Forward Osmosis Technologies


Forward osmosis is a process, whereby water can be removed from saline feeds across a semi-permeable membrane by an osmotic “draw” solution, due to significant osmotic gradients between the saline feed and the draw solution. The diluted draw solution is subsequently separated from water and reused in the forward osmosis process loop.

Nrgtek Inc. has developed several new polymers, which have very intriguing properties: very high osmotic potentials, and the ability to phase separate from water either by application of heat or by inoculation of certain gases. Termed thermolytic or CO2-philic polymers, these osmotic polymers are easily regenerated for continued use, and available in industrial quantities from leading chemical manufacturers (BASF, Dow-DuPont, Clariant, Oxiteno etc).

Using these specialized polymers, Nrgtek Inc. has developed several new technologies of industrial significance.

 

US patents for the above technologies include:
