BLOG ON MASS TRANSFER IN REVERSE OSMOSIS Reverse osmosis (RO) is a widely used water treatment process that removes contaminants and impurities from water by using a semi-permeable membrane. The transport of solutes across the membrane in RO is driven by mass transfer, which involves the movement of molecules from one phase to another. In this blog, we will discuss mass transfer in reverse osmosis and some relevant formulas. Mass transfer is the movement of molecules from one phase to another, which is driven by differences in concentration, pressure, and temperature. In reverse osmosis, the mass transfer of solutes across the membrane occurs due to a concentration difference between the feed and permeate streams, as well as a pressure difference across the membrane. Fig 1: Reverse Osmosis principle Representation The driving force for mass transfer in reverse osmosis is the difference in concentration between the feed and permeate streams, which is represented by the solut...
