WebCells use forms of desalination to regulate their osmotic pressure. One device used to do this is an aquaporin: Introduction to aquaporins Aquaporins in nature. Aquaporins are proteins contained in the membranes of bacteria, plant and animal cells. They allow the passage of water across the cell while holding back ions and other solutes. WebForward osmosis (FO) is a water separation process which uses a semipermeable membrane and the natural energy of osmotic pressure to separate water from dissolved solutes. In a FO system, a feed solution (such as industrial wastewater effluent) flows on one side of the membrane, while a solution of higher TDS concentration (the draw …
