WebForward Osmosis mimics water transport by plants, when fresh water is drawn by osmotic pressure into the plant through its roots in the soil. In FO water molecules migrate by diffusion, without energy input, into a more concentrated “draw solution.” Energy for the process is supplied by osmotic pressure difference of the two solutions. WebMay 15, 2015 · As a pretreatment, forward osmosis can lengthen reverse osmosis membranes’ lifespan and promote overall system health by reducing the needed disinfectants and other pretreatment options. The process should use less energy than reverse osmosis, Ela says, since it’s driven by thermodynamics.
