is being used, the process is relatively energy-efficient. Epsom salt can also be taken from the bittern draw solution once it is used. [ 13 ] This method is particularly useful in areas where sugarcane and salt production are in close proximity to avoid costs associated with movement of either the sugarcane juice or the ...
A 2012 study on efficiency from Yale University concluded that the highest extractable work in constant-pressure PRO with a seawater draw solution and river water feed solution is 0.75 kWh/m 3 (2.7 kJ/L) while the free energy of mixing is 0.81 kWh/m 3 (2.9 kJ/L) — a thermodynamic extraction efficiency of 91.0%.

The host wasn't quite ready for the level of excitement from contestant Daniel after he nailed "Guppies" as the solution in the bonus round, as seen in the Jan. 21 episode of the game show.
Forward osmosis uses a semi-permeable membrane to effect separation of water from dissolved solutes. The driving force for this separation is an osmotic pressure gradient, such as a "draw" solution of high concentration.
