✦ Synopsis

linear ditrerentiat equations for the transport of water and sait through non-ideal membranes are written down. The first-order forms of these equations are derived from mathematical considerations_ The equations are integrated for steady state flow across a homogeneous membrane. leading to noniintar first-order transport equations. The constants in these equations may be transformed to the well knoicn transport coefficients which evolve naturaliy without additional assumptions. A number of methods arc listed by which the intrinsic coefiicients of homogeneous. composite and imperfect membranes may be measured and the applicability of the first-order equations may be determined_ OF SYMBOLS 4-i area of membrane c concentration l3.
