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.
