WebAug 29, 2014 · The term “passage” is the reciprocal of the term “rejection”. Salt transport or lack of transport through the membrane barrier layer is described as “salt rejection” and it is the inverse of “salt passage”. Examples of the equations are: Salt Passage = (Cp / Cf) X 100. Permeate TDS = Cp. Feedwater TDS is designated as Cf. WebFor example, when the feed water contains 300 ppm total dissolved solids (TDS), the product water may have 15 to 30 ppm (95% and 90% rejection ratio respectively).
