Abstract:
The paper presents developing Kedem-Katchalsky equations for binary non-homogeneous non-electrolyte solutions. The obtained equation describes the volume flux (Jv) depending on parameters of a membrane (reflection, a, hydraulic permeability, Lp, and solute permeability, omega coefficients), solution parameters (concentration, Ck, density, rho, kinematic viscosity, v and diffusion coefficient, D) and concentration Rayleigh number (Rc). In order to verify of the elaborated equation of Jv for the single-membrane system, there were made the calculations of the dependence: Jv = f(deltaC)(R(C),zeta s = const) Jv = f(R(C))(deltaC, zetta s = const), and Jv = f(zetaS)(R(C),deltaC = const), for aqueous glucose solutions and the membrane made of bacterial cellulose.

Pore Transport and Ion-Pair Transport
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct microscopic...
