Study of Unstirred Ternary Non-Ionic Solutions Transport in a Double-Membrane System

Non-equilibrium thermodynamic model equations describing transport properties of non-ionic and heterogeneous n-component solutions have been studied in a double-membrane system. The system is composed of two complexes: boundary layer/membrane/boundary layer. Definitions of hydraulic permeability (L?_p), reflection (??^*) and diffusive permeability (??) coefficients of the double-membrane system and relations between the coefficients of the double-membrane system (L?_p, ??^*, ??) and the respective quantities of the single membranes of the system (L_p, ?*, ?) are given. The validity of the model has been checked in the case of binary and ternary solutions, using a membrane cell with horizontally mounted membranes. The diffusive permeability and reflection coefficients were determined as functions of solution concentration and gravitational configuration.
