Draw solution for forward osmosis
WebMay 1, 2016 · Switchable Polarity Solvent Forward Osmosis (SPS FO) is a semi-permeable membrane-based water treatment technology. INL is currently advancing SPS FO technology such that a prototype unit can be designed and demonstrated for the purification of produced water from oil and gas production operations. WebIn forward osmosis processes, the decontaminated water ends up in the high concentration draw solution and – if needed as an end product – must be subsequently separated from the draw solutes. Want an overview of …
Draw solution for forward osmosis
Did you know?
Forward osmosis (FO) is an osmotic process that, like reverse osmosis (RO), 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 that a "draw" solution of high concentration (relative to that of the feed solution), is used to induce a net flow of water through the membrane into the draw solution, thu… WebApr 12, 2024 · Metal–organic frameworks (MOFs) can be applied to enhance the property of forward osmosis membranes.
