WebIn reverse osmosis (RO), pressure that exceeds a system’s osmotic pressure is applied to that system. The pressure forces the higher-concentration solution back across the semipermeable membrane, leaving solutes that are blocked by the semipermeable membrane behind. Typically, reverse osmosis water treatment results in a rejection of ... http://www.tjprc.org/publishpapers/2-67-1636194566-18IJMPERDDEC202418.pdf

Give the pressures you can read on your pressure gauge in any unit to get the TMP. * If you do not measure the pressure put 0 (Zero) in the box. The calculation of TMP uses the formula: (Inlet pressure + Outlet pressure)/2 - Permeate pressure.
